The comparative effect of two factors on the translatory motion centres mass Pluto-Charon system is investigated. first important factor non-sphericity shape and gravitational field bodies in system. second gravitation Sun. As a measure influence both we use ratio corresponding perturbing acceleration to main one. caused by mutual Newtonian attraction Pluto Charon. It has been established that ...

This paper presents a set of linearized equations was derived for the motion, relative to an elliptical reference orbit, of an object influenced by J2 perturbation terms. Approximate solution for simulations was used to compare these equations and the linearized keplerian equations to the exact equations. The inclusion of the linearized perturbations in the derived equations increased the high ...
