Making up a new solar system?

Asked by Joel Rees

How difficult would it be to use Solarium to simulate a made-up solar system in another galaxy?

The name of this program is Stellarium.

Read ssystem.ini to see how orbital elements for the minor planets are given. Just invent orbital elements for your planet system and delete all the major planets and their moons with coord_func=XXX_special.

However, the stars are cataloged in RA/DE2000 coordinates (with a bit of linear proper motion), so these are heliocentric and will not represent stars at your new location. Another problem is your new version of Earth. You could keep Earth in the planetary system as stable reference (maybe with different orbital data), or just as well delete it. I have not tried the consequences of deleting Earth (in real life we only have this one planet to keep and care for in a global effort with no excuses allowed!).

Thanks gzotti, that solved my question.

Oh, and sorry about the confusion about the name.

Hopefully I'll be able to put my simulation together with that. I'll leave a note when I do.
