83982 Crantor           Discovered 2002 Apr. 12 by the Near-Earth Asteroid Tracking (NEAT) project at Palomar.
Crantor was a Lapith who was killed by the centaur Demoleon in the battle between the Lapiths and the Centaurs. Demoleon fatally wounded Crantor after he tore off Crantor's chest and left shoulder with a tree trunk that Demoleon had thrown at Theseus, who ducked out of the way.
