Small space objects clump together from many different directions giving it a odd shape. once the object gets enough mass, the gravity starts forcing the object into a ball. For example space dust kept on connecting (when in orbit around the sun) until the mass was large enough to force the space dust ( which by then was basically rock) into a large uninhabitable ball which after pulling gasses in to form an atmosphere, turned into what we call now earth.
