Quick Facts

Unit: 11: The Earth and Universe
Topic: The Solar System and the Planets
Domain: Earth & Space

Eight planets, one reason

Study Tip

Do not learn the eight planets as eight lists. One fact explains most of it: close to the sun it was too hot for gas and ice to stay, so only rock survived, and far out there was vastly more material to build with. Size, composition and moons all follow from that.
