  We consider the Earth-Moon planar circular restricted three body problem and
present a proof of the existence orbits, which approach arbitrarily close to
one of the primary masses, and at the same time after each approach they move
away from the mass to a prescribed distance. In other words the orbits
oscillate between being arbitrarily close to collision and away from it. We
achieve our goal with the use of topological tools combined with rigorous
interval computations. We use the Levi-Civita regularization and validate that
the dynamics in the regularized coordinates leads to a good topological
alignment between various sets. We then perform shadowing arguments that this
leads to the required dynamics in the original coordinates of the system.
