According to the star classification, G star appears to be white to yellowish in color and F stars appear blue to white in color. Both are cool stars because it has a temperature of 6,000 K and luminosity of 1,000 K, which are the characteristics of cool stars. Hotter stars have a temperature of about 40,000 K which is extremely high and the luminosity of a star is directly dependent on the star's temperature. Hot stars have high luminosity whereas low stars have low luminosity. These two stars are cooler stars.
