Tethys Walks the Line

September 24, 2007

The moon Tethys cruises past, in front of Saturn's edge-on rings. The rings cast threadlike shadows onto the northern hemisphere of the planet.

The large crater Odysseus can be seen on the eastern limb of Tethys (1,071 kilometers, or 665 miles across).

The image was taken with the Cassini spacecraft wide-angle camera on Aug. 7, 2007 using a spectral filter sensitive to wavelengths of visible light centered at 619 nanometers. The view was obtained at a distance of approximately 4.1 million kilometers (2.6 million miles) from Saturn. Image scale is 49 kilometers (30 miles) per pixel.
