Several companies claim to sell the right to name a star, complete with certificates and coordinates. While these offers can be appealing, they carry no scientific weight.
The International Astronomical Union (IAU) is the sole authority that assigns official names and designations to stars. The IAU does not sell star names, nor does it grant licenses to private entities.
Most stars receive numeric identifiers rather than conventional names. Only a handful of historically significant stars—such as Sirius, the brightest point in the night sky—retain traditional names recognized by the scientific community.
The IAU also names newly discovered exoplanets, galaxies, and other astronomical objects. Commercial registries that offer “star” or “planet” names therefore lack any official status in the eyes of professional astronomers.
Although a registry’s name does not appear on scientific catalogs, the novelty can spark interest in astronomy. Some people enjoy the symbolic gesture of “naming” a star as a personal or commemorative gift.
Ultimately, if you’re looking for an officially recognized name, your best bet is to consult the IAU’s catalog. For those seeking a unique memento, a reputable registry can provide a certificate and coordinates—just be clear that it’s a symbolic gesture, not a scientific designation.
