Is earth a black body
WebAlthough much hotter on the inside, we can closely approximate the surface of the sun, from which its emission occurs, as a black body at a temperature of about 5800 K. The Stefan-Boltzmann equation then gives the energy flux emitted at the sun’s surface. S S = (5.67 × 10 –8 W·m –2 ·K –4 ) (5800 K) 4 = 63 × 10 6 W·m –2 WebConnected to the energy of the Earth, the R..." C.
