Enceladus&C.-PIA08182.jpgMoons...56 visiteCaption NASA proginale:"Four of Saturn's many and varied moons crowd this single frame from Cassini.
All of the moons are illuminated by the Sun, which is out of the frame to the right. "Saturnshine", or reflected light from the planet (out of frame to the lower left), partly illuminates three of the moons, such as Tethys (1.071 Km, or 665 miles across, at upper right), Janus (181 Km, or 113 miles across, at lower left) and Epimetheus (116 Km, or 72 miles across, below and left of center).
Enceladus (505 Km, or 314 miles across) is much farther in the distance in this view, and shows merely a slim crescent below center.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 17, 2006, at a distance of approx. 3,7 MKM (such as about 2,3 MMs) from Saturn. The image scale is approx. 27 Km (about 17 miles) per pixel on Tethys, 21 Km (13 miles) per pixel on Enceladus, and 22 Km (14 miles) per pixel on Janus and Epimetheus".
