(Phys.org) -- The Cassini spacecraft watches a pair of Saturn's moons, showing the hazy orb of giant Titan beyond smaller Tethys. This view looks toward the Saturn-facing sides of Titan (3,200 miles, or 5,150 kilometers across) and Tethys (660 miles, or 1,062 kilometers across).

The image was taken in visible green light with the narrow-angle camera on Oct. 18, 2010. The view was obtained at a distance of approximately 1.6 million miles (2.5 million kilometers) from and at a Sun-Titan-spacecraft, or phase, angle of 55 degrees.

The view was obtained at a distance of approximately 930,000 miles (1.5 million kilometers) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 55 degrees. Image scale is 15 kilometers (9 miles) per pixel on Titan and 6 miles (9 kilometers) per pixel on Tethys.
