Solar System - Science Olympiad Questions and Answers Rated A+ How did the terrestrial planets form? In the proto-Solar-Sytem, after the sun formed, the rest of the materials orbiting close around it began to clump together too. However, closer to the sun, lighter materials like gases blew away and only rocky material was left, causing the four terrestrial planets, and some of their moons, to form. What are the characteristics of Terrestrial Planets? Solid bodies with a core surrounded...
