Ruben Garcia poses a line of questions that can be carried further.
What is the legal definition of a meteorite? I know I cannot sell
oranges labeled as apples.
It is now possible to send an amateur rocket higher than 62 miles;
such happens now at the annual Black Rock NV launches sponsored by

IMHO - This should most likely be called 'Earthite'. A whole new class of rocks
distinct from meteorites, which so far we don't have any of (unless anyone
knows different!?).
Or they could just be known as Tektites, since that is essentially what the
consensus is on Tektites. Though I would
Hi,
According to Alan E. Rubin Jeffrey N. Grossman: A meteorite is a
natural, solid object larger than 10 µm in size, derived from a celestial
body, that was transported by natural means from the body on which it formed
to a region outside the dominant gravitational influence of that body

We call other planetary ejecta meteorites, so

It's a bit of a stretch and model dependent, but in a way, lunar
meteorites may be considered as this type of meteorite.

I have several nice auctions ending this evening, mostly planetary.

OK, so some questions regarding the definition:
1) What would be considered an artificial body?
2) I am 99.9% sure that the word itself refers to the meteorite (as opposed
to the body on which the meteorite lands). Correct?

Hello, list. I was wondering if anyone could tell me if CK class
meteorites are typically attracted to a rare-earth magnet? Thanks.
Michael in so. Cal.

Hi Michael,
Yes they are attracted to rare earth magnets. Some CK meteorites display
free iron.
Thanks,

The answer is yes, Michael. I just held several of my CK meteorites

Yes, the word itself refers to the meteorite (or, more properly, the
meteoroid) and an artificial body would be a spacecraft of some sort.

How do you know that ureilites, aubrites, acapulcoites and the many
achondrite-ung are NOT exploded bits of parent planets destroyed by
alien warfare in our solar system a long time ago? In which case they
would not be meteorites.

Most CK meteorites have no FeNi metal but magnetite instead.
This shows that CK chondrites are highly oxidized. Of course,
magnetite is strongly magnetic! DaG 275 (CK4/5), for example,
is one of those CKs that Peter refers to, as it has trace

The more general question is how we would distinguish a terrestrial
meteorite found on Earth 9as opposed to one found in the lunar regolith).
Unless it was an observed fall, the rock would have to have a fusion crust
for us to notice it in the first place. It would have been exposed to

Hi Bernd,
My experience is that even weathered CK's are strongly attracted to magnets due
to high magnetite content. The Lucerne Valley CK pairing group was recognized
entirely due to the strong magnetic susceptibility.
