(8125) Tyndareus Jupiter Trojan
Discovered on 30 September 1973 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T. at Palomar.
Named for a king of Sparta, father of Clytemnestra and Helena. Often it is said, however, that Tyndareus was the foster-father of Helena, because Helena is generally considered to have been the daughter of Zeus and Leda.Naming citation (19980411/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
