Hereeeeeee we go again...

Basically, look in Celestia's Data folder and you'll find a solarsystem.scc file. .scc files provide the information for Celestia's solar systems. Open it in any text file. You'll see a bunch of text. Most of it's easy to work out -

texture - the texture for the planet;
radius - size;
Period - how long a planet takes to complete one orbit around its sun;
SemiMajorAxis - basically the distance from the planet to the sun;
Eccentricity - how non-circular the orbit is. 0 is a perfect circle, and as the number rises the more eccentric the orbit is (up to 1);
RotationPeriod - how long it takes for the planet to rotate (the day)
Albedo - Brightness and temperature - 0.1 is bright and cold, 1 is dark and hot

Hope you got all that. Once you've done creating a planet, save it as a .ssc file in the extras folder. Have fun...

Hi Alex,
I made a long reply to your other (duplicate) post,,,

there is one very small omission in it, in how to get to the planets dropdown,
but I expect you knew how to get there already ? I was just trying to cover all bases :)
