Tycho-2 Catalogue

An astrometric and photometric catalogue of about 2.5 million of the brightest stars, derived from the star-mapper data of ESA's Hipparcos satellite. Named in honour of Tycho Brahe, it provides positions, proper motions, and two-colour photometry, and its 'TYC' identifiers are a standard reference for stars fainter than the main Hipparcos catalogue.
