A catalogue of 118 218 stars down to 12th magnitude observed by the Hipparcos satellite between 1989 August and 1993 March. The catalogue gives positions, parallaxes, proper motions, magnitudes, and colour indexes of these stars for the epoch 1991.25, with supplementary volumes giving additional information on double and variable stars. In 2007 a new version of the catalogue was published, called Hipparcos, the New Reduction, which corrected for slight irregularities in the satellite’s motion resulting in positional accuracies up to four times better than the original catalogue.
