PHOTO CAPTION (TOP) P-23945
S-2-40
Aug. 27, 1981
This composite shows seven of the very small satellites of Saturn
as photographed Aug. 25 by Voyager 2. These irregularly shaped
bodies have been highly cratered by the impact of cosmic debris.
The irregularity is probably due to fracturing by large impacts
and is sustained by the rigidity of the bodies. The lighting angles
and ranges here are different for each satellite; thus, true
relative sizes are not shown. These objects range from about 10
to several hundred kilometers across. Of note are the two F-ring
shepherding satellites, first seen by Voyager 1. The following
table corresponds to this composite photograph, with each satellite's
standard numerical designation and name and Voyager 2's range when
it took these frames:
