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.
In astronomy, a trojan is a small celestial body (mostly asteroids) that shares the orbit of a larger body, remaining in a stable orbit approximately 60° ahead of or behind the main body near one of its Lagrangian points L 4 and L 5. Trojans can share the orbits of planets or of large moons. Trojans are one type of co-orbital object.
An Earth-based search for L 5 objects was conducted in 1994, covering 0.35 square degrees of sky, under poor observing conditions. [5] That search failed to detect any objects: "The limiting sensitivity of this search was magnitude ~22.8, corresponding to C-type asteroids ~350 m in diameter, or S-type asteroids ~175 m in diameter."

The Trojan asteroids, which borrow their name from Greek mythology, orbit the sun in two swarms — one that’s ahead of Jupiter, the largest planet in our solar system, and a second one that ...
(706765) 2010 TK 7 (provisional designation 2010 TK 7) is a sub-kilometer Near-Earth asteroid and the first Earth trojan discovered; it precedes Earth in its orbit around the Sun. [4] [5] Trojan objects are most easily conceived as orbiting at a Lagrangian point, a dynamically stable location (where the combined gravitational force acts through ...

Astronomers spotted a possible “sibling” planet that shares the orbit of another exoplanet in a system located 370 light-years away.
This is a list of Jupiter trojans that lie in the Greek camp, an elongated curved region around the leading Lagrangian point (L 4), 60° ahead of Jupiter in its orbit.. All the asteroids at Jupiter's L 4 point have names corresponding to participants on the Greek side of the Trojan War, except for 624 Hektor, which was named before this naming convention was instituted.
