  2. List of brightest stars - Wikipedia

    en.wikipedia.org/wiki/List_of_brightest_stars

    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]

    en.wikipedia.org/wiki/List_of_most_luminous_stars

    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 ...

  5. Apparent magnitude - Wikipedia

    en.wikipedia.org/wiki/Apparent_magnitude

    In 1856, Norman Robert Pogson formalized the system by defining a first magnitude star as a star that is 100 times as bright as a sixth-magnitude star, thereby establishing the logarithmic scale still in use today. This implies that a star of magnitude m is about 2.512 times as bright as a star of magnitude m + 1.

  6. Polaris - Wikipedia

    en.wikipedia.org/wiki/Polaris

    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 night. [15] The position of the star lies less than 1° away from the north celestial pole, making it the current northern pole star.

  7. Magnitude (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Magnitude_(astronomy)

    An illustration of light sources from magnitude 1 to 3.5, in 0.5 increments. In astronomy, magnitude is a measure of the brightness of an object, usually in a defined passband. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus. Magnitude values do not have a unit.

  8. List of nearest bright stars - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest_bright_stars

    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.

  9. Canopus - Wikipedia

    en.wikipedia.org/wiki/Canopus

    Canopus is too bright to be included in the normal observation runs of the Gaia satellite and there is no published Gaia parallax for it. [56] At present the star is drifting further away from the Sun with a radial velocity of 20 km/s. Some 3.1 million years ago it made the closest approach to the Sun at a distance of about 172 ly (53 pc).
