There are eight major planets in orbit around the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Each has its own interesting features, including moons and rings.

There are comets, asteroids, meteoroids, and dwarf planets such as Pluto and Eris. There's the asteroid belt between Mars and Jupiter, the Kuiper belt past Nepyine, and the Oort cloud, a spherical shell of rocks and ice that surrounds the entire solar system.
