Epimetheus from 1,8 MKM
|
Caption NASA originale:"Small and asteroid-like in appearance, Epimetheus is seen here with Saturn's nearly edge-on rings in the distance. Epimetheus (that has been defined by NASA as a "rubble" moon - rubble----->macerie/detriti) has a mean density that is less than that of water, suggesting that it might be somewhat porous.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 12, 2005, at a distance of approx. 1,8 MKM (such as 1,1 MMs) from Saturn and at a phase angle of 90°. Resolution in the original image was 10 Km per pixel. The image has been contrast-enhanced and magnified by a factor of two to aid visibility".
