Cassini watches a pair of Saturn's moons, showing the hazy orb of giant Titan beyond smaller Tethys. In the foreground of the image, Ithaca Chasma can be seen running roughly north-south for more than 1,000 kilometers (620 miles) on Tethys. See PIA07734 for a closer view. Titan's detached, high-altitude haze layer and north polar hood are also visible here. See PIA09739 and PIA08137 to learn more. This view looks toward the Saturn-facing sides of Titan (5150 kilometers, 3200 miles across) and Tethys (1062 kilometers, 660 miles across). The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Oct. 18, 2010. The view was obtained at a distance of approximately 2.5 million kilometers (1.6 million miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 55 degrees. The view was obtained at a distance of approximately 1.5 million kilometers (932,000 miles) 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 9 kilometers (6 miles) per pixel on Tethys.
