This is the Celestia definition I use for this recently announced satellite of Saturn, S/ 2009 S 1 that seems to work reasonably well given the available observation of it:
"2009 S1" "Sol/Saturn"
{
Class "minormoon"
Texture "asteroid.jpg"
Radius 0.15
EllipticalOrbit
{
Epoch 2455038.97976
Period 0.47249694420833
SemiMajorAxis 117000
Eccentricity 0.0000
Inclination 0.000 #
AscendingNode 0 #
ArgOfPericenter 0 # J2000.0
MeanAnomaly 145 #
}
UniformRotation
{
Inclination 0.0
MeridianAngle 296.8
}
Albedo 0.9
# single observation July 26, 2009 11:30:50
# position good-ish for that single observation, rest assumes Keplerian motion, which given interactions with neighboring ring
# particles maybe WAY off even a few months into the future
# orbit also assumes circular, non-inclined orbit
}
As noted, because this object is basically just a really big ring particle in Saturn's B ring, the position information for S/ 2009 S 1 is for the most part representative outside of the single observation of this object by Cassini. Object also assumed to have a circular, non-inclined orbit.

Re: S/ 2009 S 1
Old subject, but I also worked on a ssc-file for this moon. Here my result:
