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
Polaris is a star in the northern circumpolar constellation of Ursa Minor. It is designated α Ursae Minoris (Latinized to Alpha Ursae Minoris) and is commonly called the North Star or Pole Star. With an apparent magnitude that fluctuates around 1.98, [3] it is the brightest star in the constellation and is readily visible to the naked eye at ...
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 .
A star chart of the entire Northern Sky, centered on the north celestial pole. The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator. This arbitrary sphere appears to rotate westward around a polar axis due to Earth's rotation.
Alsciaukat is also a variable star, ranging in brightness by 0.05 magnitude over 25 to 30 days from its baseline magnitude of 4.25. [15] Lynx is rich in double stars. [2] The second brightest star in the constellation is 38 Lyncis at magnitude 3.8. When viewed through a moderate telescope, the two components—a brighter blue-white star of ...
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 .
Spica is a binary blue-white star pair that appears as a single point of light from Earth, and is commonly if incorrectly referred to as a single star. The star system is 250 light years away and has an apparent magnitude of 1.04. [13] It is the brightest star in the constellation Virgo, and is the 15th brightest star in the night sky. [14]
