Respected Sir / Madam,

Is there any repository of astronomical data like velocity of stars, their distances, Hubble constant at that time and their mass?

Regards,

Hello, thank you for reaching out.

For stars, their velocities, parallaxes (from which one can compute distances), etc., the Gaia survey is certainly the best resource.

Data Lab hosts the Gaia Data Releases 1, 2, and the "Early Data Release 3": You can browse the table schemas here: https://datalab.noirlab.edu/query.php

More information about the Gaia surveys can be found, e.g., here: https://sci.esa.int/web/gaia/-/28820-summary

Best regards,

Robert
