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

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.
