The planet Mars has a diameter of 6772 km, and it orbits the sun at a distance of 227.9 x 10^6 km. If the sun is assumed to radiate like a blackbody at 5760 K, and Mars has an albedo of 0.15 ( reflects 15% of incident radiation back to space), estimate the average temperature of the Martian surface. Ignore the effects of the thin Martian atmosphere.
