28978 Ixion           Discovered 2001 May 22 by the Deep Ecliptic Survey.
Ixion tried to win the love of Hera, but Zeus thwarted this by creating the cloud Nephele, which resembled Hera and by whom Ixion fathered the Centaurs. For his crimes Ixion was bound to a wheel that turns forever in the underworld. The name was suggested by E. K. Elliot.
