Enceladus and Dione

 

Two icy moons meet on the sky in a "mutual event" recorded by the Cassini

spacecraft.

 

 

The great brightness of Enceladus (505 kilometers, or 314 miles across) is

rather obvious in comparison to Dione (1,126 kilometers, or 700 miles

across) behind it. Enceladus is the most reflective object in the Solar

System, and is nearly pure white. Dione, in comparison, reflects about 70

percent of the light falling upon it.

 

 

The image was taken in visible light with the Cassini spacecraft

narrow-angle camera on July 24, 2007. The view was obtained at a distance

of approximately 1.9 million kilometers (1.2 million miles) from Enceladus

and 2.2 million kilometers (1.3 million miles) from Dione. Image scale is

11 kilometers (7 miles) per pixel on Enceladus and 13 kilometers (8 miles)

per pixel on Dione.

 

 

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.
