The GAIA catalog has most of those (or data they can be computed from), probably not mass or age though. http://cdn.gea.esac.esa.int/Gaia/gdr3/gaia_source/

Thank you, @GregMiller. I just installed the Gaia Sky app and it is amazing!

Where to find data about as many stars as possible?

# Where to find data about as many stars as possible?

(Asked by: username_0 on 2023-07-07)

I need computer-readable data about as many stars as possible, with their:

* distance to the Earth (or Sun),
* their masses,

and if possible:

* coordinates,
* age,
* brightness
* distance to the center (Sagittarius-A) of the galaxy.

What is available? Which source of such data would be most recommended?
