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 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 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 ...
Rare blue supergiant stars are some of the hottest, brightest stars in the universe. But other distant supernovas have shown that before they exploded, stars ejected dense clouds decades beforehand.
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 ...
HD 93129 Aa is the closest O2 supergiant to Earth. [13] That volume of space is home to many other massive and luminous stars. HD 93128, yet another O3.5 main sequence star, is only 24' away within Trumpler 14, and HD 93250 and HD 93205 are two more O3.5 stars in the larger Trumpler 16 cluster around η Carinae.

It is placed in subgroup SRc; these are pulsating red supergiants with amplitudes around one magnitude and periods from tens to hundreds of days. [8] Betelgeuse typically shows only small brightness changes near to magnitude +0.5, although at its extremes it can become as bright as magnitude 0.0 or as faint as magnitude +1.6.
