Lumpy Janus

July 2, 2013
The Cassini spacecraft catches a glimpse of Janus, an irregularly shaped moon. Lacking sufficient gravity to pull itself into a round shape, Janus has had its lumpy primordial shape only slightly modified by impacts since its formation.

This view looks toward the trailing hemisphere of Janus. North on Janus is up and rotated 44 degrees to the left. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 28, 2013.

The view was obtained at a distance of approximately 780,000 miles (1.3 million kilometers) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 77 degrees. Image scale is 5 miles (7 kilometers) per pixel.
