Planetary ring systems

This session is open for discussions about rings around Jupiter, Saturn, Uranus, Neptune and small outer-solar-system bodies. Theoretical and observational studies of ring morphology, dynamics, composition, origin, evolution, and interactions with nearby moons are all topics of interest. Contributions reporting on the latest results from the Cassini mission and from TNO and Centaur observations are particularly welcome.
