Celestial Mechanics: Three-Body Problem

This lecture covers the dynamics of three-body systems in celestial mechanics, focusing on the interactions between celestial bodies and the concept of Lagrange points. The instructor explains the analytical and numerical approaches to studying the stability and equilibrium points in such systems, including the effects of inertia and gravitational forces. Various scenarios, such as near-collisions and the formation of double stars, are discussed to illustrate the complexities of three-body dynamics.
