17493 Wildcat           Discovered 1991 Dec. 31 by C. S. Shoemaker and D. H. Levy at Palomar.
The University of Arizona (whose athletic symbol is a wildcat) has contributed to astronomy and planetary sciences almost from its founding in 1885. Today the university remains in the forefront of astronomical research, discovery and in astronomical instrument development.
