![]() "Acrux" is a modern contraction of the Bayer designation, coined in the 19th century, but which entered into common use only by the mid-20th century. ![]() The traditional name of the β Scorpii system has been rendered Akrab and Elakrab, derived (like Acrab) from Arabic: العقرب al-ʿaqrab ('the scorpion'). The name was originally Arabic: آخر النهر ʾāẖir an-nahr ('river's end').Īpparently first applied to η Cassiopeiae in the Skalnate Pleso Atlas of the Heavens published in 1950, but is not known prior to that. In the "Historical names/comments" column, "IAU new 2015" and "IAU new 2019" denote that the name was approved by the IAU as a consequence of its 20 NameExoWorlds campaigns, respectively.Įnglish pronunciation Ĭzech Republic proposal a fictional substance in the novel Továrna na absolutno by Karel Čapek. Names marked with a "†" are no longer approved, while names marked with a "*" are names that were proposed or accepted since the last update to the list on 10 August 2018.įor such names relating to members of multiple-star systems, and where a component letter (from, e.g., the Washington Double Star Catalog) is not explicitly listed, the WGSN says that the name should be understood to be attributed to the visually brightest component. The WGSN decided to attribute proper names to individual stars rather than entire multiple-star systems. In the table below, unless indicated by a "†" or "*", the "modern proper name" is the name approved by the WGSN and entered in the List of IAU-approved Star Names or otherwise approved by the IAU. The approved names of 112 exoplanets and their host stars were published on 17 December 2019. In addition, in 2019 the IAU organised its IAU 100 NameExoWorlds campaign to name exoplanets and their host stars. All 336 names are included in the current List of IAU-approved Star Names, last updated on 10 August 2018. These were listed in a table of 102 stars included in the WGSN's second bulletin, dated November 2016. Further batches of names were approved on 21 August, 12 September, 5 October, and 6 November 2016. The WGSN's first bulletin, dated July 2016, included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee Working Group on the Public Naming of Planets and Planetary Satellites during the 2015 NameExoWorlds campaign and recognized by the WGSN. In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. Main article: IAU Working Group on Star Names "Avior" for Epsilon Carinae (1930), and a number of stars named after people (mostly in the 20th century). In addition to the limited number of traditional star names, there were some coined in modern times, e.g. ![]() The same holds for Chinese star names, where most stars are enumerated within their asterisms, with a handful of exceptions such as 織女 ('weaving girl') ( Vega). Only a handful of the brightest stars have individual proper names not depending on their asterism so Sirius ('the scorcher'), Antares ('rival of Ares', i.e., red-hued like Mars), Canopus (of uncertain origin), Alphard ('the solitary one'), Regulus ('kinglet') and arguably Aldebaran ('the follower' ) and Procyon ('preceding the dog' ). Many star names are, in origin, descriptive of the part of the constellation they are found in thus Phecda, a corruption of Arabic فخذ الدب ( fakhdh ad-dubb, 'thigh of the bear'). There are 88 constellations, which are only seen to the naked eye. Traditional astronomy tends to group stars into constellations or asterisms and give proper names to those, not to individual stars. Of the roughly 10,000 stars visible to the naked eye, only a few hundred have been given proper names in the history of astronomy.
