1143 Odysseus is a Jupiter Trojan asteroid that orbits in the L4 Lagrangian point of the Sun-Jupiter system, in the "Greek Camp" of trojan asteroids. It was named after the Greek hero Odysseus Laertiades in Homer's epic poem The Odyssey. It was discovered by Karl Wilhelm Reinmuth in 1930.
As a Jupiter Trojan it is in a very stable orbit. Its closest approach to any major planet will be on 2083-May-04 when it will still be 3.104 AU (464,400,000 km; 288,500,000 mi) from Mars.
Based on IRAS data, Odysseus is 126 km in diameter and is about the 8th largest Jupiter Trojan known.
Photometric observations of this asteroid during 1994 were used to build a light curve showing a rotation period of 10.111 ± 0.004 hours with a brightness variation of 0.22 ± 0.01 magnitude.
