(15318) Innsbruck Main-belt Asteroid
Discovered on 24 May 1993 by C. S. Shoemaker at Palomar.
Innsbruck, capital of Tyrol in the heart of the Alps on the great route from Italy, has a history deeply connected with the Hapsburg dynasty. This city in western Austria lays claim to the 1936 Nobel prizewinner V. F. Hess and hosted two winter Olympic games. The name was suggested by P. Teutsch and R. Weinberger.Naming citation (20010309/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
