Lunar meteorites are among the most popular and sought-after meteorites, the total weight of lunar meteorites ever found is incredibly low compared to usual meteorites. NWA 4881 was found in the Sahara desert and classified as a feldspathic granulitic breccia, similar samples of which had been recovered at most Apollo lunar highland sites.

History: Found in 2005 in the Sahara Desert.

Physical characteristics: A single, broken, irregular conical stone (606g) partially covered by translucent, pale greenish fusion crust and with a pale grey-brown interior.

Petrography: (A. Irving and S. Kuehner, UWS) Fine grained recrystallized breccia composed of larger plagioclase grains (converted partially to maskelynite) poikilitically enclosing very small grains (mostly 30-80 microns) of low-Ca pyroxenes, olivine, Ti-chromite, ilmenite, troilite and metal.

Mineral compositions and geochemistry: Olivine (Fa40.4-58.8, FeO/MnO = 91-100), plagioclase (An96.1-98Or<0.1), pigeonite (Fs32.0-64.5Wo9.5-13.1, FeO/MnO = 51.1-62).

Classification: Achondrite (lunar, granulitic breccia). This stone is paired with Northwest Africa 3163 (Irving et al., 2006) and Northwest Africa 4483; in combination these specimens evidently represent naturally broken pieces from a crusted lunar meteorite weighing at least 2448g.

Specimens: A total of 20g of sample and one polished mount are on deposit at UWS.

How do we know it is a real piece of the Moon?
The moon is constantly hit by meteorites itself and with no atmosphere and little gravity the larger impacts will eject lunar rocks into space. After this impact, this meteorite will eventually be brought down to Earth by the Earth's gravitational pull. Scientists and universities all around the world examine meteorites and compare them with known lunar material, e.g. samples collected during the Apollo missions. The composition of gases and isotopes found is so unique that they can say for sure the material originated from the moon.
