Hidden Internet | What is Mariana Web Explained | Fireup Facts


In this previous Article of our hidden we series, we had discuss about surface web, deep web and dark web. And if you fell scary after listening all of them then that are nothing, until we get to the "deepest part of the web, where people don't want you to go," the so-called "Mariana's Web".

The legend of Mariana's Web appears to get its name from the deepest part of the ocean, Mariana's Trench, It's supposedly the deepest part of the ocean, If you don’t have seen our video on Mariana trench, then you can watch it by clicking on the “I” button. But today we will discuss about, Mariana Web and its Myth.

It is to be believed that Mariana web is the portion of web that contains a lot of secrets as you can think. Here you'll find "the darkest secrets humanity has in its history", “the secret location of Atlantis” and "the Vatican secret archives", or a database of archives belonging to the most powerful intelligence agencies on Earth.

Extreme content of all kinds, including terrorist tutorials, pages with prohibited adult material, and unimaginable subject forums, for example, could be found in these layers.

But, what is so secretive about Mariana’s Web that it needs to be hidden in such a way? There is no 100% correct answer to this, so there is no way to pinpoint exactly what kind of information can be found there. What is known is based on reports from experienced Deep Web users and specialized forums.

Some people point out sites that make hitmen available. Companies specializing in the sale of banned and strictly military weapons could also be found in these farthest layers of the network. In the most sinister reaches of the web there may even be the trade of human beings, rare animals and organs.
It is also believed that Mariana web is so secured that a Quantum computers are required enter in Mariana Web, which currently only exist in science fiction.

For many, the whole concept of these hidden pages and all their mysteries are just internet legends … What do you think? Do not forget to comment!

Hidden Internet | What is Deep Web & Dark Web Explained | Fireup Facts


Everyone knows what the internet is. With the way the world is today you just can’t live without it. The way that internet use is tied into just about every aspect of life now, it’s hard to imagine what we did for all those years before it came along.

The web is a great thing but it does have its limitations. Oh, you might not think that it does when you come across something that’s pretty distasteful, but believe me, there is worse that is available with the click of a mouse.

Our Internet is divided into three groups that are: Surface web, Deep web and Mariana Web.

What is Surface Web?
The surface web is that portion of web which we see in daily life. It can be Browse, Surf and Crawl with regular browser and regular ISP, because the links on surface web are indexed in every search engines like Google, Yahoo and Bing.
According to one source, as of June 14, 2015, Google's index of the surface web contains about 14.5 billion pages.

How is the surface web created?
Search engines construct a database of pages on the Internet through the use of programs called Web spiders. The spider receives a copy of each page and catalogues it, keeping the appropriate information for quick retrieval at a later date. When a new page is linked, it is eventually inspected by the spiders and added to the list of reachable pages; the surface Web.

What is Deep Web?
The “Deep Web”, also referred to as the “Hidden Web” or “Deepnet”, has plenty to offer those that are bored with the regular internet. It’s an underground world that operates separate from the regular internet, and you can find just about anything you want to on there. It’s actually much larger than the regular internet but there is a reason that it isn’t publicized very often. Most of the deep web contains harmless information, but it can also foster serious criminal activity. The deep web is quite large; several times the size of the surface Web. The phrase "deep web" was coined by Mike Bergman, founder of Bright Planet.

The content of the deep web is hidden behind HTTP forms, and includes many very common uses such as web mail, online banking, and services that users must pay for, and which is protected by a paywall, such as video on demand, some online magazines and newspapers, and many more.

Content of the deep web can be located and accessed by a direct URL or IP address, and may require password or other security access past the public website page.

There is an also term which is most frequently used when we came across at Deep web, that is, Dark Web. The dark is the part of deep web but this is not for public and even not access by government itself. It is only used by Criminals for their evil deeds. Each and every bad things you can imagine, can be found at dark web, form online Drugs to Hitman.

A December 2014 study by Gareth Owen from the University of Portsmouth found that the most commonly hosted type of content on Tor was child pornography, followed by black markets, while the individual sites with the highest traffic were dedicated to botnet operations (see attached metric). Many whistleblowing sites maintain a presence as well as political discussion forums. Sites associated with Bitcoin, fraud related services and mail order services are some of the most prolific. To counter the trend of controversial content, the artist collective Cyber twee held a bake sale on an onion site.

10 Interesting Facts About Neptune (The Smallest Ice Giant!!!)


Neptune is the eighth planet from the Sun and last of the known planets. While it is the third largest planet with respect to mass, it is only the fourth largest in terms of diameter. Due to its blue coloration, Neptune was named after the Roman god of the Sea.

Interesting Facts about Neptune:

Neptune is the eighth planet in our solar system, and is named for the Roman god of the sea
The Greek counterpart is Poseidon. It's also the most distant planet from the sun... a distinction it won when Pluto was demoted to the status of "dwarf planet" in 2006. Neptune was also the first planet to have its existence predicted by mathematical calculations, before it was actually seen by a telescope.

Neptune is the smallest of the ice giants
It has 13 known moons, and is similar in size to Uranus, making it the smallest of the four gas giant planets in the outer solar system. Neptune's atmosphere contains hydrogen, helium and methane, giving it a blue color that is largely the result of the absorption of red light by the methane in the atmosphere.

Neptune's gravity is slightly stronger than Earth's
A 100 pound person on Earth would weigh 114 pounds on Neptune.

A day on Neptune, takes about 16 Earth hour
Like the other planets, Neptune has an elliptical orbit. It is 2.8 billion miles from the sun on average, and takes 165 Earth years to complete a single orbit. In 2011, it completed its first full orbit of the Sun since its discovery in 1846. A day on Neptune, or one revolution on its axis, takes about 16 Earth hour.

Neptune's surface temperatures can reach a frigid -392 degrees Fahrenheit
But in the core of this icy planet, you'll find temperatures comparable to the surface of the Sun! This huge temperature difference between the core and the surface helps create the strongest winds in the solar system -- reaching speeds of 1200 to 1500 miles per hour!

Neptune has a storm similar the Great Red Spot on Jupiter
NASA’s Voyage 2 reveled a giant storm called the "Great Dark Spot," and a patch of cloud called "the scooter" because it circled the planet very fast. In 1994, the Hubble telescope discovered that the dark spot found in 1989 had disappeared and another dark spot had developed.

Neptune has a very thin collection of rings
NASA's Voyager 2 revealed some intriguing new features on its visit to Neptune in 1989. It showed six rings of varying thicknesses. They are most likely made up of ice particles and grains of dust with a carbon-based substance coating them.

Neptune has 14 known moons
The largest of these moons is Triton – a frozen world which spits out particles of nitrogen ice and dust from below its surface. It is believed that Titan was caught by the immense gravitational pull of Neptune and is regarded as one of the coldest worlds in our solar system.

The largest Neptunian moon, Triton, was discovered just 17 days after Neptune itself was discovered

Only one spacecraft has flown by Neptune
In 1989, the Voyager 2 spacecraft swept past the planet. It returned the first close-up images of the Neptune system. The NASA/ESA Hubble Space Telescope has also studied this planet, as have a number of ground-based telescopes.

10 Interesting Facts About Uranus (The Ice Giant!!!)


Uranus is the seventh planet from the Sun. While being visible to the naked eye, it was not recognized as a planet due to its dimness and slow orbit. Uranus became the first planet discovered with the use of a telescope. Uranus is tipped over on its side with an axial tilt of 98 degrees. It is often described as “rolling around the Sun on its side.”

Interesting Facts about Uranus:

Uranus is the smallest of the four “giants”, but is still several times larger than the Earth.  It has a diameter of 29297 miles, or 47, 150 kilometers, compared to the Earth’s diameter of just under 8000 miles, or 12,760 kilometers.

Uranus was named after the Greek sky deity Ouranos, the earliest of the lords of the heavens. It is the only planet to be named after a Greek god rather than a Roman one. Before the name was settled on, many names had been proposed for the new planet, including Hypercronius ("above Saturn"), Minerva (the Roman goddess of wisdom), and Herschel, after its discoverer. German astronomer Johann Bode, who detailed Uranus' orbit, gave the planet its ultimate name. Bode argued that as Saturn was the father of Jupiter, the new planet should be named for the father of Saturn. Bode's colleague, Martin Klaproth, supported his choice and named his newly discovered element "uranium."

Uranus was officially discovered by Sir William Herschel in 1781
It is too dim to have been seen by the ancients. At first Herschel thought it was a comet, but several years later it was confirmed as a planet. Herscal tried to have his discovery named “Georgian Sidus” after King George III. The name Uranus was suggested by astronomer Johann Bode. The name comes from the ancient Greek deity Ouranos.

Uranus rotates on its axis once every 17 hours and 14 minutes
A day on Uranus is 17 hours, 14 minutes and 24 seconds. In other words, a day on Uranus is shorter than a day on Earth. Like Venus, it turns in a retrograde direction which is opposite to the direction Earth and the other six planets turn.

Year on Uranus is 84 Earth Years
Its axis is at 98 degrees, which means it almost lies sideways as it orbits the Sun. This means that the north and south poles of Uranus lie near where the equator is on Earth. During parts of its orbit one or other of the poles directly face the Sun which means the planet gets around 42 years of direct sunlight followed by 42 years of darkness.

Uranus is often referred to as the “ice giant”
While it has a hydrogen and helium upper layer like the other gas giants, Uranus also has an icy mantle which surrounds its rock and iron core. The upper atmosphere of water, ammonia and methane ice crystals gives Uranus its distinctive pale blue color.

Uranus is the coldest planet in the solar system
The minimum surface temperature on Uranus is -224°C, making it the coldest of the eight planets. Its upper atmosphere is covered with a haze made mostly of methane which hides the storms taking place in its cloud decks.

Uranus has two sets of very thin dark colored rings
The ring particles are small, ranging from a dust-sized particles to small boulders. There are eleven inner rings and two outer rings. They probably formed when one or more of Uranus’s moons were broken up in an impact. The first rings were discovered in 1977 with the two outer rings being discovered in Hubble Space Telescope images between 2003 and 2005.

The chemical element, Uranium, discovered in 1789, was named after the newly discovered planet Uranus.

Uranus has a total of 27 moons, most of whom are named after characters in Shakespeare’s Midsummer Night’s Dream.  The five major moons are called Titania, Oberon, Miranda, Ariel and Umbriel.  Umbriel is not from Shakespeare but is the “melancholy sprite” in a poem by Alexander Pope.

10 Interesting Facts About Saturn (The Ringed Planet!!!)


Saturn is the sixth planet from the Sun and second largest planet of the Solar System in terms of diameter and mass. If compared, it is easy to see why Saturn and Jupiter have been designated as relatives. From atmospheric composition to rotation, these two planets are extremely similar.

Interesting Facts about Saturn:

In Roman mythology Saturn was the father of Jupiter, king of the gods
This relationship makes sense given that the planets Saturn and Jupiter are similar in so many respects, including size and composition. The Greek counterpart is known as Cronus, the lord of the Titans. Saturn is the root of the English word "Saturday."

The most common nickname for Saturn is “The Ringed Planet”
A nickname arising from the large, beautiful and extensive ring system that encircles the planet. These rings are mostly made from chunks of ice and carbonaceous dust. They stretch out more than 12,700 km from the planet but are only a mere 20 meters thick.

Saturn is sometimes called "The Jewel of the Solar System"
It is a planet that is nothing like our own. Humans have been gazing up at Saturn for a long time. They have been wondering about it for thousands of years.

Saturn is the flattest planet
Its polar diameter is 90% of its equatorial diameter, this is due to its low density and fast rotation. Saturn turns on its axis once every 10 hours and 34 minutes giving it the second-shortest day of any of the solar system’s planets.

Saturn is a gas giant made up mostly of hydrogen and helium
Saturn is big enough to hold more than 760 Earths, and is more massive than any other planet except Jupiter, roughly 95 times Earth's mass. However, Saturn has the lowest density of all the planets, and is the only one less dense than water, if there were a bathtub big enough to hold it, Saturn would float.

Days at Saturn
Saturn has the second shortest day behind Jupiter. The length of a day on Saturn is 10 hours 32 minutes; and, did you know how scientists measure this data from various planets? They just spot a crater and wait for the crater to rotate back in view, thus determining the length of a day on a planet. However, in Saturn’s case, as there is no solid mass on the planet, they had to take into account the planet’s magnetic field for that matter.

Saturn orbits the Sun once every 29.4 Earth years
Due to the enormous distance at which the planet is positioned with respect to the Sun, Saturn takes 29.4 Earth years to make one revolution around the Sun. Its slow movement against the backdrop of stars earned it the nickname of “Lubadsagush” from the ancient Assyrians. The name means “oldest of the old”.

Saturn has 150 moons and smaller moonlets
All of these moons are frozen, the largest of which are Titan and Rhea. The moon Enceladus also appears to have an ocean hidden below its frozen surface.

A popular moon
Enceladus, one of Saturn’s’ moon is the shiniest object in the Solar system. It is mainly because of the fact that it is made up mostly of ice that reflects almost all of the light that falls onto it.

Visitors to the planet
Only four space crafts have studied this planet. This might be due to the fact that it is at a long distance from Earth as compared to other planets. And they do not have any landing site on the planet because of the lack of solid surface. And the planet’s hot gasses won’t even allow any spacecraft unscathed either.

10 Interesting Facts About Jupiter (The Largest Planet!!!)


Named after the Roman king of the gods, Jupiter is fitting of its name. With a mass of 1.90 x 1027 kg and a mean diameter of 139,822 km, Jupiter is easily the largest and most massive planet in the Solar System. To put this in perspective, it would take 11 Earths lined up next to each other to stretch from one side of Jupiter to the other and it would take 317 Earths to equal the mass of Jupiter.
Jupiter is like a star in composition. If Jupiter had been about 80 times more massive, it would have become a star rather than a planet. Jupiter is the fifth planet from the sun. Jupiter's average distance from the sun is 5.2 astronomical units, or AU. This distance is a little more than five times the distance from Earth to the sun. When viewed from Earth, Jupiter is usually the second brightest planet in the night sky, after Venus.

Interesting Facts about Jupiter:

The first recorded sighting of Jupiter were by the ancient Babylonians in around 7th or 8th BC. 
It is named for Jupiter, the king of the Roman gods and god of the Sky. The Greek equivalent is Zeus, god of thunder. For the Mesopotamians, he was the god Marduk and patron of the city of Babylon. Germanic tribes saw the planet as Donar, also known as Thor.

Jupiter has the shortest day of the eight planets
Jupiter rotates very quickly, turning on its axis once every 9 hours and 55 minutes. This rapid rotation is also what causes the flattening effect of the planet, which is why it has an oblate shape.

One orbit of the Sun takes Jupiter 11.86 Earth years
Jupiter takes 12 Earth years to make one revolution around the sun, so one year on Jupiter is equal to 12 years on Earth. This means that when viewed from Earth, the planet appears to move very slowly in the sky. It takes months for Jupiter to move from one constellation to the next.

Jupiter has at least 67 moons in satellite around the planet
Jupiter has 67 confirmed moons orbiting the planet. These moons are separated into three groups:
  1. Inner moons. These orbit the closest to Jupiter and are sometimes called the Amalthea group. The names of the inner moons of Jupiter are Metis, Adrastea, Amalthea, and Thebe.
  2. Galilean moons. These are largest of Jupiter’s moons and were discovered by Galileo Galilei in 1610 – Io, Europa, Ganymede and Callisto.
  3. Outer moons. These moons are much smaller and further away from Jupiter. They also have irregular, elliptical orbit paths and many are captured asteroids.
The largest of Jupiter’s moons, Ganymede is the largest moon in the solar system
The moons are sometimes called the Jovian satellites and the largest of them are Ganymede, Callisto, Io and Europa. Ganymede is larger than the planet Mercury with a diameter of around 5,268 km.

Jupiter has an extremely powerful magnetic field, like a giant magnet
On Earth, hydrogen is usually gas. But on Jupiter, the pressure is so great inside its atmosphere that the gas becomes liquid. As Jupiter spins, the swirling, liquid metal ocean creates the strongest magnetic field in the solar system.

The Great Red Spot is a huge storm on Jupiter
The red spot is a huge storm that has been continuously going on Jupiter for over 400 years.  Winds inside this storm reach speeds of about 270 mph.  The red spot of Jupiter is the biggest, most violent storm in the known universe, that spot is at least three times the size of earth!

Jupiter’s interior is made of rock, metal, and hydrogen compounds
Below Jupiter’s massive atmosphere (which is made primarily of hydrogen), there are layers of compressed hydrogen gas, liquid metallic hydrogen, and a core of ice, rock, and metals.

Jupiter has a thin ring system
Its rings are composed mainly of dust particles ejected from some of Jupiter’s smaller worlds during impacts from incoming comets and asteroids. The ring system begins some 92,000 kilometers above Jupiter’s cloud tops and stretches out to more than 225,000 km from the planet. They are between 2,000 to 12,500 kilometers thick.

Eight spacecraft have visited Jupiter
Pioneer 10 and 11, Voyager 1 and 2, Galileo, Cassini, Ulysses, and New Horizons missions. The Juno mission is its way to Jupiter and will arrive in July 2016. Other future missions may focus on the Jovian moons Europa, Ganymede, and Callisto, and their subsurface oceans.

10 Interesting Facts About Venus (The Brightest Planet!!!)


Venus is the second planet from the Sun and the third brightest object in Earth's sky after the Sun and Moon. It is sometimes referred to as the sister planet to Earth, because their size and mass are so similar. Venus is also the closest planet to Earth. The surface of Venus is hidden by an opaque layer of clouds which are formed from sulphuric acid.
The planet is named for Venus, the Roman goddess of love and beauty and is the second largest terrestrial planet.

Interesting Facts about Venus:

Venus is the second brightest natural object in the sky
The planet has an apparent magnitude of -3.8 to -4.6, which makes it visible on a bright, clear day.

Venus is sometimes referred to as the “morning star” and “evening star”
Early civilizations thought Venus was two different bodies, called Phosphorus and Hesperus by the Greeks, and Lucifer and Vesper by the Romans. This is because when its orbit around the Sun overtakes Earth’s orbit, it changes from being visible after sunset to being visible before sunrise. Mayan astronomers made detailed observations of Venus as early as 650 AD.

One day on Venus is longer than one Year
Due to the slow rotation on its axis, it takes 243 Earth-days to complete one rotation. The orbit of the planet takes 225 Earth-days which make a year, shorter on Venus than a year on Earth.

Venus is named after the Roman goddess of love and beauty
Venus is the only planet named after a female God, may have been named for the most beautiful deity of her pantheon because it shone the brightest of the five planets known to ancient astronomers.
This may be, in part, due the brightness of the planet and may date back to the Babylonians in 1581 who referred to Venus as “bright queen of the sky”.

Venus is sometimes called Earth’s sister planet
This is because their size is very similar, there is only a 638 km different in diameter and Venus has around 81% of Earth’s mass. They are also similarly located with Venus being the closest planet to Earth. Both planets also have a central core, a molten mantle and a crust.

Venus has no moons nor rings
Billions of years ago, the climate of Venus may been similar to that of Earth and scientists believe that, Venus once possessed large amounts of water or oceans. However, due to the high temperatures produce from the extreme greenhouse effect, this water boiled off long ago and the surface of the planet is now too hot and hostile to sustain life.

Venus rotate in the opposite direction to other planets
Most other planets rotate counter-clockwise on their axis, however Venus, like Uranus, rotates clockwise. This is known as a retrograde rotation and may have been caused by a collision with an asteroid or other object which caused the planet to change its rotational path.

Venus is the hottest planet in the solar system with an average surface temperature of 462°C
Also, Venus doesn’t tilt on its axis which means there are no seasons either. The atmosphere is a dense 96.5% carbon dioxide which traps heat and caused the greenhouse effect which evaporated any water sources billions of years ago.
The temperature on Venus doesn’t vary much between the night and day. This is due to the slow movement of the solar winds across the surface of the planet.

The estimated age of the Venusian surface is around 300-400 million years old
By comparison, the surface of the Earth is about 100 million years old. Six mountainous regions make up about one-third of the Venusian surface. One mountain range, called Maxwell, is about 870 Kilometer long and reaches up to some 11.3 Kilometer high, making it the highest feature on the planet.

Venus also possesses a number of surface features unlike anything on Earth. For example, Venus has coronae, or crowns, ring-like structures that range from roughly 155 to 580 kilometer wide. Scientists believe these formed when hot material beneath the crust rises up, warping the planet's surface. Venus also has tesserae, or tiles raised areas in which many ridges and valleys have formed in different directions.

The atmospheric pressure of Venus is 92 times stronger than Earth’s
This means that any small asteroids entering the atmosphere of Venus are crushed by the immense pressure, which is why there are no small surface craters on the planet. This pressure is equivalent to being around 1,000 km under Earth’s oceans.

Venus has a very weak magnetic field
This surprised scientists, who expected Venus to have a magnetic field similar in strength to Earth’s. One possible reason for this is that Venus has no solid inner core, or that its core is not cooling. Second possible reason may be that Venus is not spinning about its own axis as earth spins.

Venus is the closest planet to Earth
When Venus is in line with Earth and the Sun, it is the closest planet to us, at an average distance of 41 million kilometers away.

10 Interesting Facts About Mercury (The Smallest Planet!!!)



Mercury is the closest planet to the Sun and due to its proximity it is not easily seen except during twilight. Mercury is only the second hottest planet. Despite being further from the Sun, Venus experiences higher temperatures. Being so close to the Sun, the daytime temperature on Mercury is scorching – reaching over 400 °C (752 °F). At night however, without an atmosphere to hold the heat in, the temperatures plummet, dropping to -180°C (-292°F). The surface of Mercury is very similar to our moon. It has a very barren, rocky surface covered with many craters.

Interesting Facts about Facts:
  1. Mercury has been known to humanity since ancient times and although its discovery date is unknown, the first mentions of the planet are believed to be around 3000 BC by the Sumerians.
  2. A year in Mercury is 88 days, yet a Mercury day is 176 Earth days. Mercury is nearly tidally locked to the Sun – also known as a gravitational lock – and over time this has slowed the rotation of the planet to almost match its orbit around the Sun.
  3. Mercury is the smallest planet in the solar system with a diameter of 4,879 km and is one of five planets that is visible to the naked eye.
  4. After the Earth, Mercury is the second densest planet. Despite its small size, Mercury is very dense because it is composed mainly of heavy metals and rock, the main characteristic of terrestrial planets.
  5. Mercury is only the second hottest planet. Venus, though farther from the Sun than Mercury, actually experiences higher temperatures. This is because Mercury has no atmosphere to regulate temperature and results in the most extreme temperature change of all the planets, ranging from -170°C or -280°F during the night to 430°C or 800°F during the day.
  6. The planet has just 38% of the gravity on Earth. This means that Mercury isn’t able to hold the atmosphere it has and it instead gets blown away by solar winds. However those same solar winds are also bringing in new gases, radioactive decay and dust from micrometeorites, replenishing the atmosphere.
  7. Mercury has a weak magnetic field whose strength is about 1% of the magnetic field on Earth.
  8. Mercury has no moons or rings because of its low gravity and lack of atmosphere.
  9. Mercury has a large iron core that is around 40% of its volume (compared to a core volume of 17% for Earth) in its center whose radius is 1800 to 1900 kilometers (1100 to 1180 miles). Scientists believe the core of Mercury is probably molten.
  10. It is difficult to reach the planet due to its proximity to the Sun and any spacecraft visiting would need to travel 91 million kilometers into the Sun’s gravitational potential well. The Mariner 10 visited during 1974-75, flying by Mercury three times and mapping half its surface. On March 24, 1975 it ran out of fuel and is still believed to be orbiting the Sun. The MESSENGER probe was launched in 2004 to explore Mercury’s high density, its geological history, the nature of its magnetic field and more. Another mission, Bepi Colombo, is to be launched in 2015 by the European Space Agency and Japan is expected to reach Mercury in 2019.

10 Interesting Facts About Earth (The Blue Planet!!!)



Earth is the third planet from the sun and the fifth largest in the solar system in terms of size and mass. It is the densest of all the planets, having density equal to 5513 kilogram per cubic meter. Earth is the only planet in the solar system not named after a mythological being. Instead, its name is derived from the Old English word "ertha" and the Anglo-Saxon word "erda" which means ground or soil. Earth was formed somewhere around 4.54 billion years ago and is currently the only known planet to support life - and lots of it.

Earth Planet Profile
Equatorial Diameter: 12,756 km
Polar Diameter: 12,714 km
Mass: 5.97 x 1024 kg
Moons: 1 (The Moon)
Orbit Distance: 149,598,262 km (1 AU)
Orbit Period: 365.24 days
Surface Temperature: -88 to 58°C

Earth is the only planet not named for a mythological God or Goddess
The other seven planets in the solar system were named after Roman gods or goddesses. For the five visible to the naked eye, Mercury, Venus, Mars, Jupiter and Saturn they we named during ancient times. This Roman method was also used after the discovery of Uranus and Neptune. Although word “Earth” comes from the Old English word “ertha”, meaning ground or land, which sometimes worship as the goddess in Hinduism.

The Earth was once believed to be the Centre of the Universe
For 2000 years ancient astronomers believed that the Earth was static and had other celestial bodies travelling in circular orbits around it. They believed this because of the apparent movement on the Sun and planets in relation to their viewpoint. In 1543, Copernicus published his Sun-centered model of the Solar System which put the Sun at the Centre of our solar system.

Earth is the densest planet in the Solar System
The density of Earth differs in each part of the planet, the core, for example, is denser than the Earth’s crust, but the average density of the planet is around 5.52 grams per cubic centimeter. Which makes earth the densest planet of the solar system.

The Rotation of the Earth is gradually slowing down
Recent discoveries has shown that he deceleration of the Earth’s rotation is very slow, approximately 17 milliseconds per hundred years. Eventually this will lengthen our days but it will take around 140 million years before our day will have increased from 24 to 25 hours.

Earth’s Atmosphere
Earth’s atmosphere is composed of 78% nitrogen, 21% oxygen, and trace amounts of other gases including argon and carbon dioxide. While 70% of earth’s surface is covered with water. The remainder consists of continents and islands which together have many lakes and other sources of water.

Earth has a powerful magnetic field
The Earth is like a great big magnet, with poles at the top and bottom near to the actual geographic poles. The magnetic field it creates extends thousands of kilometers out from the surface of the Earth – forming a region called the “magnetosphere“. Scientists think that this magnetic field is generated by the molten outer core of the Earth, where heat creates convection motions of conducting materials to generate electric currents. Be grateful for the magnetosphere. Without it, particles from the Sun’s solar wind would hit the Earth directly, exposing the surface of the planet to significant amounts of radiation. Instead, the magnetosphere channels the solar wind around the Earth, protecting us from harm.

The Day of Earth is Not 24 Hours
It actually takes 23 hours, 56 minutes and 4 seconds for the Earth to rotate once completely on its axis, which astronomers refer to as a Sidereal Day. Now wait a second, doesn’t that mean that a day is 4 minutes shorter than we think it is? You’d think that this time would add up, day by day, and within a few months, day would be night, and night would be day.
But remember that the Earth orbits around the Sun. Every day, the Sun moves compared to the background stars by about 1° – about the size of the Moon in the sky. And so, if you add up that little motion from the Sun that we see because the Earth is orbiting around it, as well as the rotation on its axis, you get a total of 24 hours.
This is what is known as a Solar Day, which – contrary to a Sidereal Day – is the amount of time it takes the Sun to return to the same place in the sky.

A year on Earth isn’t 365 days
It’s actually 365.2564 days. It’s this extra .2564 days that creates the need for a Leap Year once every four years. That’s why we tack on an extra day in February every four years.

The Gravity between the Earth and the Moon causes the tides on Earth
This effect on the Moon means it is tidally locked to Earth. Its rotation period is the same as its orbit time so it always presents the same face to Earth.

The Earth has an Ozone Layer which protects it from harmful solar radiation
This shell is a special type of oxygen that absorbs most of the Sun’s powerful UV rays. But recently scientist shows that the ozone layer is being continuously damaged by global warming.
