I've been playing around with Celestia, but I am unsure exactly how to script new bits into the Universe. How do you build you own Solar System? That's what I really want to do. The user guide that I downloaded only features commands that change the luminosity of stars that already exist and so on- so any help would be great.
Forgive me if I'm pretty stupid- I'm really bad at working things like this out. Can anyone explain simply how to do it from scratch? Or link me to a page or something?
Thank you for your time in advance.
