Working out exactly which stars were or will be the brightest at any given point in the past or future is difficult since it requires precise 3D proper motions of large numbers of stars and precise distances. [1] This information only started to become available with the 1997 Hipparcos satellite data release. [1]
The Sun is the brightest star as viewed from Earth, at −26.78 mag. The second brightest is Sirius at −1.46 mag. For comparison, the brightest non-stellar objects in the Solar System have maximum brightnesses of: the Moon −12.7 mag [1] Venus −4.92 mag; Jupiter −2.94 mag; Mars −2.94 mag; Mercury −2.48 mag; Saturn −0.55 mag [2]
The Yale Bright Star Catalogue has been steadily enhanced since the Yale astronomer Frank Schlesinger published the first version in 1930; even though the YBS is limited to the 9110 objects already in the catalog, the data for the objects already listed is corrected and extended, and it is appended with a comments section about the objects. The ...
Alpha Caeli (α Cae, α Caeli) is the brightest star in the constellation Caelum. It is in fact a binary star, made up of a F-type star of magnitude 4.46 and a red dwarf of magnitude 12.5. They are separated by 6.6" in the sky. Parallax measurements by the Gaia spacecraft imply a distance of 20.4 pc (67 ly) to Alpha Caeli.
Beta Ceti (β Ceti, abbreviated Beta Cet, β Cet), officially named Diphda / ˈ d ɪ f d ə /, [14] is the brightest star in the constellation of Cetus.Although designated 'beta', it is actually brighter than the 'alpha' star in the constellation, Menkar, by half a magnitude.
α Gruis (Latinised to Alpha Gruis) is the star's Bayer designation. (Its first depiction in a celestial atlas was in Johann Bayer's Uranometria of 1603. [14]) It bore the traditional name Alnair or Al Nair (sometimes Al Na'ir in lists of stars used by navigators), [15] from the Arabic al-nayyir "the bright one", itself derived from its Arabic name, al-nayyir min dhanab al-ḥūt (al-janūbiyy ...
This star has a stellar classification of G7 V, [8] indicating that it is a G-type main sequence star that is generating energy by fusing hydrogen into helium at its core. It is of similar size but slightly cooler than the Sun, with 96.4% of the mass, 96% of the radius, and 81% of the Sun's luminosity. [ 4 ]
Gamma Velorum is a quadruple star system in the constellation Vela.This name is the Bayer designation for the star, which is Latinised from γ Velorum and abbreviated γ Vel.At a combined magnitude of +1.72, it is one of the brightest stars in the night sky, and contains by far the closest and brightest Wolf–Rayet star.
