Aorounga is an eroded meteorite impact crater in Chad, Africa. The exposed remnant of the crater is 12.6 km in diameter and its age is estimated to be less than 345 million years (Carboniferous or younger). [Aorounga at Earth Impact Database [http://www.unb.ca/passc/ImpactDatabase/images/aorounga.htm] ]

The crater is accompanied by two nearby circular features revealed by Space Shuttle SIR-C radar. These may be related impact craters, and if correct, Aorounga may be part of a crater chain. On the assumption that this hypothesis is correct, the exposed Aorounga crater is sometimes referred to as Aorounga South.
