We treat the circular and elliptic restricted three-body problems in inertialframes as periodically forced Kepler problems with additional singularities andexplain that in this setting the main result of [4] is applicable. Thisguarantees the existence of an arbitrary large number of generalized periodicorbits (periodic orbits with possible double collisions regularized) providedthe mass ratio of the primaries is small enough.
