Over the past few centuries, a small number of stars have been named after individual people. It is common in astronomy for objects to be given names, in accordance with accepted astronomical naming conventions. Most stars have not been given proper names, relying instead on alphanumeric designations in star catalogues. However, a few hundred had either long-standing traditional names (usually from the Arabic) or historic names from frequent usage. In addition, many stars have catalogue designations that contain the name of their compiler or discoverer. This includes Wolf, Ross, Bradley, Piazzi, Lacaille, Struve, Groombridge, Lalande, Krueger, Mayer, Weisse, Gould, Luyten and others. For example, Wolf 359 was discovered and catalogued by Max Wolf. Various private organizations claim to name stars in honor of people in exchange for a fee, but these names are used only within their own publications, and are not recognized by the scientific community. Names approved by the IAU The International Astronomical Union (IAU) is widely recognized by scientists and governments as the world authority for names of astronomical bodies, and lays down strict standards for this naming. In July 2014 the IAU launched NameExoWorlds, a process for giving proper names to exoplanets and their host stars, the outcome of which was announced in December 2015. As a result, the IAU approved two star names after individuals: Cervantes for the star Mu Arae honoring the writer Miguel de Cervantes Copernicus for the star 55 Cancri A honoring the astronomer Nicolaus Copernicus In 2016, the IAU organized a Working Group on Star Names (WGSN) which will catalog cultural and historical names for bright stars to help preserve astronomical world heritage, and maintain a catalog of IAU-approved unique proper names for stars. The WGSN's first bulletin of July 2016 set out its terms of reference and naming guidelines. All approved names are included on the current List of IAU-approved Star Names, last updated on 1 June 2018. The WGSN rules generally discouraged the naming of stars after people, but confirmed the names Cervantes and Copernicus as well as four others: Barnard's Star, the fourth-closest star to the solar system, named after the American astronomer E. E. Barnard who discovered it has the highest known proper motion of any star. Cor Caroli (Latin for 'heart of Charles') for the star Alpha Canum Venaticorum, so named in honour of King Charles I of England by Sir Charles Scarborough, his physician. Sualocin
