Discovery and naming[edit]

Rhadamanthus was discovered on 17 April 1999 by the Deep Ecliptic Survey.

Rhadamanthus is named after the Greek mythological figure. The name was announced in the circular of the Minor Planet Center of 24 July 2002, which stated "Rhadamanthus was a son of Zeus and Europa. Because of his just and upright life, after death he was appointed a judge of the dead and the ruler of Elysium, a blissfully beautiful area of the Underworld where those favored by the gods spent their life after death. The name was suggested by E. K. Elliot."[5]
