Rigel, a blue supergiant star in the constellation Orion, has a surface temperature of approximately 11,000 to 12,000 Kelvin. This high temperature contributes to its bright blue color and significant luminosity, making it one of the most prominent stars in the night sky. Rigel's intense heat is a result of its massive size and rapid rate of nuclear fusion in its core.
