Object guide
Titan is Saturn's largest moon with a dense nitrogen-rich atmosphere and hydrocarbon lakes on its surface. Complex organic chemistry in its atmosphere and surface makes Titan a high-priority target for astrobiology. Titan is approximately 5,149.4 km across.
How to observe Titan
Titan is resolved as a separate world mainly through imaging or spacecraft data; visually, its relationship to saturn is the key observing context.
