Zeta Puppis (ζ Puppis, abbreviated Zeta Pup, ζ Pup), formally named Naos / n aʊ s /, [10] is the brightest star in the constellation of Puppis.. The spectral class of O4 means this is one of the hottest, and most luminous, stars visible to the naked eye.

The last stars in the list are familiar nearby stars put there for comparison, and not among the most luminous known. It may also interest the reader to know that the Sun is more luminous than approximately 95% of all known stars in the local neighbourhood (out to, say, a few hundred light years), due to enormous numbers of somewhat less ...
The closer star WR 25 may be more luminous than WR 102ka. [9] Another nearer star, Eta Carinae , which was the second-brightest star in the sky for a few years in the 19th century, appears to be slightly more luminous than WR 102ka, but is known to be a binary star system.
Prominent stars in the neighborhood of the Sun (center) This list of nearest bright stars is a table of stars found within 15 parsecs (48.9 light-years) of the nearest star, the Sun, that have an absolute magnitude of +8.5 or brighter, which is approximately comparable to a listing of stars more luminous than a red dwarf.
R71 has long been known as a blue supergiant and one of the brightest stars in the Magellanic Clouds.It was given a spectral type of B2.5 Iep. [7]By 1974, R71 had increased in brightness from about 11th magnitude to about magnitude 9.2, and examination of historical photographic plates showed that there had been similar changes in the past, with the brightness peaking around 1914 and 1939.

Alcyone / æ l ˈ s aɪ ə n iː /, [11] designated η Tauri (Eta Tauri, abbreviated Eta Tau, η Tau), is a star in the constellation of Taurus.Approximately 440 light-years from the Sun, it is the brightest star in the Pleiades open cluster, which is a young cluster, around 100 million years old.
