Analog to HarbingerDawn's thread Solar System Asteroids (open addon) I want to collect all your homemade comets, which are missing in the recent SpaceEngine.
I just started with the 67P/Churyumov–Gerasimenko.

Code
Comet    "Churyumov-Gerasimenko/67P (Churyumov-Gerasimenko)"
{
  ParentBody     "Sol"
  CometType      "P"
  AbsMagn         11.4
  SlopeParam      11
  Radius          2  
  Mass            1.673920e-12
  RotationPeriod  12.76137
   
  Orbit
  {
   Epoch            2456981.5
   Period           6.44
   SemiMajorAxis    3.462817302992186
   Eccentricity     0.6409739314162571
   Inclination      7.040200902346087
   AscendingNode    50.14210951437195
   ArgOfPericenter  12.78560606538363
   MeanAnomaly      319.3033467788339
  }
}

Cool, I had a go at adding Siding Spring, although it didn't coincide entirely with reality, but I thought it was close enough biggrin

Code

Comet "Siding Spring/C-2013 A1"
{
  ParentBody "Sol"
  CometType  "P"
  AbsMagn     1
  SlopeParam  4

  Radius         0.350
  Mass           1.681392236e-11 // 2.2e14 kg to Earth mass
  RotationPeriod 52.8

  Orbit
  {
   Epoch            2456960.5
   SemiMajorAxis    1883.920535902058  
   Eccentricity     1.00043
   Inclination      129.0273411347216  
   AscendingNode    300.9762794485837
   ArgOfPericenter  2.440972538934485  
   MeanAnomaly      -0.003186058483647941  
  }

  CometTail
  {
   MaxLength   0.5
   Bright  1.0

SpaceEngine already has it by default.

Would it be possible to create a bumpmap out of a (low-poly) asteroid 3D model? It sort of bugs me we can't just use 3D models for asteroids like in Celestia.




I will be inactive on this forum for the time being. Might come back eventually

Well, it was a good exercise in finding appropriate orbital information anyhow.
