SUMMARY
The discussion focuses on calculating the ratio of emitted radiation to absorbed solar radiation on Jupiter, which has a black body temperature of 125K. The Stefan–Boltzmann law is confirmed as the correct approach, emphasizing the use of irradiance rather than area. The temperature difference of 20K above the expected value from absorbed solar radiation is critical for this calculation. Participants suggest using the formula W = sigma * temp^4 to derive the necessary ratio.
