摘要

The main aim of the present work is to study the positions of the equilibria points and their stability in the frame work of satellite approxima-tion. The significant implication is that the motion around these points is unstable in the linear sense. The principle of angular momentum conservation is used as a tool to reduce the degree of freedom of the dynamical systems of equations. The positions of the relative equilibria are explicitly found as well as necessary and sufficient conditions for stable motion in the linear sense axe stated.
