(16669) Rionuevo Inner Main-belt Asteroid
Discovered on 8 December 1993 by Shoemaker, C. S., Levy, D. H. at Palomar.
In an effort to understand its history stretching back at least 2500 years, Tucson's Rio Nuevo project is preserving and developing the city's heritage. With help from the University of Arizona, the site will benefit all students of the history of the American Southwest.Naming citation (20030501/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
