You can watch the stars move with this animation, I have been trying for some time to figure out how to create similar plots but so far no luck with Celestia.... maybe the more adventurous script writers want to tackle it. It would be great to be able to zoom back 50,000 years and look at the big dipper as it was.

I like the idea.
Too bad Celestia has this 16k ly barrier. All our stars would reach the barrier, and cease to exist. (quite an anomalous observation from Earth, seeing stars disappear one after the other as the stars go off in their own paths).

Star motion: excellent idea. I don't think it's feasable though.

Suppose to have three corps: Earth, Moon, Sun.
First you can solve the problem for the Earth and the Moon with the ipothesis of earth blocked. Then you search the center of mass of the system Earth-Moon and solved the problem for the Sun and the center of mass of Earth-Moon (with mass=mass of earth+mass of moon).
And so for the others corps of universe. Is it possible to run it on celestia?
