These names of stars that have either been approved by the International Astronomical Union or which have been in somewhat recent use. IAU approval comes mostly from its Working Group on Star Names, which has been publishing a "List of IAU-approved Star Names" since 2016. As of February 2025, the list included a total of 492 proper names of stars.
5th century Aryabhata writes a treatise on motion of planets, Sun and Moon and stars. Aryabhatta puts forward the theory of rotation of the Earth in its own axis and explained day and night was caused by the diurnal rotation of the Earth. He models a geocentric universe with the sun, moon, and planets following circular and eccentric orbits ...
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source
The Stelliferous Era, is defined as, "6 < n < 14". This is the current era, in which matter is arranged in the form of stars, galaxies, and galaxy clusters, and most energy is produced in stars. Stars will be the most dominant objects of the universe in this era. Massive stars use up their fuel very rapidly, in as little as a few million years.
The Book of Fixed Stars, a 10th-century synthesis of the comprehensive star catalogue in Ptolemy’s Almagest with local Arabic astronomical traditions on the constellations (notably the constellation system of the Anwā’). This page shows Orion (al-jabbar, "the giant"). The star Rigel in his foot derives its name from the Arabic rijl, "foot."
Bayer and Flamsteed covered only a few thousand stars between them. In theory, full-sky catalogues try to list every star in the sky. There are, however, billions of stars resolvable by 21st century telescopes, so this is an impossible goal; with this kind of catalog, an attempt is generally made to get every star brighter than a given magnitude.
A-type star In the Harvard spectral classification system, a class of main-sequence star having spectra dominated by Balmer absorption lines of hydrogen. Stars of spectral class A are typically blue-white or white in color, measure between 1.4 and 2.1 times the mass of the Sun, and have surface temperatures of 7,600–10,000 kelvin.
List of the largest known stars in the Magellanic Clouds Star name Solar radii (Sun = 1) Galaxy Method [a] Notes Theoretical limit of star size (Large Magellanic Cloud) ≳1,550 [11] L/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of stars. Assumes an effective temperature of 3,545 K.
