I think you can build solar systems but I never figured out how

It is a simulator only as accurate as what we model on it. Things such as dark matter and energy are not considered, as well as the cumulative effects of other galaxies. Over a short period of time, it is accurate. Allow it to run a fair amount of time, it becomes inaccurate.

You can't build a solar system from scratch, but you can edit systems by clicking planet editor.

Not really the right place to ask, but I help run a portable planetarium thing, and would like to use it. Any easy way output the screen to one window, but have the hud/control options in a second?
