The Gaia catalogues are star catalogues created using the results obtained by Gaia space telescope. The catalogues are released in stages that will contain increasing amounts of information; the early releases also miss some stars, especially fainter stars located in dense star fields.

The Gaia catalogues are based on observations made by the Gaia space telescope. They are released in stages that contain increasing amounts of information; the early releases also miss some stars, especially fainter stars located in dense star fields. [34] Data from every data release can be accessed at the Gaia archive. [35]
Gaia is a space observatory of the European Space Agency (ESA) that was launched in 2013 and is planned to operate until March 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [5] [6] and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color.

The single parameter is used to create a link to an individual EDR3 entry in the VizieR database; this is optional but encouraged. The parameter should be the 19-digit Gaia EDR3 designation, listed in the catalogue as "Gaia EDR3 NNNNNNNNNNNNNNNNNNN". For example, to link to the database entry for WR 31a, which is Gaia EDR3 5338229115839425664:
During a 2021 survey [9] searching for binaries within data from Gaia EDR3, the star was found to be orbited by a 13th-magnitude [10] M-dwarf, designated HD 11343 B. It is about 70% as large as the Sun both in mass and radius, is slightly cooler than the primary red giant at 4,351 K (4,078 °C; 7,372 °F), and is situated at a separation of ...
Gaia EDR3 gives them parallaxes of 8.8125 ± 0.2471 mas and 8.5577 ± 0.0298 mas respectively, although they are flagged as potentially unreliable. [ 6 ] [ 7 ] These parallaxes correspond to a distance of around 380 ly , in contrast to the Hipparcos distance of 260 ± 20 ly for the two stars as a pair.
