Answer #1

  where P is Power and T is absolute temperature.

  

  
  

The power radiated at 6000K is 81000W.

Wien's displacement law states, where is peak wavelength and T is absolute temperature.

The peak wavelength is 483nm and it lies in visible region.

This is from Principles of Planetary Climate, Problem 1.13 The thick CO2 atmosphere of Venus is nearly opaque in the infrared, so observations of Venus in the infrared spectrum provide no direct information about the temperature of the ground. However, the atmosphere is nearly transparent to microwave radiation, so the microwave emission of the planet can be used to infer its surface temperature. Indeed, this is how it was inferred in the 1960s that the surface of the planet was...
