I keep up with both Martian and Lunar meteorite counts because I
collect both types. Your information that there are 5 or 6 times
more Martian meteorites known than lunar ones is very
inaccurate.If fact, currently the number is almost equal, with
33 Lunar meteorites known and 32 Martian meteorites. That
changes the picture considerably.

FYI, Lunar meteorites tend to be smaller than Martian
meteorites, but there are many different factors that may
account for that, including a generally greater friability or
brittleness of lunaites, perhaps due to their formation on a
body of much lower gravitation than Mars.

For details and excellent photos of many of them, go to my
friend Norbert Klassen's two excellent webpages:
