Two red stars have surface temperatures of 3000 K, but Star A's luminosity is about 5% of the Sun's and Star B's luminosity is about 32,000 times the luminosity of the Sun. How much bigger is star B than star A
Star B's radius is about 800 times larger than star A's radius.
Explanation:
When the two stars that have the same surface temperature of about 3000K. The Star A has luminosity from about 5% and is that of the star B is about 32,000 times. Thus the luminosity is a characteristic of the star and the suns the Star B with a radius of 800 times will be larger than the star A in radius.
