Jupiter trojan - Wikipedia
The Jupiter trojans, commonly called trojan asteroids or simply trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun. Relative to Jupiter, each trojan librates around one of Jupiter's stable Lagrange points: either L 4, existing 60° ahead of the planet in its orbit, or L 5, 60° behind.
