Enceladus

Caption NASA:"The Cassini spacecraft acquired this view 15 hours before closest approach to Enceladus as the Spacecraft dove toward its thrilling March 2008 encounter with the ice-particle-spewing moon. The cratered terrain of the North is seen at top, and is even dimly visible on the moon's night side, which is lit by reflected sunlight coming from Saturn.
North on Enceladus (505 Km, or approx. 314 miles across) is up and rotated 22° to the left. The North Pole is tilted slightly toward Cassini.

The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on March 12, 2008. The view was acquired at a distance of approx. 612.000 Km (about 380.000 miles) from Enceladus and at a Sun-Enceladus-Spacecraft, or Phase, angle of 114°.
Image scale is roughly 4 Km (about 2 miles) per pixel".
