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]
Around Dec. 14, Jupiter will be visible in the night sky between the nearly full moon and a reddish-orange star called Aldebaran, which shines brightest in the Taurus constellation and can be seen ...
If this object were 10 parsecs away from Earth it would appear nearly as bright in the sky as the Sun (apparent magnitude −26.744). This quasar's luminosity is, therefore, about 2 trillion (10 12) times that of the Sun, or about 100 times that of the total light of average large galaxies like our Milky Way. (Note that quasars often vary ...
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.
An asteroid in our solar system will temporarily block the light of Betelgeuse, one of the brightest stars in the night sky, Monday evening and early Tuesday morning.

Of the ten brightest stars in the night-time sky by apparent magnitude, [nb 1] Alpha Eridani is the hottest and bluest in color because it is spectral type B. Achernar has an unusually rapid rotational velocity, causing it to become oblate in shape. The secondary is smaller, is spectral type A, and orbits Achernar at a distance of 7.35 AU.
