Jupiter trojan

Maximilian Franz Joseph Cornelius Wolf (1890)—the discoverer of the first trojan

A gravitational potential contour plot showing Earth's Lagrangian points; L4 and L5 are above and below the planet, respectively. Jupiter's Lagrangian points are similarly situated in its much larger orbit.

The Jupiter trojans, commonly called Trojan asteroids or just Trojans, are a large group of asteroids that share the orbit of the planet Jupiter around the Sun. Relative to Jupiter, each trojan librates around one of Jupiter's two stable Lagrangian points, L₄, lying 60° ahead of the planet in its orbit, and L₅, 60° behind. Jupiter trojans are distributed in two elongated, curved regions around these Lagrangian points with an average semi-major axis of about 5.2 AU.
