Celestia Forums

I always prefered Celestia because it has always proved accurate in the past; however, I was reading about Barnard's star, and compared it to Celestia. Positions were so far off I can not recognize the same pattern of stars surround it.

Also, This star is apparently traveling 90 km/s, getting closer to us; Celestia fails to know/simulate this. The directions and speed of many stars are known; does Celestia use this information?

I'm using windows version 1.6.1, is there a more up-to-date version that is more accurate?

Barnard's Star has a large proper motion. It moves an amount similar to the diameter of the Moon every century or something like that. Celestia also does not include many stars beyond the Hipparcos catalogue, which may account for the discrepancy you're facing.

No, Celestia does not model proper motions.
