Red supergiant
stars with a supergiant luminosity class
(Redirected from Red supergiants)
A red supergiant (RSG) is a larger and brighter type of red giant star. Red supergiants are often variable stars. They are between 100 to 1,600 times bigger than the Sun. Examples of a red supergiant star include Antares, 119 Tauri, Betelgeuse, Epsilon Pegasi, and VV Cephei A. Most red supergiant stars explode as supernovae. Some of the brightest become Wolf-Rayet stars before they explode.[1]
Red supergiants are stars are some of the brightest stars. They are also the largest stars in the universe. Betelgeuse and Antares are the brightest and best known red supergiants. They are also the only first magnitude red supergiant stars.
