CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Tiny by the Terminator

A pair of Saturn's moons appear insignificant compared to the immensity of the planet in this Cassini view along the terminator where day transitions to night.

Epimetheus (70 miles across, 113 kilometers) appears as a tiny black speck on the far left of the image, just below the thin line of the rings. The larger moon Enceladus (313 miles across, 504 kilometers) is also on the left, just a bit closer to the center of the image. The rings cast wide shadows on the southern hemisphere of the planet.

This view looks toward the northern, sunlit side of the rings from just above the ringplane.

The image was taken with the Cassini spacecraft wide-angle camera on Nov. 4, 2011 using a spectral filter sensitive to wavelengths of near-infrared light centered at 752 nanometers. The view was acquired at a distance of approximately 746,000 miles (1.2 million kilometers) from Saturn and roughly 621,000 miles (1 million kilometers) from Enceladus and Epimetheus. Image scale is about 47 miles (75 kilometers) per pixel on Saturn, 37 miles (60 kilometers) per pixel on Enceladus and 41 miles (66 kilometers) per pixel Epimetheus.

The Cassini Solstice Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. 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.
