PIX4625632: Saturn view of the surroundings of Dione - Illustration - Saturn from the vicinity of Dione - The planet Saturn seen from the surroundings of its satellite Dione. Dione, visible in the foreground, has a diameter of about 1100 km and is mainly composed of ice. In the background, another Saturn ice satellite is visible, Tethys. This is how Saturn might appear from near Dione, one of Saturn's inner icy satellites. Dione is about 700 miles in diameter and is believed to be composed primarily of water ice along with lesser amounts of silicate rocks. In this image, Dione is in the foreground orbiting about 197 thousand miles above Saturn's cloud tops. Further towards Saturn at a distance of 50 thousand miles from Dione is Tethys, another icy moon, slightly smaller than Dione. Tethys is silhouetted against the “” ring shine”” on Saturn's night side - - reflected sunlight on the cloud tops from Saturn's rings / Bridgeman Images
