Abstract

On the basis of the analytic theory of longitude libration of Mercury (in the elliptical orbit) and the data of determination of values of the angular velocity of Mercury rotation obtained using high-precision complex method of ground radar tracking, the amplitude, phase, and period of free libration and amplitudes of five fundamental harmonics (annual, semi-annual, third annual, …) of forced librations in longitude of the planet are determined.
