In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] 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 ...
z=3.395 This is a radio galaxy. At the time of discovery, quasar Q0051-279 at z=4.43, discovered in 1987, was the most remote object known. In 1989, quasar PC 1158+4635 was discovered at z=4.73, making it the most remote object known. This was the first galaxy discovered above redshift 3. It was also the first galaxy found above redshift 2.
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 .
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 ...

All are included on the current List of IAU-approved Star Names. [8] The star nearest to Earth is typically referred to simply as "the Sun" or its equivalent in the language being used (for instance, if two astronomers were speaking French, they would call it le Soleil). However, it is usually called by its Latin name, Sol, in science fiction.
