WebThe energy flux associated with solar radiation incident on the outer surface of the earth's atmosphere has been accurately measured and is known to be 1368 W/m2. The diameters of the sun and earth are 1.39 × 109 and 1.27 x 107 m, respectively, and the distance between the sun and the earth is 1.5 x 1011 m. WebBecause the Sun (or any star) is a sphere of radius R, we state it has a surface: A = 4 π R2. With the Sun's radius R = 6,96 × 108m, we can compute its surface temperature T: There is also another way to get the value of T by using Wien's law: λmaxT = b where λmaxis the most intensive wavelength, and b the Wien constant (b = 2,90 × 10-3mK).
