Still Image 950x420:
  Three of Saturn's moons swim past in this movie sequence of images from Cassini. These sequences, called mutual events, are useful for refining the orbits of Saturn's moons.

The movie follows Epimetheus (113 kilometers, 70 miles across) as it passes in front of Titan (5,150 kilometers, 3,200 miles across) and then Dione (1,123 kilometers, 698 miles across).

The faint object that appears at left, below the ringplane, halfway through the movie is background star.

The movie was created using 24 clear filter images taken over a period of about 40 minutes. The images were acquired by the Cassini spacecraft narrow angle camera on Jan. 5, 2006 from a mean distance of approximately 3 million kilometers (1.9 million miles) from Epimetheus. The image scale is approximately 18 kilometers (11 miles) per pixel on Epimetheus, 25 kilometers (16 miles) per pixel on Titan and 20 kilometers (12 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 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.
