The Second Ring-Moon System of Uranus: Discovery and Dynamics
Mark R. Showalter1* and Jack J. Lissauer2
Deep exposures of Uranus taken with the Hubble Space Telescope reveal two small moons and two faint rings. All of them orbit outside of Uranus's previously known (main) ring system but are interior to the large, classical moons. The outer new moon, U XXVI Mab, orbits at roughly twice the radius of the main rings and shares its orbit with a dust ring. The second moon, U XXVII Cupid, orbits just interior to the satellite Belinda. A second ring falls between the orbits of Portia and Rosalind, in a region with no known source bodies. Collectively, these constitute a densely packed, rapidly varying, and possibly unstable dynamical system.
TOPICS: Miscellaneous

I haven't lsot my sense of humor at all.....but as P.T.Barnum famously said,"Doing something funny 100 times doesn't make it 100 times as funny as doing it once."

Why else would someone post an astronomy article on a conservative political forum, but to inject some comic relief? I say, the anus jokes are free game!

I just wanted to see how long it would take for jokes about Uranus to show up.
Not long!

Not exactly like the 'ol "ring around the collar"...
"those dirty rings!"
