Abstract:
A particle steady motions in vicinity of dynamically symmetric precessing rigid body are studied
in assumption that the body gravitational field is modeled as two centers gravitational field.
The particle motion equations are written as two-parametric generalization for equations of
Restricted Circular Problem of Three Bodies (RCP3B). Existence and number of the particle
relative equilibria in the plane passing through the body axis of dynamical symmetry and through
the vector of angular momentum are established. These equilibria called Coplanar Libration
Points (CLP) are analogs of Eulerian Libration Points in RCP3B. Stability of CLP is studied for
the first approximation in assumption that attracting centers have equal masses.
Keywords:problem of three bodies, libration points, stability, steady motions, asteroid.
