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 first list shows a few of the known stars with an estimated luminosity of 1 million L ☉ or greater, including the stars in open cluster, OB association and H II region. The majority of stars thought to be more than 1 million L ☉ are shown, but the list is incomplete. The second list gives some notable stars for the purpose of comparison.
Also, NASA notes that unlike stars that twinkle and sparkle when it’s dark out, planets, like Mars, do not flicker. Instead, they appear as steady beams and glow brighter. Instead, they appear ...
Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list. While supergiants are typically defined as stars with luminosity classes Ia, Iab or Ib, other definitions exist, such as those based on stellar evolution. [1] Therefore, stars with other luminosity classes can sometimes be considered supergiants.
Second brightest star in the night sky. Gacrux (γ Crucis) 73 [97] L/T eff: Twenty-sixth brightest star in the night sky. Polaris (α Ursae Minoris) 46.27 ± 0.42 [98] AD The current star in the North Pole. It is a Classical Cepheid variable, and the brightest example of its class. Aldebaran (α Tauri) 45.1 ± 0.1 [99] AD Fourteenth brightest ...
All of the young stars appear to be no bigger than our sun. The Webb Space Telescope is marking one year of cosmic photographs with one of its best yet: the dramatic close-up of dozens of stars at ...
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.
