Facts about the Solar System

We all know that our solar system consists of nine planets all of them revolving around the sun. But there are other interesting things which most of us don’t know. I discovered some while browsing through different websites. So, here I will share with you some interesting facts related to the fascinating system.
The gases and dust particles assembled billions of years ago and started the formation of solar system. They all assembled to form the sun and different planets.
The sun is one among the several stars that you see in the night sky. This is the star which lies close to our planet and hence we all feel the heat. There are 70,000, 000, 000, 000, 000, 000, 000 stars in the universe and sun is one of them.
The sun is surrounded by Mercury, Venus, and Earth. Then there is an asteroid belt after which Jupiter, Saturn, Neptune, Uranus and Pluto follow. The first three planets near the sun are the dense rocky planets while the other planets which lie after the asteroid belt are less dense gas planets. There are dwarf planets as well. These are Ceres lying in the asteroid belt, Pluto and finally the Eris located miles beyond Pluto.
Asteroids are the rocky planets that lie between the Jupiter and Mars orbit. These 90,000 asteroids are the remains of the solar system when it was formed.
Sun forms about 99% of the solar system. Besides planets and asteroids there are 172 moons of different planets, comets and dust.
Our earth is hit by about 10,000,000 kg of meteors everyday. So, lots of dust falls on our planet everyday.
The Saturn is one such planet in our solar system which will float on water if it is placed on it. That’s true! The planet is less dense than the water and if any such thing happens then it would be great to see.
Winds on Neptune are moving at the speed of 2000 km.
Mercury might be the nearest to the Sun but Venus is the hottest planet of our solar system.
Jupiter is the largest one. It is so large that it can hold around 1300 earth in itself.
Pluto takes 248 years to complete one orbit around the sun. It was discovered in 1930, so, we will celebrate its first orbit anniversary in 2178.
The red spot on Jupiter is the hurricane storm.
When Pluto is close to the sun its atmosphere is thin but when it is far away then its atmosphere freeze so that the collapse on the planet and Pluto resembles a comet.
The comets are lumps of ice which come from outer space into our solar system. When they come close to sun then the nucleus sublimates forming a cloud of dust and gas.

All these facts which listed here are just the tip of the iceberg. I suggest you to browse the websites and discover your universe yourself.
