Exploring the Formation of the Solar System

The video explores the solar system, its components, and historical models of its structure. It discusses the challenges in defining planets and describes the solar system's formation from a collapsing cloud. The video concludes with observations of similar processes in the galaxy.

Why are the inner planets rocky and the outer planets gas giants?

• The inner planets have stronger gravity.

• The inner planets are older.

• The outer planets captured more gas.

• The Sun's heat evaporated gases on the inner planets.
