It examines a system of five exoplanets in orbital resonance, where the periods are given in a specific ratio. The task is to calculate the ratio of equilibrium temperatures between two of these planets, Planet_D and Planet_B, based on their orbital periods and assuming they have the same albedo. The answer to this calculation is 0.83, indicating the relative thermal characteristics of the two planets."}
