Hi Silicon, welcome back. Permian Therapsid is right, I just checked and the satellite you added is referred to the main belt asteroid 2343 Siding Spring, discovered in 1979, not yet in SE catalog but it will be added now.
Comet Siding Spring you refer to it's a non-periodic comet discovered in 2013, C/2013 A1 Siding Spring. During that passage at perihelion went so close to Mars that several probes at the time in martian orbit could detect its dust.
I will add as soon as I can your contribution.
Hello
Mosfet, I did actually add this asteroid in one of my Main belt asteroids update that if do remember correctly,
SpaceEngineer did add to the catalog of the Solar System.
The addition however, I did post that in with the downloadable files included only on the
0.981 beta test thread. This is on page 11 of the tread. I did post there because I did change the code names assigned to some comets that had conflicting names with each other or with minor planets.
As you likely know many comets have been discovered by same observer. This is why there are comets with same names, and why comets with same names are usually referred as using names like
Shoemaker-Levy 9 for example to distinguish it from other "Shoemaker-Levy" comets when you do not want to use the full designation of the comet. I did use similar naming style in my update.
Minor planets however have unique names among themselves and this is why I did reserve the name "
Siding Spring" for the asteroid. And because my file used as a base the comet file from 0.981 I did post it only there. You can check it out if you want on the
0.981 beta test page 11
Mosfet.
