Object classifications for 1.59 billion sources and astrophysical parameters (T eff, logg,, A G, distance, etc.) from BP/RP spectra for 470 million objects, including MCMC samples for most sources with astrophysical parameters. Other astrophysical parameters from the BP/RP spectra include:.In Gaia Data Release 3 (Gaia DR3), the above set of data is complemented with new products released on 13 June 2022: G BP and G RP magnitudes for around 1.54 billion and 1.55 billion sources, respectively.G magnitudes for around 1.806 billion sources (with the known issue present in EDR3 corrected in Gaia DR3).In addition, two-parameters solutions - positions on the sky (α, δ) - for around 344 million additional sources.In the 6-parameter solution, the additional fitted quantity is the so-called pseudo-colour that had to be included for sources without high-quality colour information. The full astrometric solution has been done as 5-parameter solution for 585 million sources and as 6-parameter solution for 882 million sources.The astrometric solution is accompanied with some new quality indicators, like RUWE, and source image descriptors. The full astrometric solution - positions on the sky (α, δ), parallax, and proper motion - for around 1.46 billion (1.46 10 9) sources, with a limiting magnitude of about G ≈ 21 and a bright limit of about G ≈ 3.The set of data released as Gaia Early Data Release 3 (Gaia EDR3) on 3 December 2020 comprises: The full contents of Gaia DR3 is described below. The Gaia DR3 catalogue builds upon the Early Data Release 3 (released on 3 December 2020) and combines, for the same stretch of time and the same set of observations, these already-published data products with numerous new data products such as extended objects and non-single stars. The data is available through the Gaia Archive (and through the partner data centres). Gaia Data Release 3 (Gaia DR3) has been released on 13 June 2022.
