Stationary rotations of a natural celestial body in 2:1 synchronism
Abstract
A set of stationary rotations of a natural celestial body in the gravitational field of the point of attraction is examined under the assumption that the angular velocity of the rotation of the body around its centre of mass is close to the double angular velocity of the orbital motion of the body. It is shown that such stationary rotations exist, usually, only in special cases. It is possibly right for other synchronisms as well.
