A. Calculate a realistic estimate for the temperature at the surface of Mercury using the black body radiation formula.  Use the following facts.

Radius of Mercury: 2440 km.

Distance of Mercury from the sun: 5,820,000 km.

Note: Mercury does not rotate on its axis.  Please calculate the temperature on the sunny side!  You may assume that the dark side is very cold (i.e. near T = 0 K).

Temperature = _________________.

B. What wavelength is the peak of the black body emission from Neptune?

Wavelength = _____________________ .
