M. : 2007. - 12 s. A study of the ephemeris tables showed that the speed and radius of the Earth's orbit change monthly, and their extremes do not coincide in aphelion and perihelion. The recalculation of parameters performed for the coincidence of extremes led to a change in the length of the aphelion, perehelion and eccentricity of the orbit. This phenomenon can be explained if we assume that the strength of the gravitational field of the Solar system forms a gravitational lens, which, by deflecting the light and electromagnetic rays of stars, displaces the apparent trajectory of the Earth.
