Ices and Shadows – Cassini Views Saturn’s Moon Tethys

NASA’s Cassini Spacecraft views Saturn’s moon Tethys.

Saturn’s moon Tethys appears to boyant between dual sets of rings in this perspective from NASA’s Cassini spacecraft, though it’s only a pretence of geometry. The rings, that are seen scarcely edge-on, are a dim bands above Tethys, while their curving shadows paint a world during a bottom of a image.

Tethys (660 miles or 1,062 kilometers across) has a aspect stoical mostly of H2O ice, most like Saturn’s rings. Water ice dominates a icy surfaces in a a distant reaches of a solar system, though ammonia and methane ices also can be found.

The picture was taken in manifest light with a Cassini booster wide-angle camera on Nov 23, 2015. North on Tethys is up. The perspective was performed during a stretch of approximately 40,000 miles (65,000 kilometers) from Tethys. Image scale is 2.4 miles (4 kilometers) per pixel.
