The video explains the formation of planets in the solar system through the nebular hypothesis. Initially, a cold, spinning cloud of gas, known as the solar nebula, formed due to uneven gas distribution. Gravity condensed the gas, forming an accretion disk and eventually a protostar, the Sun. Protoplanets formed from clumps of gas, dust, and rock, growing by trapping material. The nebular hypothesis explains the arrangement of planets, with rocky planets closer to the Sun and gas giants farther away. Although not directly testable, it provides a useful framework for understanding solar system formation.
