Pair to Compare Target Name:   Saturn Spacecraft:   Cassini Orbiter Instrument:   Imaging Science Subsystem - Narrow Angle Produced by:   NASA/JPL/Space Science Institute Copyright:  NASA Copyright Free Policy Cross Reference:   PIA06647 Date Taken:   19 March 2005 Related Documents Tethys Dione Cassini At Saturn Saturn Download Options Name Type Width x Height Size PIA06647.jpg JPEG 640 x 521 11K PIA06647.jpg JPEG 942 x 767 15K PIA06647.tif TIFF 942 x 767 706K Saturn's moon Dione occults part of Saturn's distant rings while Tethys hovers below. Dione is 1,118 kilometers (695 miles) across, while Tethys is 1,071 kilometers, 665 miles) across. This image offers excellent contrast with a previously released view (see PIA06629) that showed the bright, wispy markings on Dione's trailing hemisphere. The huge impact structure Odysseus (450 kilometers, or 280 miles across) is near the limb of Tethys. Compared with the battered surface of Tethys, Dione appears much smoother from this distance. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 19, 2005, at a distance of approximately 2.7 million kilometers (1.7 million miles) from Saturn. The image scale is approximately 15 kilometers (9 miles) per pixel.
