Recently I wrote a piece which answered question about size of sun and few other tidbits, this time around I received an email from one of my readers and he asked me to write “what is the temperature of then Sun?” Well, it did not take me much time, because I knew the answer. So here it goes –
5770 Kelvin is the surface temperature. But the solar atmosphere gets much much hotter, up to ten of millions of kelvins. The inside temperature is also much hotter, by the way this is where the nuclear fusion takes place.
Kelvin is a unit of measurement, please refer to Wikipedia Kelvin Page for more information.
