Polydeuces (extra detail mgnf)

This magnified view shows tiny Polydeuces, a moon that was discovered by the Cassini spacecraft and is a mere 3 Km (a little less than 2 miles) across. Along with much larger Helene (32 Km, or 20 miles across), Polydeuces orbits Saturn at the same distance as large, icy Dione (which is 1.126 Km, or 700 miles across).
Because this body was only recently discovered and is so small, scientists presently know precious little about it. Further observations by Cassini may yield additional insights about its nature and composition.

The image was taken with the Cassini spacecraft narrow-angle camera on May 22, 2006 at a distance of approx. 73.000 Km (about 45.000 miles) from Polydeuces and at a phase angle of 41°. The image was obtained using a spectral filter sensitive to wavelengths of infrared light centered at 752 nanometers. Scale in the original image was about 434 mt (appx. 1423 feet) per pixel. The image has been magnified by a factor of 4 and contrast-enhanced to aid visibility.
