Lagrange Point
The Lagrange points are points of equilibrium for small-mass objects under the gravitational influence of two massive orbiting bodies. For any combination of two orbital bodies, there are five Lagrange points, all in the orbital plane of the two large bodies. L1, L2, and L3 are on the line through the centers of the two large bodies, while L4 and L5 each act as the third vertex of an equilateral triangle formed with the centers of the two large bodies.
Due to the natural stability of L4 and L5, it is common for natural objects to be found orbiting in those Lagrange points of planetary systems. Objects that inhabit those points are generically referred to as 'trojans' or 'trojan asteroids'.
