had a margin of error larger than the parallax itself and so gave little information about its distance. The distance of 6,000 pc is based on assumptions about the properties of LBVs, models of interstellar extinction, and kinematical measurements. The Gaia DR1 parallax, derived from the combination of the first year of Gaia measurements with Tycho astrometry, is . The Gaia team recommend that a further 0.3 mas systematic error is allowed for (i.e. added to the formal margin of error). A 2017 study argues that the 0.3 mas systematic margin of error can be ignored and that the implied distance to AG Carinae is . In Gaia Data Release 2, the parallax is , suggesting a distance around . A 2019 observation yields a most likely distance of . Gaia Early Data Release 3 gives a parallax of , although with a non-trivial level of excess astrometric noise where there was none in Gaia DR2.
