In astrodynamics, a Lagrange point is an equilibrium point of a small object (such as a satellite) experiencing the gravitational pull of two large objects (such as the Sun and Earth). Mathematically, Lagrange points represent positions where the gravitational pull of two large masses precisely balances the centripetal force on a much lighter body. It arises in solutions of the restricted three-body problem, in which two bodies are far more massive than the third.


This Demonstration approximates the rotation of the Lagrange points , , , and and the Earth around the Sun, treating them as a rigid body.
