The evolution of plane rings of gravitating particles (bodies or material points) moving around the sun is investigated by computer modeling. The algorithm used is investigated. The parameters of the rings of gravitating bodies, which combine during any collisions, correspond to the supply zones of the real planets. The densities of the bodies are close to the present densities of the planets. An analysis of the results obtained shows that the number of planets formed in the supply zone of planets of the terrestrial group would be larger than the actual number of planets if one assumes that all the bodies moved in the same plane and ignores the influence of the drag force of the gas on the motion of the planetesimals and certain other factors. The number of planets formed decreases (possibly to the actual number of planets) if a three-dimensional rather than a plane model is considered.
