In this paper the movement of the artificial satellites of the Earth on low orbits is analyzed which are subject to resistance of a rarefied atmosphere. Temperature and density of terrestrial atmosphere at height of 200-800 km vary over wide range under influence of external conditions. The changes of solar activity are compared to variations of satellite braking (atmospheric drag). In spite of the fact that unequivocal dependence of the atmosphere density behavior from the considered physical factors of solar activity is not present, the attempt is done to find the characteristic periods in these processes. Some periods of fluctuation of an atmosphere density are revealed which can be harmonics of the basic period close to 27 days. Fluctuations of density with the period about 27 days have two close components, which reason is not quite clear. Probably, they are caused by rotation of the Sun and lunar tidal wave in the Earth's atmosphere.
