Supergiant Stars - Well Known Examples

Well Known Examples

Supergiants are rare and short-lived stars, but their high luminosity means that there are many naked eye examples, including some of the brightest stars in the sky. Rigel is the brightest star in the constellation Orion and a typical blue-white supergiant, Deneb is the brightest star in Cygnus and a white supergiant, Delta Cephei is the famous prototype Cepheid variable and a yellow supergiant, while Betelgeuse and Antares are red supergiants. μ Cephei is one of the reddest stars visible to the naked eye and one of the largest in the galaxy. Rho Cassiopeiae is a naked eye variable, a yellow hypergiant, and possibly the most luminous naked eye star.
