ABOUT NWA 4664 VESTA Meteorite
Name: Northwest Africa 4664
Abbreviation: NWA 4664 
Observed fall: No
Year found: 2006
Country: Algeria 
Mass: help 20 kg
Find: 2006
History and Physical characteristics: Many stones that weigh ~20 kg were purchased in Rissani, Morocco, in July 2006 by A. Aaronson and are part of a large strewn field in which at least 30 kg have been recovered.
Petrography: (T. Bunch and J. Wittke, NAU) A moderately shocked diogenite cataclastic breccia. Samples range from very matrix-rich to those that are matrix-poor and are composed of closely packed clasts. Mineral modes (vol%): orthopyroxene = 92, olivine = 4, plagioclase = 2, augite = 2, chromite and FeS = 1. Trace amounts of silica and metal are also present. The sample has at least two lithologies: one contains orthopyroxene with lowest FeO and without olivine; the other contains olivine with slightly more FeO-rich orthopyroxene. Orthopyroxene grains show minor amounts of shock lamellae and well-developed undulatory extinction. Plagioclase is partially isotropic.
Mineral compositions and Geochemistry: Orthopyroxene (Fs17.8-23Wo1.1-2.8; FeO/MnO = 30-37), olivine (Fa24.1-32.6; FeO/MnO = 52-56), plagioclase (An79), chromite (Cr/(Cr + Al) = 0.67).
Classification: Achondrite (diogenite, polymict breccia); moderate shock, minimal weathering. Most likely paired with NWA 4473.
Type sample: A 34 g sample is on deposit at NAU. Aaronson holds the main mass.
Vesta, minor-planet designation 4 Vesta, is one of the largest objects in the asteroid belt, with a mean diameter of 525 kilometres (326 mi). It was discovered by the German astronomer Heinrich Wilhelm Olbers on 29 March 1807 and is named after Vesta, the virgin goddess of home and hearth from Roman mythology. Vesta is the second-most-massive and second-largest body in the asteroid belt after the dwarf planet Ceres, and it contributes an estimated 9% of the mass of the asteroid belt. It is slightly larger than Pallas, though significantly more massive. Vesta is the only known remaining rocky protoplanet (with a differentiated interior) of the kind that formed the terrestrial planets. Numerous fragments of Vesta were ejected by collisions one and two billion years ago that left two enormous craters occupying much of Vesta's southern hemisphere. Debris from these events has fallen to Earth as howardite–eucrite–diogenite (HED) meteorites, which have been a rich source of information about Vesta. Vesta is the brightest asteroid visible from Earth. Its maximum distance from the Sun is slightly greater than the minimum distance of Ceres from the Sun, though its orbit lies entirely within that of Ceres. NASA's Dawn spacecraft entered orbit around Vesta on 16 July 2011 for a one-year exploration and left orbit on 5 September 2012 en route to its final destination, Ceres. Researchers continue to examine data collected by Dawn for additional insights into the formation and history of Vesta.
