Lagrange Point 2, commonly referred to as L2, is one of the five special points in the orbital configuration of two massive bodies, such as the Earth and the Sun, where a smaller object can maintain a stable position relative to the two larger bodies. These points were mathematically described by the French-Italian mathematician Joseph-Louis Lagrange in 1772. L2 is located on the line defined by the two massive bodies, beyond the smaller of the two.
