According to the nebular theory, the planets formed from a process called . after our protosun formed, remaining dust and gas from the nebula collided, combined, and gravitated together to form the planets.

According to the nebular theory, the planets formed from a process called accretion.

Explanation:

The nebular theory is a theory that explains the formation of solar systems. After the formation and growth of the proto-star, the gases and dust in the nebula form a disk and spiral quickly around its center under the influence of its gravitation. This long and destructive process ends with the formation of planets, characteristics of which depend on their distance from the star. The term from astrophysics referring to this way of planet formation is accretion. Planets are not only astronomical objects created by accretion processes but galaxies and stars as well.
