1988 PB1. Discovered 1988 Aug. 14 by C. S. Shoemaker and E. M. Shoemaker at Palomar.

Named for the huge, stalwart son of the Trojan counselor Antenor {see planet (2207)} and brother of Agenor {see planet (1873)}. During the battle near the Greek encampment, Iphidamas thrust his spear into Agamemnon {see planet (911)}, who was saved by his war belt. Pulling the spear toward himself, Agamemnon then killed Iphidamas with a sword stroke to the neck. (M 18465)
