Pumice-Hyperion (natural colors - elab. Lunexit)

Caption NASA:"Chaotically tumbling and seriously eroded by impacts, Hyperion is one of Saturn's more unusual satellites. Scientists believe the moon to be quite porous, with a great deal of its volume being empty space.
(...) Only part of the moon is visible in this image, the rest being hidden in shadow.

The image was taken with the Cassini spacecraft narrow-angle camera using a spectral filter sensitive to wavelengths of infrared light centered at 930 nanometers. The view was acquired on Feb. 15, 2007 from a distance of approx. 224.000 Km (such as about 139.000 miles) from Hyperion.
Image scale is roughly 1 Km (4.404 feet) per pixel".
