(13475) Orestes Jupiter Trojan
Discovered on 19 September 1973 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T. at Palomar.
Orestes, a son of Agamemnon, was a child at the time of the murder of his father. Electra brought him to his uncle, where he lived together with his cousin Pylades. To avenge his father, Orestes killed Aegisthus and Clytaemnestra. The Erinyen persecuted him until he was absolved by the special jury at the Areopagus.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
