(6362) Tunis is an asteroid of the main outer belt discovered on May 19, 1979 by the Danish astronomer Richard Martin West at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809). There had already been an unconfirmed sighting of the asteroid on January 25, 1971 with the provisional designation 1971 BC 1 at the Crimean Observatory in Nautschnyj .
The mean diameter of (6362) Tunis is 39.58 (± 3.5) km, the surface is with an albedo of 0.0373 (± 0.008) darker than any planetary surface in the solar system on average.
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel near (6362) Tunis also assumed a dark surface, so it could be roughly seen to act around a C asteroid .
(6362) Tunis was named after Tunis , the capital of Tunisia, on May 9, 2001 at the suggestion of Richard Martin West . On November 7, 2001, Richard Martin West received the Order of Grand Officier de l'Ordre de la République from the Tunisian President Zine el-Abidine Ben Ali for being named .
