The sun has a surface temperature of 5,500 K, typical for a yellow star. Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star.The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.Stars are fuelled by the nuclear fusion reactions at their core.ed stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star.

Cooler still are the orange stars. The coolest stars appear red. That's how the spectrum of a star is related â¦ to its surface temperature. The reason is that the hotter the star, the shorter the wavelength at which the light is most intense in its spectrum. Blue light is of shorter wavelength than red.he coolest stars appear red.
