Hello Pekka,=20

Perhaps Copernicus didn't go far enough... :)

If you want to go into the details, you will also find at the moment it is=20
also more correct to call the Moon-Earth System is a binary Planetary system=
,=20
and Luna a Planetoid, not a "Meteoroid", so we are just the third "rocks" in=
=20
plural from the Sun. So a meteorite from the Moon is no more significant th=
an a=20
handful of dirt from Finland sent to Australia, although I guess Suomen Post=
i=20
Oy's rate might be a bit higher.

I remind you that the oldest of a few Apollo sample Moon rocks have been=20
dated to nearly 4.5 billion years old, and Allende is considered to be 4.56=20
billion years old.

On the other hand following the logic we can consider other protoplanetary=20
impact events, and we are mostly part of the Solar nebula, so we would all b=
e=20
Solar meteoroids, and that includes that freckled runt, Jupiter...

Anyway, you are right, without the phases of the Moon it would be unfortunat=
e=20
to have it land in the back yard...
