• Asteroids occupying two of the Lagrangian points in the orbit of Jupiter, orbiting the Sun 60° ahead of Jupiter (the Greek camp) or behind it (the Trojan camp). Asteroid 624 Hektor is the largest member of the group, apparently measuring about 100 by 300km, and was the first to be discovered. Despite the existence of the two camps, the term Trojan is usually applied to both groups. An asteroid, 1990MB, has also been detected 60° behind Mars and others could exist in the Langrangian points of the orbits of other planets.
