3:2 Resonance

A 3:2 resonance occurs when two orbiting bodies, like planets or moons, have orbital periods that relate as 3 to 2—for every three orbits of one, the other completes two. This synchronization creates a gravitational pattern that stabilizes their orbits, often leading to regular gravitational interactions. For example, Pluto and Neptune have a 3:2 resonance, preventing close encounters despite crossing paths. This resonance helps maintain a stable cosmic dance, where their motions are harmonized over long timescales, influencing their orbital shapes and positions in predictable, repeating cycles.
