Is the Kaidun meteorite a Martian meteorite?
- In March 2004 it was suggested that the unique Kaidun meteorite, which landed in Yemen on Decem, may have originated on the Martian moon of Phobos. Because Phobos has similarities to C-type asteroids and because the Kaidun meteorite is a carbonaceous chondrite, Kaidun is not a Martian meteorite in the strict sense.
