Earth brightness temperature
To find the effective (blackbody) temperature of a planet, it can be calculated by equating the power received by the planet to the known power emitted by a blackbody of temperature T. Take the case of a planet at a distance D from the star, of luminosity L. Assuming the star radiates isotropically and that the planet is a long way from the star, the power absorbed by the planet is given by treating the planet as a disc of radius r, which intercepts som… Web1C Microwave Brightness Temperatures GES DISC.

(In fact, very warm. Average global temperatures may have been as high as 140 F°.) Various complex bio-geological feedback loops have steadily decreased the greenhouse effect precisely because the Sun is getting brighter.
