A solar system is a star and all the objects that orbit it, including planets, moons, asteroids, and comets. The Solar System consists of the Sun, eight planets, and three dwarf planets. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The dwarf planets are Pluto, Eris, Makemake, and Haumea.
