Motivation
editThis proposal is inspired by Wikidata:Property_proposal/SIMBAD_catalog_properties_(used_more_than_1_million_times) by User:Mahir256. In 2024 (and probably for a few years to come), Gaia DR3 ID is considered the most reliable star identifier and provides access to the most accurate astrometric information.
