Toward Melanthius

September 8, 2006

Cassini looks into the 245-kilometer (150-mile) wide crater Melanthius in this view of the southern terrain on Tethys. The crater possesses a prominent cluster of peaks in its center which are relics of its formation.

Notable here is a distinct boundary in crater abundance -- the cratering density is much higher in the farthest western terrain (left side of the image) than elsewhere.

North on Tethys (1,071 kilometers, or 665 miles across) is up and rotated 45 degrees to the left.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 23, 2006 at a distance of approximately 120,000 kilometers (75,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 29 degrees. Image scale is 715 meters (2,345 feet) per pixel.
