(17365) Thymbraeus Jupiter Trojan

Discovered on 7 November 1978 by Helin, E. F., Bus, S. J. at Palomar.

Thymbraeus was one of the two sons of Laocoön who was killed by sea serpents sent to punish the father for attempting to warn the Trojans about the danger of the wooden horse left by the Greeks. The scene is immortalized in an ancient sculpture, the Gruppo del Laocoonte on display in the Vatican.Naming citation (WGSBN Bull. 3, #3, 11), IAU / Minor Planet Center, via NASA/JPL
