* No Official Registry: There is no single, globally recognized authority that officially names stars.
* Various Organizations: Different organizations, companies, and even individuals have their own star-naming schemes.
* Commercial Operations: Some companies offer the sale of "named stars" as a gift, but these names are not recognized by the scientific community.
* Historical Names: There are ancient and traditional names for a relatively small number of bright stars (e.g., Sirius, Vega, Polaris).
* Astronomical Catalogs: Astronomers use catalogs with designations (like Bayer, Flamsteed, or HD numbers) that are more scientific and consistent.
In summary: While there are many stars with informal names or names given by companies, these are not officially recognized. The vast majority of stars are known by their catalog numbers and designations.
