The problem with binaries/trinaries has always been that there's no way to
calculate up front what a stable arrangement would be (that I'm aware
of). I can stick three stars there in the display, but it's unlikely it'd
be a stable orbit. Planets of those stars have the same problem. So I may
try it, but realize that its unlikely they'll be correct/stable
arrangements. It'll just be a static display to show relative distance.

Similar problem with the temperature. Not every system is capable of
having a planet of a certain temperature. The temperature of a planet is
derived from a number of pieces of info, and the process is one way - you
cant reverse engineer it.

For planets, its best to just manually add them in and change their
temperatures. Or perhaps make a script that can place a planet at an
estimated distance. There's a TempAt() method of the Body class that will
let you get the 'equilibrium' temperature at a certain distance from a star.
