:| "_ THE RINGS OF SATURN _" /|:
viewed askew as a cylinder can be seen
{currently no link available put link here}
to violate the orbatal dictates about
how things that are far orbit slowly
and things near the primary orbit
quickley, as the rate of rotation
NEAR AND FAR appear to me at least,
to have a uniform period of rotation.
call it the Saturn ring rate (Srr).?
My guess? the disk (cylinder) rotates
together as a singular solid due to
electro static charges. and that makes it appear solid

Hi HUb'. I looked all this up a while back for another thread, so maybe I can answer it.

The rings of Saturn appear solid, but that isn't really the case. It's not a single rotating body. It's actually made up of innumerable small particles each in separate orbits. These orbits are "herded" into distinct regions by shepherding moons. In other words, the moons keep the particles from drifting out of the planar regions, but they still follow normal orbital mechanics otherwise.

Here's the Nine Planets link to Saturn's rings:
http://www.seds.org/nineplanets/nineplanets/saturn.html

I found it interesting how all the small moons work together to create structure. The biggest example seems to be how Mimas is responsible for the Cassini gap. See the BA's own page about it:

http://www.badastronomy.com/bitesize/saturnrings.html

Electrostatic charges may be involved in creating some of the spoke-like structures seen, as explained in this FAQ:

http://www.jpl.nasa.gov/saturn/faq.html#spokes

I think Saturn's rings are really more analogous to a spiral galaxy, where all the individual star orbits combine to create a seemingly solid disk and outside forces such as gravity perturbations, compression waves, and the like create the structure we can see.

now listen if you will? what I see in the
anamitation from growler are rings that
rotate as a solid {inside & outside orbit}
{have the same angular period}[whatever?]
and the spokes arn't magnetic shadows of
reflected light? maybe I just have it wrong
again already {Casinni should give the rates}

I mean the mean speed of the bigger particles

so I will wind up nit picking Ca.sin.i

So? this time the trail lead off to bitesize
and harmonic theory of 1/5's and 1/3rds etc
orbatal dynamics and periods, for myself
i'll skip to discCORD and K_us etc.
and later attempt to catch up on Casinni
Which with me watching will no doubt
turn the wrong way? oh well later

I think the solid seeming rotation is just an optical illusion because we can't see the actual individual rings or particles orbiting seperately. I think doppler shift readings would show actual rotation rates, and I'm sure we'd be inundated with news and cranks if it was discovered they were all rotating at the same rate. /phpBB/images/smiles/icon_smile.gif The spokes may be rotating at a constant rate though, as they seem to be dust particles dragged along by Saturn's magnetic field outside of the ring plane. That might be contributing to the illusion.

Boy, I hope not! it's taking Cassini long enough to get out there as it is. It would be real depressing to see it bung up in the home stretch. I can't wait to see what it turns up either. I have a feeling we're in for a flood of images and info better than anything we've gotten anywhere except from the Moon landings.

Ohayo to you too, tomodachi. Though it's actually night here now. /phpBB/images/smiles/icon_smile.gif Actually I'm really from Texas. I'm just enjoying experiencing another culture right now (as if my name wasn't a giveaway in that regard). /phpBB/images/smiles/icon_biggrin.gif

HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
Well I cant rule out the magnetic field stuff
maybe the Feild turns the dark sides up
or else stand the bits on edge to make
up the "spokes" tail? {hmm?}

H why oh why when the put rover on the moon? did they not make them remote controled, so after AstroNut left they could do X_plor
Hmm?

Thank you very much for the compliment. But I don't think it really was much. I was just rehashing the same stuff I looked up for the last thread.

I must admit, ring systems, especially Saturn's, hold a fascination for me. Aren't they one of the most beautiful and incredible phenomenon out there? It's only through looking it all up here that I finally understood just how they work in reality.

HUb', I hope you finally get to understand how these things work. Like you, I'm waiting with baited breath for 2004 to arrive. I think Saturn has a few surprises in store for us when Casinni get's there, and we may find we were all wrong.
