The nebular theory posits that the solar system formed from a rotating cloud of gas and dust, known as a solar nebula. The process begins with the gravitational collapse of this nebula, leading to the formation of a protostar at its center. As the protostar continues to accumulate material, it ignites nuclear fusion, forming a star, while the remaining material flattens into a rotating protoplanetary disk. Within this disk, particles collide and coalesce to form planets, moons, and other celestial bodies.
