26871 Tanezrouft           Discovered 1993 Oct. 9 by E. W. Elst at the European Southern Observatory.
The Tanezrouft Basin, a part of the Sahara Desert, lies just above the Tropic of Cancer, about 750 miles south of Algiers. An especially parched land with annual rainfall less than 0.2 inches, it is hyperarid, with very high temperatures and scarcity of vegetation. There are no permanent residents here, only occasional Tuareg nomads.
