This compendium summarises the astronomical data for all stars brighter than magnitude 8.0. For every object listed, it includes designations from the HD (Henry Draper) and SAO (Smithsonian Astrophysical Observatory) star catalogues; the star name and constellation; the common name; the position for the equinox and epoch 2000.0; the star's proper motion; its visual magnitude and colour index; the absolute magnitude; the spectral type; the radial velocity; the infrared distance; and, where appropriate, additional information on multiplicity, variability and cluster membership. There is an index of Flamsteed and Bayer designations as well. The information given in this catalogue is derived from the SIMBAD (Set of Identifications, Measurements and Bibliographical references of Astronomical Data) database held at the Strasbourg Observatory. This is the definitive reference set used in professional astronomy. Serious observers of stars and star systems will appreciate the new edition of this established reference work.
