Quizplus · Accepted Answer

The solar nebular theory is the current prevailing theory for the birth of a solar system. This theory suggests that our solar system formed from a cloud of gas and dust called a nebula, which collapsed under its own gravity and formed a spinning disk. The center of the disk became the sun, while the leftover material coalesced into planets, moons, asteroids, and other objects in orbit around the sun. This theory is supported by observations of other protoplanetary disks around young stars in our galaxy.
