The correct order of planetary object class during their formation starts with planetesimals, which are small solid objects thought to exist in protoplanetary disks. These coalesce to form protoplanets, larger bodies that are the building blocks of planets. Finally, these protoplanets accumulate enough mass and undergo processes such as differentiation and clearing their orbits to become planets.
