We are sometimes wrongly told that this abominable zero-velocity potential diagram show areas that are "bound" or "unbound" to Lagrange points, but it does not and ...

This is in contrast to the actual case when a body is tidally locked, such as our moon. The moon rotates once per (lunar) month at exactly the same rate as it orbits ...

NASA runs the Meteoroid Environment Office which in part monitors lunar impacts. They state; The lunar impact rate is very uncertain because observations for objects in this mass range ...
