Circumsatellital rings maintain long-term orbital stability around Solar System moons that possess a lower Roche-to-Hill radius, showing minimal variations in orbital parameters.
Numerical N-body simulations evaluate the gravitational perturbations from host planets and neighboring companions, tracking the induced eccentricity and ring gaps.
Highlights that non-gravitational phenomena like stellar radiation and magnetospheric plasma likely drive ring decay, warranting dedicated future investigations.

Implication

Numerical simulation reveals that circumsatellital rings remain dynamically stable around major moons, indicating non-gravitational forces drive their modern absence.
