According to INVESTIGATING THE RELATIVISTIC MOTION OF THE STARS NEAR THE SUPERMASSIVE BLACK
HOLE IN THE GALACTIC CENTER by M. Parsa, et al.,

the distance to Sag A* is 8.19 ± 0.11 ± 0.34 kpc, which is slightly less than the distance to the center of the Milky Way as used in Celestia v1.6.1.

Oh thanks, Selden.
I knew that this project was under way, but I had not seen the publication yet..
