Gaia catalogues
series of star catalogue releases from the Gaia mission
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. Data from every data release can be accessed at the Gaia archive.
Initial Gaia Source List
The Initial Gaia Source List (IGSL) is a star catalogue of 1.2 billion objects created in support of the Gaia mission. The mission should have delivered a catalogue based entirely on its own data. For the first catalogue, Gaia DR1, a way was needed to be able to assign the observations to an object and to compare them with the objects from other star catalogues. For this purpose, a separate catalog of objects from several other catalogues was compiled, which roughly represents the state of knowledge of astronomy at the beginning of the Gaia mission.
Attitude Star Catalog
The Attitude Star Catalog is a subset of the IGSL, required for the first approximation in the iterative evaluation of the Gaia data. A first version was created in 2013, a more refined version in April 2014. In total, the Attitude Star Catalog contains 8,173,331 entries with information on position, proper motion and magnitude.
The public source identifies “Gaia catalogues” as series of star catalogue releases from the Gaia mission. This brief keeps that definition visible, then builds a research path around Gaia, catalogues and series.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Gaia catalogues”, the useful work is to connect “series of star catalogue releases from the Gaia mission” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q138581113. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2013 and 2014.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.

Three-step research path
- Establish the record: confirm the title “Gaia catalogues”, its source revision and the description used here.
- Expand the search: follow Gaia catalogues primary sources, Gaia catalogues archive and Gaia research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
