Question

Quizplus · Accepted Answer

The most widely accepted theory states that our Solar System formed from a coalescing cloud of dust and gas, which was cold rather than fiery hot. As the cloud collapsed under the force of gravity, it began to spin and flatten into a disk, with the vast majority of material collecting in the center to form the Sun. The smaller bits of material coalesced into planets, moons, asteroids, and other objects orbiting the Sun.
