List of brightest stars

This article is about apparent magnitude. For absolute magnitude, see List of most luminous stars.

This is a list of the brightest individual stars in determined by their average apparent magnitudes in the visible spectrum as seen from Earth. This is not the same as a list of the brightest stars as seen with the naked eye, as close binary or multiple star systems will appear as a single star with an apparent magnitude greater than their individual components, e.g. the binary system Rigel Kentaurus has an apparent magnitude of -0.27, but the brightest individual star is Alpha Centauri A with the apparent magnitude as listed here of -0.01. Hence Alpha Centauri is the third brightest star in the night sky, while its brightest component Alpha Centauri A is the fourth brightest individual star. Stellar brightness in this selected table is limited to brighter than +2.50 magnitude, mostly as the available number of observable stars increases almost exponentially as the magnitude increases.[1] To the naked eye on a clear dark night, in a location far from cities and lights, the total number of stars visible is around 9000 (9110 total objects in the Bright Star Catalogue of naked eye stars, including 9096 stars, ten novae or supernovae, and four clusters). Stars visible through optical aid increase this even further. Telescopically, the entire night's sky has been mapped, photographed and catalogued almost completely down to 11th magnitude, and recent star surveys are continuing to catalogue much fainter stars.

List[edit]

Below are listed the 93 brightest individual stars in order of their average apparent magnitudes.

For comparison, the non-stellar objects in our Solar System with maximum visible magnitudes below +2.50 are the Moon (−12.92), Venus (−4.89), Jupiter (−2.94), Mars (−2.91), Mercury (−2.45), and Saturn (−0.49).

An exact order of the visual brightness of stars is not perfectly defined for the following reasons:
