The partially eroded crater is located to the southeast of Emi Koussi on the Tibesti Massif in Chad. The impact nature of the crater was confimed in 1992 when a team of French investigators identified shocked minerals at the site. It has been proposed, although not confirmed, that Aorounga (south) is one of a chain of craters. Two craters to the northeast (Aorounga central and Aorounga north) were detected in radar images of the area taken by the Spaceborne Imaging Radar C/X-band Synthetic Aperature Radar (SIR-C/X-
SAR) on the Space Shuttle Endeavour in April and October of 1994. The dark streaks overlaying the crater are valleys carved out by thousands of years of wind erosion.
