The Cassini spacecraft photographed the moon Tethys (right) and in particular the crater Odysseus, and at the same time the giant moon Titan (left) appeared in the background.
Titan, which is 5,150 km in diameter is covered in a thick and foggy atmosphere, and therefore many stray rocks burn up in the atmosphere and do not reach the bottom, and therefore do not create impact craters on the lunar surface. On the other hand, the crater-scarred Tethys (1,071 kilometers in diameter) is not protected, although even a thick blanket of atmosphere would not help against the bone that created Odysseus Crater.
The eastern lip of Tethys is overexposed in this image. The image was taken in visible light using Cassini's narrow-angle camera on January 6, 2006 from a distance of about 4 million kilometers from Titan and 2.7 million kilometers from Tethys. The scale is 25 kilometers per pixel on Titan and 16 kilometers per pixel on Tethys.
