The influence of the evolution of the node of an orbit on the rotation of a celestial body in 2:1 resonance
Abstract
A set of stationary rotations of a dynamically symmetrical celestial body is considered under the assumption that the speed of its rotation is about double the speed of its orbital motion, with an account for the gravitational and tidal torques, as well as for the evolution of the orbit. The stabilizing influence of the effect of secular rotation of the orbit's node on resonant rotations by small values of the angle between the vector of the kinetical moment of the body and the normal to the orbit's plane is discovered.
