Abstract Evolution of a system consisting of a great number of bodies that are gravitationally interacting and aggregating in contacts is considered. Body motions take place in the gravitational field of a central massive body (Sun or planet) in the same plane and at the initial time of system evolution orbits of all bodies are circular. It is shown that during evolution of the protoplanetary cloud, ring zones of matter rarefaction and condensation develop. Development of the condensation zones leads to the formation of planets, the most part of which acquire a direct rotation about their axes. In the case under consideration, approximate agreement between the law of planetary distances and that of geometric progression takes place as it is observed in planetary and satellite systems. The formation of the terrestrial planets and Jovian planets has been simulated. The principal numerical results have been obtained through digital simulation of planetary accumulation.
