17314 Aisakos           Discovered 1971 Mar. 25 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Aisakos, a son of Priam from his first marriage, was a seer, as had also been his maternal grandfather, Merops. Aisakos said that Hecuba's future son would bring disaster to Troy.
