For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

134329 Cycnos           Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Cycnos, an ally of Priam, was a son of Poseidon by a nymph. His body was firm as iron; he was invulnerable. Achilles tried three times to kill him with his spear, but without success. He then strangled him after Cycnos stumbled over a stone.
