Help to make a (fairy complex) planetary system from scratch

Post #1by vpontin » 31.07.2019, 03:29


I want to make a fictional addon, a star system composed by a binary white dwarf (a pair orbiting a common barycenter), and one of the planets should be a quadruple planet (four earth-sized planets orbiting a barycenter) in the habitable zone.

I pretend to add another planets in future, but for now is just it.

Basic schematic of what i want:

I know how to edit existent star systems (stc and ssc) but i dont know how to start to make this from scratch.

Thanks in advance!

On the Celestia wikibooks, I believe there are sections for creating barycenters with stars and planets.

If you are using the windows based version, you may want to check in Celestia\extras\data\cc_Stars\cc_MultipleSystems\cc_Castor\

The original add-on was created by Phil Batchelor in 2008. You will find the code for the six star system of Castor (alf Gem).

This really helped me understand barycenters and how to code them in Celestia.

Have fun!

Planet barycenters are easier and look like this:

Code: Select all

ReferencePoint "Barycenter" "Sol"
   EllipticalOrbit {   
      Period            1.5000
      SemiMajorAxis     1.2500
      Eccentricity      0.0167
      Inclination       0.0001
      AscendingNode   348.739
      LongOfPericenter 102.947
           MeanLongitude   100.464

    # Make the orbit and label visible
    Visible true
    Clickable true
