Telesto

Caption originale:"The blob of light seen here is Saturn's moon Telesto, which shares its orbital path with much larger Tethys. Telesto is 24 Km across.
Although this view may hint at a flattened, potato-like shape for Telesto (a common shape for Saturn's smaller moons), no features on the moon's surface can be resolved here.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Aug. 1, 2005, at a distance of approximately 768.000 Km from Telesto and at a Sun-Telesto-spacecraft angle of 37°. Resolution in the original image was 5 Km per pixel. The image has been contrast-enhanced and magnified by a factor of 4 to aid visibility".
