Tethys Floating Past Saturn
This natural colour photograph shows Saturn’s moon Tethys going past the planet’s huge globe with the thin line of rings curving at the horizon. The craters Odysseus (top) and Melanthius (bottom) are also visible on Tethys surface. This image was captured at a distance of approximately 2.5 million kilometers (1.6 million miles) from Saturn by the Cassini spacecraft narrow-angle camera on Dec. 3, 2005.
