Original caption:"Titan, the Saturn's largest moon and Mimas - in the foreground - are seen together in this view from Cassini.
Titan's gravity is weaker than Earth's, so the moon's atmosphere is quite extended - a "quality" that is very well hinted at in this view.

Part of Mimas' dark side is illuminated by reflected light from nearby Saturn.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 3, 2005, at a distance of approx. 3,6 MKM (about 2,2 MMs) from Titan and 2,5 MKM (1,6 MMs) from Mimas.
Both moons are seen at a phase angle of 110°.
The image scale is 22 Km (roughly 14 miles) per pixel on Titan and 15 Km (about 9 miles) per pixel on Mimas".
