- Lagrangian point
- one of the solutions to the three-body problem discovered by the eighteenth century French mathematician Lagrange. The two stable Lagrangian points, L-4 and L-5, lie in the orbit of the primary body, leading and trailing it by a 60-degree arc. Jupiter's trojan asteroids can be found orbiting around the Jupiter-Sun L4 & L5 points.
