PIA01373: Saturn's Satellite Dione

Saturn’s Satellite Dione


This picture of Saturn's satellite Dione was taken by NASA's Voyager 1 on Nov. 9, 1980 from a distance of 4.2 million kilometers (2.6 million miles). Light and dark patches are visible on the moon's surface, reminiscent of features seen on Jupiter's satellite Ganymede during Voyagers's Jupiter encounter last year. The bright spots may be rays emanating from impact craters on Dione's surface. Dione is about 1,110 kilometers in diameter, about one-third the size of Earth's Moon. The smallest detail seen in this image is about 78 kilometers (48 miles) across.

The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
