    This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [95] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [101] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [102]

  3. List of nearest stars - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest_stars

    The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A , which is also the brightest star in Earth's night sky ; its white dwarf companion Sirius B is the hottest object among them.

  5. List of nearest supergiants - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest_supergiants

    This is a list of the nearest supergiant stars to Earth, located at a distance of up to 1,100 light-years (340 parsecs) from Earth. 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 ...

  6. Giant star - Wikipedia

    en.wikipedia.org/wiki/Giant_star

    A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. [1] They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III. [2]

  7. Aldebaran - Wikipedia

    en.wikipedia.org/wiki/Aldebaran

    It has a surface gravity of 1.59 cgs, typical for a giant star, but around 25 times lower than the Earth's and 700 times lower than the Sun's. Its metallicity is about 30% lower than the Sun 's. Measurements by the Hipparcos satellite and other sources put Aldebaran around 65.3 light-years (20.0 parsecs) away. [ 10 ]

  8. Hamal - Wikipedia

    en.wikipedia.org/wiki/Hamal

    With an apparent visual magnitude of 2.0, [2] it is the mean 50th-brightest star in the night sky. Based upon parallax measurements made with the Hipparcos astrometry satellite, [14] [15] Hamal is about 65.8 light-years (20.2 parsecs) from Earth. [1] It is a giant star that may host an orbiting planet with a mass greater than Jupiter. [8]
