Diogenites are composed of igneous rocks of plutonic origin, having solidified slowly enough deep within Vesta's crust to form crystals which are larger than in the eucrites. These crystals are primarily magnesium-rich orthopyroxene, with small amounts of plagioclase and olivine.

The proposed source of diogenites is the Rheasilvia, on Vesta (the largest asteroid of the solar system). It is estimated that the impact responsible excavated about 1% of the volume of Vesta, and it is likely that the Vesta family and V-type asteroids are the products of this collision, as well as diogenite meteorite family.


Following tremendous explosions on June 27, 1931 eard at more than 70km around, numerous fragments of an unusually green colour meteorite were found lying on the desert floor near the city of Foum Tataouine (Tunisia) by French soldiers of a local military camp. The meteorite fall event and composition was fully studied by the famous mineralogist Lacroix, then presented to the "Académie des Sciences" in Paris (1934). The full report (in French) is still available.

Tatahouine meteorite is a pyroxenite mineralogicaly speaking, compositionally dominated by orthopyroxene (~90 vol%). Unlike most other diogenites, Tatahouine's dominant pyroxene is composed mostly of numerous large single, usually seemingly unfragmented crystals of orthopyroxene.

Fun fact, a part of the Star Wars trilogy was shooted in the desert near Tatahouine by Georges Lucas in the late 70. He choosed to name the desertic planet... Tatooine in reference to this place.

Fragment of the meteorite as found, sent with certificate.
