Lagrange Points, Roche Limits & Hill Spheres: Physical Mechanisms

Lagrange points, Roche limits, and Hill spheres describe three different boundaries in multi-body gravity. These concepts guide observatory placement, explain ring formation and moon disruption, estimate satellite stability, and identify regions where co-orbital populations can survive.

supported

Lagrange points emerge when gravity and the rotating reference frame allow a small body to remain near a repeating geometry.
