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). The solar constant (GSC) is a flux density measuring mean solar electromagnetic radiation (total solar irradiance) per unit area. It is measured on a surface perpendicular to the rays, one astronomical unit (au) from the Sun (roughly the distance from the Sun to the Earth). The solar constant includes … See more Solar irradiance is measured by satellites above Earth's atmosphere, and is then adjusted using the inverse square law to infer the magnitude of solar irradiance at one Astronomical Unit (au) to evaluate the solar constant.
