The Solar System
The Solar System is made up from stars, the Sun, Moon, and the nine planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

Pluto

The smallest planet; It is the coldest planet.
Neptune

· Neptune has two thick and two thin rings surrounding it.
· It is approximately 2.8 billion miles away from the Sun.
Uranus

· Uranus is almost identical to Neptune.
· Uranus is made of Methane ice.
Saturn

· Saturn is the 2nd largest planet in the solar system.
· 755 Earths could fit inside Saturn.
Jupiter

· Jupiter is the largest planet in the Solar System.
· Jupiter is mostly made of a gas called hydrogen.
· Jupiter has a small rocky core at its centre and it is bigger than the Earth.
Mars

· Mars is often called the “Red Planet” because of its colour.
· It is about half the size of the Earth.
· In Mars, one day is 24½ hours long.
Earth

It is often called “The Water Planet” because it is the only planet in our Solar System which has liquid water on its surface (about 70% of the surface of Earth is covered by water).
Venus

· It takes Venus 243 days to spin around one full time.
· Venus is about the same size of the Earth.
· It is very hot all over the whole planet (465˚C).
Mercury

· It is the closest planet to the Sun.
· It has no moons.
· It is the hottest planet in the day; At night, because Mercury spins so slowly, you could freeze to death.
The Sun

· The Sun is a star.
· It is made of gases called hydrogen and helium.
· The outside temperature of the Sun is 11,000ºF.
· More than one billion planet Earths could fit inside the Sun because it is so big.
The Moon

· The Moon is moving about one inch away from the Earth each year.
· It has a diameter of about 3,476 kilometers.
Stars
· There are roughly 100 billion stars in the galaxy.
· The Sun is the closest star to Earth.
· It would take about a hundred thousand years to get to the closest star using the fastest space ship on earth.
· A star is made out of a bunch of burning gas made of Helium and Hydrogen.
