EXTRA CREDIT (Four points) – **Note: No partial credit – no exceptions*** Suppose that you discover a new exoplanet within a distant solar system. The incoming flux of radiation from the host star at the exoplanet is the same as that of Earth (Sr = 1370 W m-2), however the greenhouse effect of this exoplanet ( = greenhouse effect = 99 K) is triple that of the Earth. What would the planetary albedo (A) of this exoplanet have to be in order for the average surface temperature () of this exoplanet to be equal to that of Earth ( = average surface temperature = 288 K)? Relevant equations and constants of interest:
