We extend the analysis, started in a previous work [1], concerning the formation of lunar
impact craters due to low-energy trajectories.  First, we adopt the Circular Restricted Three-
Body Problem and consider different choices of initial conditions inside the stable invariant
manifold associated with the central invariant one in the neighborhood of the L2 equilibrium
point in the Earth–Moon system.  Then we move to the Bicircular Restricted Four-
Body Problem to study the effect of the Sun on the distribution of impacts on the Moon’s
surface
