Composition
Dione contains large amounts of water-ice, which makes up about two-thirds of her mass. The rest is probably a dense, silicate core.

Orbit - Rotation
Dione orbits rather close to Saturnball. She maintains a 1:2 mean-motion resonance with her brother, Enceladusball, which maintains the latter's slight eccentricity.
