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 .

Of particular note among these stars are "the dog star" Sirius, the brightest star in the sky, and four stars of the easily identified constellation Orion. Equatorial stars of the western hemisphere The equatorial region of the celestial sphere's western hemisphere includes 13 navigational stars from Gienah in the constellation Corvus to Markab ...
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 ...
Aldebaran varies in brightness from an apparent visual magnitude 0.75 down to 0.95, making it the brightest star in the constellation, as well as (typically) the fourteenth-brightest star in the night sky. It is positioned at a distance of approximately 65 light-years from the Sun. The star lies along the line of sight to the nearby Hyades cluster.
