WebAnd we can see: our Sun behaves very much like a perfect blackbody (Fig. 7). Because the Sun (or any star) is a sphere of radius R, we state it has a surface: A = 4 π R 2. With the Sun's radius R = 6,96 × 10 8 m, we can compute its surface temperature T: There is also another way to get the value of T by using Wien's law: λ max T = b WebAs the composition changes due to using up the hydrogen, the other parameters of the Sun such as its radius, temperature, and luminosity must change as well. According to the figure below, the solar radius has increased by about 12% over its lifetime, the surface temperature has increased by about 20%, and the luminosity (4 p R 2 s T 4 ) has increased by 30%.
