Don’t Forget Telesto

Saturn's moon Dione dwarfs the moon Telesto in this Cassini spacecraft image.

Dione (1123 kilometers, 698 miles across) is the fourth largest of Saturn's moons, and it dominates this view. Tiny Telesto (25 kilometers, or 16 miles across) can be seen below and to the left of Dione.

This view looks toward the anti-Saturn side of Dione. North on Dione is up. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 4, 2010. The view was acquired at a distance of approximately 477,000 kilometers (296,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 72 degrees. Scale on Dione is 3 kilometers (2 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
