Planets: A Book Filled With Facts For Children

By Bold Kids

A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best theory for the formation of planets is known as the nebular hypothesis. This theory states that a protoplanetary disk erupts from the collapse of an interstellar cloud. A young protostar then orbits the disk.
