The Solar System + Planets
What is the Solar System
The solar system contains planets, moons, sun, asteroid belts and Comets. The solar system is just a group of planets and a sun. Our solar system is moving in a spiral movement. This is because the sun's gravitational pull is making the planets orbit the sun. Some planets have there own moon orbiting it. This is the same reason as the sun because of it's gravitational pull.
The order of planets closer to the sun:
*Mercury- The planet closest to the sun. This is also the smallest planet.
*Venus- It has a very think atmosphere. Therefore it traps the heat inside the planet making it the hottest planet in the solar system.
*Earth- This is the third planet from the sun and the only planet known to have a life form.
*Mars- It is usually called the red planet. It is the second smallest planet.
*Jupiter- It is bigger than all the planets combined making it the biggest planet.
*Saturn- It is surrounded by an icy ring. It is very similar to Jupiter.
*Uranus- Despite of it's humorous name, the planet seems to be flipped to it's side.
*Neptune- Neptune is the furthest planet from the sun. It is surrounded by icy moons followed by series of dark rings.

Our planet Earth
Earth is about 150 million km away from the sun making it the third planet away from the sun. It is believed that it is the only planet that has life form in it. It has one moon orbiting around it, which takes 24 hrs to orbit or 1 day.
It is about 12 800 km in diameter.
Has a surface gravity of 10N/kg.
It takes 365.25 days for it to make a full orbit around the sun.
The mass of Earth is 6x10^24 kg.
It's average surface temperature is 20˚C.

Earth's Atmosphere
Earth's Crust= It has the water and the land.Temperature 23˚C and 0km from Earth.
Stroposphere= It has the mountains. Temperature -50˚C and 15km from Earth.
Stratosphere= It is where the planes fly. Temperature -70˚C and 50km from Earth.
Ionosphere Temperature -200˚C and 80 km from Earth.

Saturn
The planet Saturn is the second biggest planet in the solar system, with a diameter of 9x12 800km. It has at least 56 moons orbiting it, 8 of them are large. Saturn is named after 'Saturn', the Roman god of agriculture. Saturn is the furthest planet that we can see without a telescope. The visual colour of Saturn is band of yellow and gold. The layers of Saturn are Rocky Core, metallic hydrogen, helium droplet and circulating cells of hydrogen and helium.
Asteroid
Asteroid is a type of rock the wonders in space. It's size is about a few feet to a several miles of diameter. Smaller asteroids are called meteoroids. Between Mars and Jupiter the asteroid belt can be found. The asteroid belt is where most of the asteroids can be found in our solar system.
Comets
Comets are huge chunk of ice and rock left over from the solar system. As comets head for the sun, the ice evaporates leaving a trail of glowing line. When seen at earth it looks like a shooting star. Comets are very use full for scientist, it serves as a time capsule preserving past information.
