Multiple
impact craters are seen on the ancient surface of Saturn's moon
Rhea in this picture taken by Voyager 1 on Nov. 12, 1980 at a range
of 73,000 km.
The craters closely resemble those on Mercury and Earth's Moon. Many of the craters have central peaks formed by rebound of the floor during the explosive formation of the crater. The craters are old and degraded by later impacts. Crater diameters seen are as large as approximately 75 km. Many have sharp rims and appear relatively fresh while others are very shallow and have subdued rims, indicative of their antiquity. |
