Janus, from VERY close!

Caption NASA:"The Cassini spacecraft provides this dramatic portrait of Janus against the cloud-streaked backdrop of Saturn.
Like many small bodies in the Solar System, Janus (about 181 Km, such as approx. 113 miles across) is potato-shaped with many craters, and the moon has a surface that looks as though it has been smoothed by some process.
Like Pandora and Telesto, Janus may be covered with a mantle of fine dust-sized, icy material.

The image was taken using a spectral filter sensitive to wavelengths of infrared light centered at 930 nanometers.

This view was acquired with the Cassini spacecraft narrow-angle camera on Sept. 25, 2006 at a distance of approx. 145.000 Km (such as about 90.000 miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 62°. North on Saturn is up. Image scale is roughly 871 mt (about 2.858 feet) per pixel".
