Query: Orbital stability of the restricted three body problem in General
  Relativity   We consider the problem of orbital stability of the motion of a test particle
in the restricted three-body problem, by using the orbital moment and its time
derivative. We show that it is possible to get some insight into the stability
properties of the motion of test particles, without knowing the exact solutions
of the motion equations.
