WebThe hotter the flame the bluer it gets. Blue giants are typically known as some of the hottest objects in the galaxy. Our sun, a yellow star, generally burns at a temperature of 6000K (that’s Kelvins!) which is an average star temperature. In comparison, blue giants burn at a temperature of roughly 20,000K – 24,000K.
A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M☉)) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K (4,700 °C; 8,500 °F) or lower.
