Saturn's two largest moons meet on the sky in a rare embrace. Smog-enshrouded Titan (5,150 kilometers, 3,200 miles across) glows to the left of airless Rhea (1,528 kilometers, 949 miles across).
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 11, 2006 at a distance of approximately 3.6 million kilometers (2.2 million miles) from Rhea and 5.3 million kilometers (3.3 million miles) from Titan. The Sun-Rhea-spacecraft, or phase, angle is 157 degrees on Rhea. Image scale is 22 kilometers (13 miles) per pixel on Rhea and 32 kilometers (20 miles) per pixel on Titan.
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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
