Mean Motion Resonance

Mean motion resonance occurs when two celestial bodies, such as planets or moons, have orbital periods that are in a simple whole-number ratio (like 2:1 or 3:2). This means that they align in their orbits at regular intervals, often leading to gravitational influences that repeat consistently. These resonances can stabilize their orbits or, in some cases, create orbital variations. It's a natural outcome of gravitational interaction over time, demonstrating a harmonious relationship that maintains the bodies’ regular patterns despite their mutual pulls.
