The temperature of the sun reaches about 5780 K. K stands for Kelvin and can be switched 1:1 with Celsius (C).
The sun has sa G2 temperature class and is classified as a carbon-oxygen white dwarf.
The sun is extremely hot! Most estimates think it is about 11000 degrees F. I say that these are estimates because any type of thermometer would burn and melt if we actually put in on the sun.
