A Lunar meteorite is a meteorite that is known to have originated on the Moon. In January 1982, John Schutt, leading an expedition in Antarctica for the ANSMET program, found a meteorite that he recognized to be unusual. Shortly thereafter, the meteorite now called Allan Hills 81005 was sent to Washington, DC, where Smithsonian Institution geochemist Brian Mason recognized that the sample was unlike any other known meteorite and resembled some rocks brought back from the Moon by the Apollo program. Several years later, Japanese scientists recognized that they had also collected a lunar meteorite, Yamato 791197, during the 1979 field season in Antarctica. About 112 (as of February, 2008) other lunar meteorites have subsequently been discovered, perhaps representing 50 separate meteorite falls (i.e., many of the stones are paired" fragments of the same meteoroid). The total mass is more than 46 kg. All lunar meteorites have been found in deserts most have been found in Antarctica, northern Africa, and the Sultanate of Oman. None have yet been found in North America, South America, or Europe."
