Considering the Motion of the Elastic Lunar Pole

In connection with the development of the Japanese project ILOM on the study of the rotational motion of the Moon using a telescope mounted on the surface of the moon (near the north pole), there are increased demands on the accuracy of the analytical and numerical description of physical librations. In particular, studies of the influence of the elastic properties of the Moon on its rotational motion with the high-precision description of its orbital motion and taking into account the resonant nature of motion are of a significant importance. In this work it is shown that the elastic properties of the Moon result in extending of the oscillations period of its pole by 8.0 days.
