The **Lagrange Points** are points of equilibrium for small-mass objects under the gravitational influence of two massive orbiting bodies. Mathematically, this involves the solution of the restricted three-body problem. | ![[Lagrange_points_EarthSun.svg\|align:center\|320]] | ![[Lagrangian_points_equipotential.gif\|align:center\|360]] | | ---------------------------------------------------- | ------------------------------------------------------ | For a binary system (like the Sun-Earth system depicted above), there are 5 Lagrange Points. ## Source for Deriving Lagrange Points ![[lagrangepoints.pdf]]
