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]
Arcturus is the brightest star in the constellation of Boötes. With an apparent visual magnitude of −0.05, Arcturus is the brightest star in the northern celestial hemisphere and the fourth-brightest star in the night sky, [14] after Sirius (−1.46 apparent magnitude), Canopus (−0.72) and α Centauri (combined
It appears prominently in the northern sky during the Northern Hemisphere's summer, and the whole constellation is visible for at least part of the year to observers north of latitude 42°S. [ 11 ] [ n 2 ] Its main asterism consists of six stars, [ n 3 ] and 73 stars in total are brighter than magnitude 6.5. [ 11 ]
Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years (7.7 parsecs) from the Sun, and one of the most luminous stars in the Sun's neighborhood.
Northern lights should be visible on Thanksgiving and Black Friday from New York to Idaho thanks to an incoming solar storm, according to NOAA. Northern lights forecast: Auroras may be visible ...
The second brightest star is Scheat, a red giant of spectral type M2.5II-IIIe located around 196 light-years away from Earth. [28] It has expanded until it is some 95 times as large, and has a total luminosity 1,500 times that of the Sun. [ 29 ] Beta Pegasi is a semi-regular variable that varies from magnitude 2.31 to 2.74 over a period of 43.3 ...
Three of these stars are in Crux making it the most densely populated as to those stars (this being 3.26% of these 92 stars, and in turn being 19.2 times more than the expected 0.17% that would result on a homogenous distribution of all bright stars and a randomised drawing of all 88 constellations, given its area, 0.17% of the sky).
Capella is the brightest star in the northern constellation of Auriga. It has the Bayer designation α Aurigae, which is Latinised to Alpha Aurigae and abbreviated Alpha Aur or α Aur. Capella is the sixth-brightest star in the night sky, and the third-brightest in the northern celestial hemisphere after Arcturus and Vega.
