Using basic shape-factor definitions, estimate the equilibrium temperature of the planet Mars, which has a diameter of 6600 km and revolves around the sun at a distance of 225 × 10⁶ km. The diameter of the sun is 1,384,000 km. Assume that both the planet Mars and the sun act as blackbodies, with the sun having an equivalent blackbody temperature of 5600 K. Then, repeat your calculations assuming that the albedo of Mars (the fraction of the incoming radiation returned to space) is 0.15.
