  Cassini catches a glimpse of Janus, an irregularly shaped moon. Lacking sufficient gravity to pull itself into a round shape, Janus (111 miles, 179 kilometers across) retains the lumpy shape it likely formed with.

See PIA10447 and PIA12714 for higher resolution views of Janus (111 miles, 179 kilometers across). See PIA08170 and PIA08348 to learn about how Janus periodically swaps orbits with Epimetheus.

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 777,000 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.

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.
