Tethys and Titan

Terrain on Saturn's moon Tethys, defined with craters, is shown in front of the hazy atmosphere of the larger moon Titan in this Cassini spacecraft image.

Titan is 5,150 kilometers, or 3,200 miles, across. Tethys is 1,062 kilometers, or 660 miles, across. This view looks toward the Saturn-facing sides of Titan and Tethys.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on October 17, 2009. The view was obtained at a distance of approximately 1.9 million kilometers (1.2 million miles) from Tethys and 2.9 million kilometers (1.8 million miles) from Titan. Image scale is 12 kilometers (7 miles) per pixel on Tethys and 17 kilometers (11 miles) per pixel on Titan.
