Hello all,

I wonder if there are software that would calculate the rate
of precession as you move through time, forward and backward.
For instance, in about 12 000 years, Vega will be the north star.
Are there software that would determine accurately the movements of all stars.

Thanks

Andre

Good question. I tried Redshift but the maximum date I could set it
to was 11000AD. And the constellations were the same, and Polaris was
in the same place.

I'm sure there are some programs because I've seen predictions of
where the stars will be and how the constellations will look. But
they might not be commercially available.
