... kinetic yield -- See impact energy. Lagrangian points -- Discovered by Italian-French mathematician Joseph Louis Lagrange, the Lagrangian points mark positions where the gravitational pull of two large, mutually orbiting masses precisely equals the centripetal force required to keep a small body there rotating at the same angular speed as the massive ones.
