This paper analyzes the main ideas of the formation of celestial bodies in accretion and protoplanetary disks. The mechanisms of the radial and orbital migration of celestial bodies are considered. According to the results of modeling the formation of small bodies and the growth of their sizes and masses occurs at stable libration points of orbital resonances. The appearance of a single “embryo” in protoplanetary rings is explained as a result of the action of the 1/1 orbital resonance mechanism. Using the model of wave perturbations of the dust shells of protostars and the model of orbital resonance, a general model of the formation and growth of the “embryos” of planets for disks with masses less than 0.1MS was constructed.
