Space rock on my mantlepiece

[M Holmes]

Another thought on why Lunar meteorites may be relatively rare:

With impacts of a certain size, chunks of the Moon might indeed be
imparted lunar escape velocity, but might then go into Earth orbity
rather than a solar orbit which Earth could later intercept. Effectively
to hit Earth, such impacts have to produce chunks of the Moon which
escape the Earth/Moon system altogether. That problem doesn't exists
where Mars is concerned. So the question becomes whether the escape
velocity required for solar orbit from the surface of the Moon is
greater than that from the surface of Mars.
