My notes from Dr. Frederick D. Leonard's Meteoritics 118 class which I took
at UCLA (I believe in1962) say:
A meteorite is any object of sub-planetary mass which has landed on Earth,
or some other astronomical body, and still retains its original cosmic
characteristics.
(Little did he know that someday we would photograph meteorites residing on
the surface of Mars!)

Pete sometime let me tell you about the First Church of the Navelites..
but to your question
They would be called meteorites until identified as originating from the
Earth--then the debate is opened up again.
Recently someone at NASA or in the IAU stated the new definition of
meteorite includes any rocky object falling onto the surface of any planet
should be regarded as a meteorite (my translation)
I recently read a calculation of the number of Earth originating rocks
gone to meteorites on the moon and on Mars and it was a fairly high number
within the realistic realm of being identified as such.
A further subset of missing nomenclature is what to call returning non
tektite ejecta that may have orbited a while and get returned much later.
The Reis impactor is a candidate for having been able to eject rocks into
orbit. As I've mentioned it before, it hurled some multi-ton limestone
boulders over 60 miles up a mountain side in Austria.
A meteorite could not eject material into space from earth but an asteroid
sized impactor most certainly has in the past. That is the physics don't
prohibit it.

We have the Martian type meteorite,
and we have the
Lunar meteorite and last, the asteroid 4Vesta meteorite.
These we know where they come from.
Now the question---given enough energy, can a meteorite
hit earth and eject debris which (maybe) land on the moon
or Mars? What would we call such a meteorite---Earthoid,
or maybe Earthite?
Just contemplating my navel here.
Pete
