Bright Moons
Date: 25 Apr 2011

The Cassini spacecraft observes three of Saturn's moons set against the darkened night side of the planet.

Saturn is present on the left of this image, but is too dark to see. Rhea (1,528 km, or 949 miles across) is closest to Cassini here and appears largest at the center of the image. Enceladus (504 km, or 313 miles across) is to the right of Rhea. Dione (1,123 km, or 698 miles across) is to the left of Rhea, partly obscured by Saturn.

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

The image was taken in visible red light with the Cassini spacecraft narrow-angle camera on 25 April 2011. The view was obtained at a distance of approximately 2.2 million km (1.4 million miles) from Rhea and at a sun-Rhea-spacecraft, or phase, angle of 67 degrees. Image scale is 13 km (8 miles) per pixel on Rhea. The view was obtained at a distance of approximately 3 million km (1.9 million miles) from Enceladus and at a phase angle of 67 degrees. Image scale is 18 km (11 miles) per pixel on Enceladus. The view was obtained at a distance of approximately 3.1 million km (1.9 million miles) from Dione and at a phase angle of 67 degrees. Image scale is 19 km (12 miles) per pixel on Dione.
