How to name the celestial bodies in the universe
Who is responsible for naming the huge number of celestial bodies in the universe? What's up with the weird alphanumeric names given to these objects? The International Astronomical Union (IAU), founded in 1919, is an international association of professional astronomers that assigns names and designations to celestial objects and their surface features. Its mission is to promote and preserve all aspects of astronomy. One needs to understand the difference between the terms "name" and "name". Names refer to terms we use in everyday life, while designations are only alphanumeric and are used almost exclusively in official catalogs and professional astronomy. When a new star is discovered, the standard practice is to use an alphanumeric designation. These names are practical because the stellar catalog contains billions of objects. The name consists of two parts: an acronym and a sequence value. An acronym is a code that specifies a source directory or collection. The sequence value is an string , usually composed of alphanumeric characters, used to uniquely identify the source in the directory.
blackhole does not follow any specific convention. Supermassive black holes are numbered according to the galaxy in which their core is located. For example, NGC 4261, NGC 4151 and M31, their names come from the new general catalog and Messier object list. Other stellar black holes are classified by their constellation and order of discovery. But black holes are mostly designated by their location in the sky, prefixed by the instrument or survey that discovered them. For example, RX J1131−1231 was observed by the Chandra X-ray Observatory .
Tens of thousands or more celestial bodies were originally named this way. The sky is filled with dazzling stars, which one is your most familiar and favorite?
