In astronomy, the adjective 'Trojan' refers to asteroids or moons that share the same orbit as a larger planet or moon, but does not collide because it orbits within one of the two Lagrangian points of stability, ''L₄'' and ''L₅'', which results in it always orbiting 60° ahead of or behind the larger object.
The term originally referred to asteroids orbiting in Jupiter's Lagrangian points. Now, other objects have been found orbiting in the Lagrangian points of other planets. In addition, Trojan moons orbit in the Lagrangian points of some of Saturn's larger moons.
