Astronomers believe that the solar system formed from a giant rotating cloud of gas and dust called the solar nebula. As the cloud collapsed under its own gravity, it began to spin faster and eventually formed a flat, rotating disk. The Sun formed at the center, while the planets and other objects in the solar system accreted from the material in the disk.
Protoplanets are very small planets, about the size of a moon. Astronomers believe these celestial objects are formed during the creation of a solar system.
