The Sun

The Sun
(Star of the Family)
Planet word comes from Greek ,which means „wandering star“.
Sun is the heaviest among Solar System. If we take total mass of whole Solar System, the Sun would be 99.86% of the total.
Sun is a ball of hot,burning gases.
Sun is the nearest star to the Earth.
Sun is the source of all energy for life on Earth.
On the Sun's surface, there are dark patches known as sunspots. These are patches of gas that looks dark since they are cooler than their surroundings.
The light from the Sun takes approximately 8 minutes 20 seconds to reach the Earth.
At the surface of the sun,the temperature is about 6000 degree Celsius but near the center of the sun, the temperature is about 15 to 20 million degree Celsius.

Mercury
(Inner Most Planet)
Mercury is named after messenger of the Roman gods.
Mercury is the closest planet to the Sun.
Mercury has large variations of temperature during 24 hours.In day -time it is about 400 degree C and in the night time it falls down to -180 degree C.
Mercury is also the smallest planet and its orbit is the most not fully circular.
Mercury does not have any satellite.
There is no water or atmosphere on Mercury.
Mercury can be seen with naked eyes.
Mercury has shortest year among all planets. A year on Mercury lasts 88 days as it takes Mercury 88 days to orbit the Sun.
There are no seasons on Mercury's surface

Venus
(The Veiled Planet)
Venus is surrounded by thick cloud cover, that is why it is called „Veiled Planet“.
Venus is the brightest and the hottest planet.It is the brightest object in the night sky after the moon.
Venus is named after Roman goddess of love and beauty. Sometimes it is also referred as a „Planet of Romance“.
Venus rotates so slowly that its one typical day lasts approximately 244 Earth days. It has the slowest rotation in Solar System.
Venus reaches its maximum brightness shortly before sunrise or shortly after sunset,so it is also known as the Morning Star or Evening Star. It can sometimes be seen with the naked eye.
Venus is also known as „Sister“ or „Twin“ planet to earth because of its similar size and mass to Earth.
Although Venus is the 2nd planet from the Sun,it is the hottest because it has a dense atmosphere made up of so-called „greenhouse gases“.

Earth
(The Blue Planet)
It reflects about 1/3rd of sunlight it receives.The Earth’s atmosphere scatters the light and creates a blue effect, so it is also called Blue Planet.
It is also known as watery planet, because 70% of its surface is covered by water.
It is the only planet having life.
It orbits the Sun once in about 365 Earth days.
It rotates on its own axis creating day and night. It takes 24 hours to do that.
It revolves around sun, due to its tilt, seasons are created.
Due to gravity, the layer of gases remains attached to it (which is known as atmosphere) which prevents too much heat or UV rays from Sun reaching Earth.
Moon is the only satellite of the Earth. .
Mars
(The Red Planet)
Mars has approximately half the diameter of Earth.
It has two satellites.
The gravity of Mars is half of the Earth's .
Mars also has the largest dust storms in the Solar System.
Mars is named after the Roman god of war.
Mars is often described as the "Red Planet", as the iron oxide prevalent on its surface gives it a reddish appearance. Actually it's the rusting process on the surface of the Mars . Jupiter
(The Giant Planet)
It is named after the Roman god Jupiter (ruler of Roman gods) .
Jupiter is the largest planet within the Solar System.
Jupiter is also known as a stormy planet.
It has a great Red Spot, it is rotating storm system inside the planet. This red spot is also called „The Eye of the Jupiter“.
This is also a windy planet as the fast rotation causes high winds.
Jupiter rotates faster than any other planet and has the shortest day of all the planets. It completes one rotation in 10 hours.
It has 16 planets.
Jupiter is so big that you could fit all the other planets in the Solar System inside it.
On Jupiter,one would weigh 2.4 times more as compared to Earth because gravity here is higher than the Earth.

Saturn
(The Jewel Planet)
It is named after the Roman god Saturn.
Saturn is classified as a gas giant planet.
It has 22 known satellites.
It takes Saturn 10,759 Earth days (or about 29½ years), to finish one revolution around the Sun.
Saturn is the furthest planet from Earth that can be seen without the help of a telescope.
Saturn is the second biggest planet, but it's also the lightest planet.
Saturn has such a low density that it would float if put in water.
Saturn's rings are made of many pieces of rocks and ice.
Saturn has the greatest number of known moons of any planet in the Solar System.

Uranus
(A planet on its side)
Uranus is a very cold planet, it is also known as Ice Giant. It receives 370 times less sunlight than Earth as it is far away from the Sun.
Uranus is named after the Roman god of the sky.
Uranus is tilted in such a way that a season lasts there for 20 years.
Uranus appears to lie on its side.
Uranus is the only planet, which rotates on its axis from east to west.
Uranus has 27 known satellites.
Its core is very rocky.
Uranus is a very cold planet ,it receives 370 times less sunlight than Earth as it is far away from sun as compared to Earth. .
Uranus appears greenish in color,it happens because methane gas present on the planet absorbs the reddish colours from the sunlight .

Neptune
(The Last Giant)
Neptune can be seen with naked eye.
Neptune has 8 known satellites.
As Neptune is very far from Sun, it completes an orbit on average every 164.79 years.
Neptune was the first planet found by mathematical prediction.
Neptune is known to be the coldest planet in Solar System.
There is a large white cloud in Neptune's atmosphere, that moves around rather quickly.It has been named Scooter due to its scooting around the atmosphere.
Neptune is very similar to Uranus although smaller.
