Orbital mechanics
The Restricted Three-Body Problem
The motion of a small body under the gravity of two larger ones orbiting each other. It has no general closed-form solution, yet its study yields the Lagrange points, the concept of orbital stability, and much of modern spacecraft trajectory design.
