What theory describes the formation of our solar system from a nebula cloud?

The correct response is based on the Nebular Theory, which is a widely accepted explanation for the formation of the solar system. This theory posits that the solar system originated from a giant rotating cloud of gas and dust, known as a nebula. Over time, due to gravitational forces, the nebula began to collapse, leading to the formation of the Sun at the center and the planets, moons, asteroids, and comets in the surrounding disk. The process involves the condensation and clumping of material into larger bodies, ultimately leading to the organized structure of our solar system.

The Heliocentric Theory describes the model where the Sun is at the center of the solar system, but it does not explain how the solar system was formed. The Big Bang Theory addresses the origin of the universe itself rather than solar systems specifically. Cosmic Theory is not a recognized term in the context of solar system formation. Therefore, the Nebular Theory is the appropriate choice that specifically addresses the process of how our solar system came into existence from a nebula cloud.
