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 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. The largest object within the 20 light-years is Procyon.

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] 2.483 ± 0.007 [9] 0.16 [10] The nearest yellow ...
Stephenson 2, also known as RSGC2 (Red Supergiant Cluster 2), is a young massive open cluster belonging to the Milky Way galaxy. It was discovered in 1990 as a cluster of red supergiants in a photographic, deep infrared survey by the astronomer Charles Bruce Stephenson, after whom the cluster is named.
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 ...
Nasa has issued an alert for a stadium-sized asteroid set to make a close approach to Earth on Tuesday.. The 2024 ON asteroid measures 290 metres (950 feet) across and will come within 1 million ...
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] Hotter ...
The Alpha Persei Cluster, also known as Melotte 20 or Collinder 39, is an open cluster of stars in the northern constellation of Perseus. To the naked eye, the cluster consists of several blue-hued spectral type B stars. The most luminous member is the ~2nd magnitude yellow supergiant Mirfak, also known as Alpha Persei.
