(8405) Asbolus Centaur
Discovered on 5 April 1995 by Spacewatch at Kitt Peak.
The “black one”, Asbolus was the centaur who supposedly made forecasts from the flight formations of birds. He caused the battle between the centaurs and Heracles and thus was indirectly responsible for the deaths of Pholus and Chiron.Naming citation (19990928/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
