Nebular theory posits that stars and planetary systems form from a rotating cloud of gas and dust, known as a nebula. Initially, gravitational forces cause the nebula to collapse, leading to the formation of a protostar at the center. As the protostar accumulates mass, nuclear fusion ignites, creating a star, while the remaining material in the disk around it begins to coalesce into planets, moons, and other celestial bodies. This process explains the formation of solar systems, including the arrangement and composition of planets.

It fits the known data.
The nebular theory was proposed in 1755 by the German philosopher Immanuel Kant and was further developed by French mathematician and astronomer Pierre-Simon Laplace in 1796.
The nebular theory attempts to explain the formation of the solar system through the collapse of a giant cloud of gas and dust, known as a solar nebula. According to this theory, gravitational forces caused this nebula to contract and spin, leading to the formation of the Sun at its center and the planets, moons, and other celestial bodies from the surrounding material. This process also accounts for the distribution of angular momentum and the orbits of the planets. Overall, the nebular theory provides a framework for understanding the origins and organization of our solar system.
