  • Planetary rings are the only nearby astrophysical disks, and the only disks that have been investigated by spacecraft (especially the Cassini spacecraft orbiting Saturn). Although there are significant differences between rings and other disks, chiefly the large planet/ring mass ratio that greatly enhances the flatness of rings (aspect ratios as small as 10−7), understanding of disks in general can be enhanced by understanding the dynamical processes observed at close-range and in real-time in… CONTINUE READING
