Do star's move in celestia?

[dusky]

Ok I am still getting used to celestia but on thing I have notice is that the star's (when looking from a galatic view like below) don't seem to move at all even when you set time to like 1 million years in the future. Are star's supposed to move according to there unique velocity in celestia? If so, how can I troubleshoot why they might not be moving. If not, is there an easy way to figure out where a star might be 500,000 years in the future. (I am curious to see if any exoplanets would actually get closer to use or not)

Proper motions of stars are not implemented in Celestia - their positions are fixed. Orbital motion of stars around a barycentre is possible, e.g. Alpha Centauri.

To put it another way, if you want to implement star motions yourself, Celestia does include facilities which would make it possible -- Stars could be defined with orbits relative to the galactic center, for example, or whatever barycenter is appropriate. EllipticalOrbit declarations require the SemiMajorAxis value to be in units of AU, which is somewhat awkward, but does work.
