(43793) Mackey Main-belt Asteroid
Discovered on 13 November 1990 by Shoemaker, C. S., Levy, D. H. at Palomar.
Lance Mackey (b. 1970), with his canine athletes, is the first musher to win North America's two premier long-distance sled-dog races back-to-back, the 1000-mile Yukon Quest and the 1100-mile Iditarod. His 2007 triumphs are testimonial to his courage, toughness and determination as a cancer survivor.Naming citation (20070601/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
