Well this is interesting...
NASA: Saturn's Moon Rhea Also May Have Rings
The Saturn system is turning out to be very interesting indeed... we already have Trojan satellites, horseshoe orbits and suchlike, and now possibly rings around a moon.
Rings around Rhea?

Hey, thanks very much for the link. Very interesting indeed.
What an amazing solar system we live in.

Or do we not have enough data.
We have far too little data. In addition, the ring system, if it exists, is not visible to the naked eye. As Cassini was departing Rhea, after the scientists had that ring idea, they turned the spacecraft at Rhea to search for rings with a 100 second shot. They found nothing. The ring, if it exists, is far, far too dark to be seen with the naked eye.
Current Setup:
Windows 7 64 bit. Celestia 1.6.0.
AMD Athlon Processor, 1.6 Ghz, 3 Gb RAM
ATI Radeon HD 3200 Graphics

Using the data I've seen so far, I simply edited the Rhea entry in the default solarsys.ssc file to this:
"Rhea" "Sol/Saturn"
{
Texture "rhea.*"
Radius 764
CustomOrbit "rhea"
EllipticalOrbit
{
Period 4.517500
SemiMajorAxis 527040
Eccentricity 0.0010
Inclination 0.35
MeanAnomaly 190
}
UniformRotation
{
Inclination 0.0
MeridianAngle 195.0
}
Albedo 0.7
Rings {
Inner 1614
Outer 2034
Texture "neptune-rings.png"
}
}
Later!

My version of Rhea
Well the rings are too bright, but i like it

Re: Rings around Rhea?
Spaceman, is your Rhea texture the old one made from Voyager data? ?

Re: Rings around Rhea?
We got a so much better 4k Rhea texture in the 1.6 distribution. Also those rings are FAR too bright (for obvious reasons). I guess they can hardly be seen in visual light.

I like the colors of the surface

My computer isn't fully upgrade yet, so i use for now 2K textures. I also use bright rings to see them, if they are too dim they will be invisible

It's very easy to (automatically) colorate Rhea with GIMP according to some nice colored template of your gusto! Also it's even easier to reduce the 4k Rhea map of the distribution to 2k.
