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… WebApr 5, 2024 · Satellites measure the brightness of Earth’s atmosphere, and then scientists work hard to convert that information to temperatures using computer models, which are … WebThe average temperature of the Earth’s surface is about 288 K.
