Orbital resonance is a phenomenon in celestial mechanics where two orbiting bodies exert periodic gravitational forces on each other, causing their orbits to become synchronized. This can lead to stable patterns of motion and create interesting dynamics in the solar system and other planetary systems. Orbital resonance plays a key role in the formation and evolution of planetary systems, moons, and other celestial bodies. Scientists study orbital resonance to understand the behavior of objects in space and to make predictions about their future movements.
