Tethys and Saturn



660-mile-wide Tethys orbits in front of Saturn and the rings in this image from Cassini, taken on March 8, 2011. The rings cast their shadows onto the Saturn’s southern equatorial cloudtops as the planet continues moving into its summer season.

The 155-mile-wide Melanthius Crater can be seen near Tethys’ south pole.

A smaller moon can also be seen near the rings, perhaps Enceladus? Not quite sure on that one, it’s a bit too small to make out. 🙂

This was originally a monochrome raw image…I colored it using the RGB composite results from this image upload to give Saturn its slight hue.
