A model of planetary evolution is proposed. The evolution of a photoplanetary gas-dust cloud, laminarly rotating around the Sun in the boundaries of the present planetary system, results in the formation of solid planetesimals grouped in concentric zones of growing embryo planets. The growth of terrestrial planets takes about 100 million years, several times longer than the period of dissipation of gas from the inner parts of the protoplanetary cloud. The formation of giant planets is a two-stage process: the formation of nuclei from the solid material with mass 2 to 3 Earth masses in 10 to 100 million years, then the gaseous accretion on nuclei in 100,000 to 1 million years. The origin of satellites is a process accompanying the growth of planets on the most active stage, via circumplanetary swarms for terrestrial planets and accretional disks for giants.
