Object guide
Saturn is a gas giant best known for its spectacular ring system made of ice and rock. It has dozens of moons including Titan and Enceladus, which are high-priority targets for astrobiology. Saturn is approximately 116,464 km across.
How to observe Saturn
Saturn is best observed near opposition or greatest elongation as appropriate; steady seeing and repeated short observations reveal more than excessive magnification.
