1Our solar system has eight different planets that all travel around the Sun.
2Mercury, the closest planet, is extremely hot during the day and freezing at night.
3Venus is covered in thick clouds that trap heat like a greenhouse.
4Earth is the only planet we know that has liquid water and living things.
5Mars looks red because its dusty surface is full of rusty iron.
6Jupiter is so large that more than one thousand Earths could fit inside it.
7Saturn is famous for its beautiful rings, which are made of ice and rock.
8Uranus spins on its side, like a ball rolling around the Sun.
9Neptune, the furthest planet, has the fastest winds in the whole solar system.
10A year on Neptune lasts about one hundred and sixty-five Earth years.
11Small rocky objects called asteroids orbit in a belt between Mars and Jupiter.
12Telescopes help us study these distant worlds without ever leaving our own planet.
