Is there any working directory of stars of the Milky Way with [x,y,z, t] coordinates ? a galaxy class coordinate system ?

  I've seen databases of nearby stars, with just the 3D coords. Biggest I think had 100,000 stars. I don't think we have detailed data for the 100 million stars of the entire Milky Way.

    There’s at least 100 billion (not million). Maybe as many as 800 billion. We can’t see most of them.

      Oops, of course you're right.

  If you're looking for a dataset, the GAIA project public data releases[1] are probably the best you'll find. [1] https://www.cosmos.esa.int/web/gaia/dr2 https://www.cosmos.esa.int/web/gaia/dr2

  I'm assuming something like the Gaia dataset was used to create this representation of stars near us? https://stars.chromeexperiments.com/ https://stars.chromeexperiments.com/
