Many star names are, in origin, descriptive of the part in the constellation they are found in; thus Phecda, a corruption of Arabic فخذ الدب ( fakhdh ad-dubb, 'thigh of the bear'). Only a handful of the brightest stars have individual proper names not depending on their asterism; so Sirius ('the scorcher'), Antares ('rival of Ares ', i.e ...
BPM 37093 — a diamond star. Cygnus X-1 — X-ray source. EBLM J0555-57Ab — is one of the smallest stars ever discovered. GY Andromedae — chemically peculiar variable star. MACS J1149 Lensed Star 1 (or Icarus) — second most distant star, 9 billion light years away.
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 ...
In practice, names are only universally used for the very brightest stars ( Sirius, Arcturus, Vega, etc.) and for a small number of slightly less bright but "interesting" stars ( Algol, Polaris, Mira, etc.).

All stars but one can be associated with an IAU (International Astronomical Union) constellation. IAU constellations are areas of the sky. Although there are only 88 IAU constellations, the sky is actually divided into 89 irregularly shaped boxes as the constellation Serpens is split into two separate sections, Serpens Caput (the snake's head) to the west and Serpens Cauda (the snake's tail ...

Astronomical naming conventions. In ancient times, only the Sun and Moon, a few stars, and the most easily visible planets had names. Over the last few hundred years, the number of identified astronomical objects has risen from hundreds to over a billion, and more are discovered every year. Astronomers need to be able to assign systematic ...
