Blue giant

A blue giant is a type of star that is very hot and massive, typically characterized by its blue color and high luminosity. These stars are part of the larger classification of stars based on their temperature and size. Blue giants usually have a surface temperature exceeding 10,000 Kelvin (as opposed to the Sun's surface temperature of about 5,500 Kelvin) and can be significantly more massive than the Sun, often ranging from about 10 to 100 solar masses.
