The Two-Body Problem,Assume that the masses are spherically symmetrical and homogeneous in concentric layers. So they attract one another as if the mass were concentrated at spherical centers

The Restricted Three-Body Problem,An important particular solution of the three-body problem results when one of the three masses is so small, in comparison to the other two, that its gravitational effects can be neglected. This may be called an . compared with the two finite bodies. This is the restricted three-body problem (Szebehely .), as mentioned in Sect. 1.5

General Perturbations Theory,We have seen the complexity of the problem when more than two gravitating masses are involved. We have seen two methods of determining the orbits, Cowell’s and Encke’s methods. Now, let us look at the basic mathematical description of the perturbation problem.
