Hi Steve,

This has been debated MANY times on the list in the past and to my knowledge
there has never been a generally accepted term. But it's not just a future
problem for "when we have people there". We already have approved meteorites
that we have discovered on other planetary bodies such as Meridiani Planum
(Mars) and Hadley Rille (Moon). I guess these are officially called
meteorites too but you could say 'meteorite found on Mars'. It might start
getting confusing if we find Lunars on Mars! ;-)

On 20th March this year, Jeff Grossman wrote the following:

As to the question of "is it a meteorite?", not according to the Rubin
and Grossman definition (Meteorite! 4 (3), p. 24-25, 1998):

"A meteorite is a natural solid object that was transported by natural
means from the body on which it formed to a region outside the dominant
gravitational influence of that body and was later
accreted by a natural body larger than itself."

I'm not sure if any of this really answers your question but it's definitely
something that has been considered by many and I'm sure others will have
their own opinions and interpretations.

Cheers,

>From the other Jeff
