Adding custom object to Stellarium (no official orbits from e.g. MPC)

[Mikołaj K.]

Hello all,

Does anyone of you have idea of how to add a spacecraft (like STEREO-A) orbit to Stellarium files that allows to then change my position in Location -> Planet tab to this object?

I'm asking the same about custom comets, for example a preliminary orbit that hasn't got an official MPEC or orbit.

Kepler-like elements for  heliocentrical orbits with are stored in ssystem_minor.ini. See User Guide, Appendix.
