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.

Surface temperature. Also, if a star has the same radius as the sun but a higher surface temperature, the hotter star exceeds the sun in luminosity. The sunâs surface temperature is somewhere around 5800 Kelvin (9980 o Fahrenheit).Thatâs 5800 degrees above absolute zero, the coldest temperature possible anywhere in the universe.etâs presume a star has the same surface temperature as the sun, but sports a larger radius. In that scenario, the star with the larger radius claims the greater luminosity. In the example below, weâll say the starâs radius is 4 solar (4 times the sunâs radius) but has the same surface temperature as our sun.
