Saturn from the surface of Enceladus
This is how Saturn may appear from the icy surface of Enceladus, one of Saturn's eight major satellites. At a distance of 148 thousand miles, Saturn would subtend an angle of 29º in Enceladus' sky, about the same width as 58 Earth moon's lined up side-by-side.
While the surface of Enceladus is as reflective as new fallen snow, it would probably appear leaden about an hour before sunrise with a crescent Saturn as the only source of illumination. Like all of Saturn's major satellites, Enceladus always keeps the same side facing its host planet. From the perspective of a stationary observer on Enceladus, Saturn would always appear in the same position in the sky, cycling through its phases in about one-and-half Earth days.
This image also illustrates a phenomenon only recently discovered by NASA's Cassini probe: sunlight reflecting off of Saturn's rings casts a faint glow onto the cloud tops of Saturn's night side. The illumination is about the same as three of Earth's full moon combined.
