Earth trojan

An Earth trojan is an asteroid that orbits the Sun in the vicinity of the Earth–Sun Lagrange points L4 or L5, thus having an orbit similar to Earth's. Only two Earth trojans have so far been discovere
2010 TK7, one of the two known Earth trojans, is located at the lower right, circled by a small green ring.

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

A gravitational potential contour plot showing Earth's Lagrangian points; L4 and L5 are ahead (above) and behind (below) the planet, respectively. Jupiter's Lagrangian points are similarly situated in its much larger orbit.
Trojan 624 Hektor (indicated) is similar in brightness to dwarf planet Pluto.
