B Centauri
The Bayer designation A Bayer designation is a stellar designation in which a specific star is identified by a Greek or Latin letter followed by the genitive form of its parent constellation's Latin name. The original list of Bayer designations contained 1,564 stars. T ...s b Centauri and B Centauri are distinct. Due to technical limitations, both designations link here.

Bayer Designation
A Bayer designation is a stellar designation in which a specific star is identified by a Greek or Latin letter followed by the genitive form of its parent constellation's Latin name. The original list of Bayer designations contained 1,564 stars. The brighter stars were assigned their first systematic names by the German astronomer Johann Bayer in 1603, in his star atlas '' Uranometria''. Bayer catalogued only a few stars too far south to be seen from Germany, but later astronomers (including Nicolas-Louis de Lacaille and Benjamin Apthorp Gould) supplemented Bayer's catalog with entries for southern constellations. Scheme Bayer assigned a lowercase Greek letter (alpha (α), beta (β), gamma (γ), etc.) or a Latin letter (A, b, c, etc.) to each star he catalogued, combined with the Latin name of the star's parent constellation in genitive (possessive) form. The constellation name is frequently abbreviated to a standard three-letter form. For example, Aldebaran in the constellation ...

Naming Conventions (technical Restrictions)
A naming convention is a convention (generally agreed scheme) for naming things. Conventions differ in their intents, which may include to: * Allow useful information to be deduced from the names based on regularities. For instance, in Manhattan, streets are consecutively numbered; with east–west streets called "Streets" and north–south streets called "Avenues". * Show relationships, and in most personal naming conventions * Ensure that each name is unique for same scope Use cases Well-chosen naming conventions aid the casual user in navigating and searching larger structures. Several areas where naming conventions are commonly used include: * In astronomy, planetary nomenclature * In classics, Roman naming conventions * In computer programming, identifier naming conventions * In computer networking, naming scheme * In humans, naming offspring * In industry, product naming conventions * In the sciences, systematic names for a variety of things Examples Examples of ...

HD 129116
HD 129116 is a binary star in the northeastern part of Centaurus, east of Menkent. It is also known by its Bayer designation of b Centauri, while ''HD 129116'' is the star's identifier in the '' Henry Draper catalogue''. This object has a blue-white hue and is faintly visible to the naked eye with an apparent visual magnitude of +4.01. It is located at a distance of approximately 325 light years (100 parsecs) from the Sun based on parallax, and has an absolute magnitude of −1.07. The primary star is a hot type-B star with a spectral type of B3V and a mass of 5 to 6 times the solar mass. The secondary star is a close companion separated by approximately 1 AU, with up to 4.4 times the solar mass. In 2021, a massive exoplanet was discovered by direct imaging orbiting the pair of stars (a circumbinary planet) at a distance of about 560 AU. Star system This is a young stellar system, belonging to the Upper Centaurus–Lupus subgroup of the Scorpius� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HD 102964
HD 102964, also known as B Centauri, is a single star in the southern constellation of Centaurus. It has the identifier ''HD 102964'' in the '' Henry Draper catalogue''; ''B Centauri'' is the star's Bayer designation. This object has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude of +4.47. The star is located at a distance of approximately 440 light years from the Sun based on parallax, and has an absolute magnitude of −1.14. This object is an aging giant star with a stellar classification of K3III, indicating the star has exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. At present it has 39 times the girth of the Sun. It is radiating 480 times the luminosity of the Sun from its enlarged photosphere at an effective temperature The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of el ...

β Centauri
Beta Centauri is a triple star system in the southern constellation of Centaurus. It is officially called Hadar (). The Bayer designation of Beta Centauri is Latinised from β Centauri, and abbreviated Beta Cen or β Cen. The system's combined apparent visual magnitude of 0.61 makes it the second-brightest object in Centaurus and one of the brightest stars in the night sky. According to parallax measurements from the astrometric Hipparcos satellite, the distance to this system is about . Nomenclature ''β Centauri'' (Latinised to ''Beta Centauri'') is the star system's Bayer designation. It bore the traditional names ''Hadar'' and ''Agena''. ''Hadar'' comes from the Arabic Øضار (the root's meaning is "to be present" or "on the ground" or "settled, civilized area"), while the name ''Agena'' is thought to be derived from the Latin ''genua'', meaning "knees", from the star's position on the left knee of the centaur depicted in the constellation Centaurus.
