Mimas (396 kilometers, 246 miles across) orbits beyond the outer fringes of Saturn's main rings, perturbing the orbits of ring particles and creating gaps like the Huygens Gap within the Cassini Division (the wide, dark gap near lower left). The outer edge of the B ring (lower left corner) and the thin, outermost section of the A ring appear notably brighter than the bulk of the A ring, suggesting differences in ring particle density and/or composition. Small knots in the thin F ring are visible at lower right
This view is from Cassini's vantage point beneath the ringplane. The image was taken in visible green light with the narrow angle camera on November 18, 2004 from a distance of approximately 4.7 million kilometers (2.9 million miles) from Saturn.. The image scale is 27 kilometers (17 miles) per pixel. This image has been slightly contrast-enhanced to aid visibility.
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.
