These names of stars that have either been approved by the International Astronomical Union or which have been in somewhat recent use. IAU approval comes mostly from its Working Group on Star Names, which has been publishing a "List of IAU-approved Star Names" since 2016. As of April 2022, the list included a total of 451 proper names of stars. [1]
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source
In astronomy, star names, in contrast to star designations, are proper names of stars that have emerged from usage in pre-modern astronomical traditions. Lists of these names appear in the following articles: List of Arabic star names; List of Chinese star names; List of proper names of stars: traditional proper names in modern usage around ...

The IAU's names for exoplanets – and on most occasions their host stars – are chosen by the Executive Committee Working Group (ECWG) on Public Naming of Planets and Planetary Satellites, a group working parallel with the Working Group on Star Names (WGSN). [1] Proper names of stars chosen by the ECWG are explicitly recognised by the WGSN. [1]
The Bright Star Catalogue, which is a star catalogue listing all stars of apparent magnitude 6.5 or brighter, or roughly every star visible to the naked eye from Earth, contains 9,096 stars. [1] The most voluminous modern catalogues list on the order of a billion stars, out of an estimated total of 200 to 400 billion in the Milky Way .
