5254 Ulysses is a large Jupiter trojan from the Greek camp, approximately in diameter. It was discovered on 7 November 1986, by Belgian astronomer Eric Elst at the Haute-Provence Observatory in Saint-Michel-l'Observatoire near Marseille, southeastern France. The assumed C-type asteroid belongs to the 40 largest Jupiter trojans and has a longer-than-average rotation period of 28.72 hours. It was later named after "Ulysses", the Latinized name of the legendary hero from Greek mythology, Odysseus.
