Saturn’s largest and second-largest moons

The Cassini spacecraft captured this image on June 16, 2011. These are two of Saturn’s moons – the largest moon Titan and second-largest moon Rhea.

Saturn’s largest and second-largest moons, Titan and Rhea, appear to be stacked on top of each other in this true-color scene from NASA’s Cassini spacecraft.

Titan’s north polar hood can be seen. It’s 3,200 miles (5,150 kilometers) across. The hood appears as a detached layer at the top of the moon on the top right.

This view looks toward the Saturn-facing side of Rhea (949 miles or 1528 kilometers across). North on Rhea is up and rotated 35 degrees to the right.

Images taken using red, green and blue spectral filters were combined to create this natural-color view. The images were acquired with the Cassini spacecraft narrow-angle camera on June 16, 2011, at a distance of approximately 1.1 million miles (1.8 million kilometers) from Rhea and 1.5 million miles (2.5 million kilometers) from Titan. Image scale is 7 miles (11 kilometers) per pixel on Rhea and 9 miles (15 kilometers) on Titan.
