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.
The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
The nearest white giant. Capella A 42.919 ± 0.049 [9] G8III [9] 11.98 ± 0.57 [9] 2.5687 [9] 0.03 [10] The nearest yellow giant, together with Capella A. With a magnitude of 0.08, [11] the Capella star system is the 6th-brightest star in the night sky. Capella B G0III [9] 8.83 ± 0.33 [9] 2.48 [9] 0.16 [10] The nearest yellow giant, together ...
The star, known as WOH G64, is 160,000 light-years from Earth in the Large Magellanic Cloud, a small neighboring galaxy that orbits the Milky Way. ... WOH G64 is a red supergiant star 2,000 times ...
Betelgeuse is a red supergiant star about 700 light-years away that serves as the shoulder in the Orion constellation, according to NASA. Given its intense luminosity, Betelgeuse is what ...
Nearest red giant: Arcturus: 36.7 light-years (11.3 pc) Nearest supergiant: Canopus: 309 light-years (95 pc) While it is frequently described as a yellow supergiant, especially in evolutionary terms, [16] it is classified as a bright giant based on spectrum. [17] [16] List of nearest supergiants: Nearest hypergiant: μ Cephei (Herschel's Garnet ...
Supergiants typically have surface gravities of around log(g) 2.0 cgs and lower, although bright giants (luminosity class II) have statistically very similar surface gravities to normal Ib supergiants. [20] Cool luminous supergiants have lower surface gravities, with the most luminous (and unstable) stars having log(g) around zero. [9]
It is one of the sky's few naked-eye class O-type stars as well as one of the closest to Earth. [12] It is a blue supergiant , one of the most luminous stars in the Milky Way . Visually it is over 10,000 times brighter than the Sun , but its high temperature means that most of its radiation is in the ultraviolet and its bolometric luminosity is ...
