5254 Ulysses (1986 VG1) is a Jupiter Trojan discovered on November 7, 1986 by E. W. Elst at Haute-Provence Observatory.
Photometric observations of this asteroid during 1994 were used to build a light curve showing a rotation period of 28.72 ± 0.08 hours with a brightness variation of 0.32 ± 0.01 magnitude.[2]
In popular culture
- In Ace Combat Infinity, the asteroid is known as Ulysses 1986VG1 and it's portrayed as Jupiter's moon rather than a Trojan. Its collision with another, previously undiscovered asteroid named Polyphemus has resulted in a swarm of meteoroids that have caused a catastrophic impact event on the Earth.
