Thumbling Hyperion

Caption NASA originale:"As it loops around Saturn, Cassini periodically gets a good view of Saturn's moon Hyperion. Hyperion chaotically tumbles around in its orbit and is perhaps the largest irregularly-shaped moon in the Solar System. New details about this oddball worldlet will certainly come to light in September, 2005, when Cassini is slated to approach Hyperion at a distance of 990 Km. The images were taken in visible light with the Cassini spacecraft narrow-angle camera in October 2004 and February 2005, at distances ranging from 1,3 to 1,6 MKM (such as from approx. 808.000 to 994.000 MMs) from Hyperion and at phase angles ranging from 42 to 66°. Resolution in the original images was 8 to 10 Km (approx. 5 to 6 miles) per pixel.
The images have been contrast-enhanced and magnified by a factor of two to aid visibility".
