The Inner Planets (Rocky Planets)
These planets are closest to the sun and are made mostly of rock and metal.
- Mercury: A small planet with no air, very hot during the day and freezing at night.
- Venus: Covered in thick clouds that trap heat like a giant oven!
- Earth: The only planet we know of that has life and liquid water.
- Mars: Home to the largest volcano in the solar system, Olympus Mons.
The Outer Planets (Gas & Ice Giants)
These planets are very far away and are much larger than the inner planets.
- Jupiter: So big that 1,300 Earths could fit inside it!
- Saturn: Its rings are made of billions of chunks of ice and rock.
- Uranus: This cold planet is blue-green because of methane gas.
- Neptune: The windiest planet; winds can reach 1,200 miles per hour!
