Titan / Tethys

Saturn's moon Tethys, with its stark white icy surface, peeps out from behind the larger, hazy, colorful Titan in this Cassini view of the two moons. Saturn's rings lie between the two. 

The north polar hood can be seen on Titan appearing as a detached layer at the top of the moon here. Ithaca Chasma, a long series of scarps or cliffs on Tethys, faintly can be seen running north-south on that moon. This view looks toward the anti-Saturn side of Titan (3200 miles, 5150 kilometers across) and the Saturn-facing side of Tethys (660 miles, 1062 kilometers across). This view looks toward the northern, sunlit side of the rings from just above the ring plane. 

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 May 21, 2011 at a distance of approximately 1.4 million miles (2.3 million kilometers) from Titan and 2.4 million miles (3.8 million kilometers) from Tethys. Image scale is 9 miles (14 kilometers) per pixel on Titan and 18 miles (27 kilometers) per pixel on Tethys.
