Rhea, from about 255.000 Km
|
Saturn's moon Rhea is an alien ice world, but in this frame-filling view it is vaguely familiar. Here, Rhea's cratered surface looks in some ways similar to our own Moon, or the planet Mercury. But make no mistake - Rhea's icy exterior would quickly melt if this moon were brought as close to the Sun as Mercury.
Instead, Rhea preserves a record of impacts at its post in the Outer Solar System.
For exemple, the large impact crater at center left (near the terminator), called Izanagi, is just one of the numerous large impact basins on Rhea.
This view shows principally Rhea's Southern Polar Region, centered on 58° South and 265° West.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 1, 2005, at a distance of approx. 255.000 Km (such as about 158.000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 62°.
The image scale is 2 Km (about 1,2 miles) per pixel.
