S/ 2009 S 1

[volcanopele]

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.

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

Code: Select all

"S/2009 S 1" "Sol/Saturn"
{
   Class   "minormoon"
   Texture   "asteroid.jpg"
   Mesh   "roughsphere.cms"
   Radius      0.2
   Albedo   0.5
   EllipticalOrbit
   {
   Period               0.47208
   SemiMajorAxis   116930
   Eccentricity            0.0
   Inclination                    0.0
   MeanAnomaly        320      # Position in rings next to Cassini
   }
}
