Planet and star formation starts with a lot of material collapsing, falling down onto itself because of gravity. In the middle of this, a protostar is being formed. This star will then start to get warm and eventually glow. "Around this forming star, there will be a round, circulating area. This area is called a disk and is full of a lot of material.
