Saturn: Observation, Measurement & Evidence

Saturn is a hydrogen-helium gas giant distinguished by its extensive ring system, low average density, rapid rotation, layered atmosphere, and large family of moons. Saturn is central to studies of ring dynamics, giant-planet interiors, atmospheric circulation, satellite interactions, and how disks behave under gravity and collisions.
