Jupiter-Saturn 5:2 Resonance

Definition

The Jupiter-Saturn 5:2 resonance refers to a mean motion resonance between Jupiter and Saturn, where for every five orbits Jupiter completes around the Sun, Saturn completes two. This gravitational interaction leads to significant effects on the orbits of other celestial bodies in the solar system, particularly in the asteroid belt and among various trans-Neptunian objects.
