Re: Making a new system

Libration points you can easily sort out - Not if you're deriving your period from semimajor axis and mass, you can't - L1, L2 and L3 are decidedly non-Keplerian, since they move synchronously, but at very different distances from the central body. I thought all you needed to find the distances was...

Re: Making a new system

Celestia doesn't know anything about mass, so doesn't make that calculation. It's actually useful to be able to specify Radius and SemiMajorAxis independently, because then you can do all sorts of non-Keplerian tricks - setting up objects at libration points, or levitating them by light pressure, o...

Re: Making a new system

Thanks folks... I downloaded some of Rassilon's systems (Mira and Murphid and Eta Carinae - very pretty systems, but they're very bizarre orbitally!) and saw how he did his 'fake' companion stars... So there's no way at all in Celestia to put one star actually in orbit around another, and no way to ...

Re: Making a new system

Making a new system

First post here, hi all. :) After playing around flying through the solar system, I've decided to try to make my own planetary system in Celestia. I've been referring to http://www.lns.cornell.edu/~seb/celestia/addon-intro.html but the info there seems kinda basic for my purposes, so I have lots of ...
