Still Image 700x320:
  In a silent orbital ballet, crater-covered Rhea slips between Mimas and Enceladus. The dark sides of Enceladus (bottom) and Mimas (top) are dimly illuminated by reflected light from Saturn.

Rhea is 1,528 kilometers (949 miles) across, Mimas is 396 kilometers (246 miles) across and Enceladus is 504 kilometers (313 miles) across.

The movie was created using 59 clear filter images taken over a period of about 40 minutes. The images were acquired by the Cassini spacecraft narrow angle camera on Jan. 27, 2006 from a mean distance of approximately 3 million kilometers (1.9 million miles) from Rhea, 3.5 million kilometers (2.2 million miles) from Mimas and 3.7 million kilometers (2.3 million miles) from Enceladus. The image scale is approximately 18 kilometers (11 miles) per pixel on Rhea, 21 kilometers (13 miles) per pixel on Mimas and 22 kilometers (14 miles) per pixel on Enceladus.

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.
