5.1.3 Sun, Earth-Moon System


Near side of Moon

A contour plot of the effective potential of a two-body system (the Sun and Earth here) due to gravity and the centrifugal force as viewed from the rotating frame of reference in which Sun and Earth remain stationary. Objects revolving with the same orbital period as the Earth will begin to move according to the contours showing equipotential surfaces. The arrows indicate the gradients of increasing potential around the five Lagrange points toward or away from them, but at the points themselves these forces are balanced. See NASA Wilkinson Microwave Anisotropy Probe for more details.

The three collinear Lagrange points were first discovered by Euler around 1750.[3]
