how are planets formed
Report Abuse. Planets are formed from huge disks of gas and dust that surround a newly-formed star. Clumps start to form in the disk where bits of matter bump into each other and start to stick together.Over time these clumps get bigger, and they have more of a gravitational pull on the surrounding matter.nstead there was in its place a large cloud of gas and dust called a nebula. Over many millions of years the immense gravity of this large cloud caused the dust and gas to slowly fall inward towards its center. As matter in the cloud fell towards the center it began to spin.
