Answer by Stilez for Why is the Sun approximated as a black body at ~ 5800 K?
A point worth mentioning, is that the temperature of the black body may be a bit surprising. This graph might be useful:graph from libretextsThe core of the sun is many millions of degrees. But we...

Answer by jkej for Why is the Sun approximated as a black body at ~ 5800 K?
As a complement to the other answers, I'd like to point out that if you measure the solar spectrum at a very high resolution, you see very large variations in spectral radiance over very short...

The solar constant ($S$) is the energy received per unit area perpendicular to the rays at 1 AU distance (see wikipedia). Thus, mathematically, it represents the total energy emitted by the sun divided...

Answer by J. Murray for Why is the Sun approximated as a black body at ~ 5800 K?
Yes - the integral of the spectrum you refer to gives the total power per unit area emitted from the surface of the sun. If you multiply that by a factor of $\left(\frac{\text{Solar Radius}}{1\text{...

Why is the Sun approximated as a black body at ~ 5800 K?
Apparently spectral solar radiation is approximated by a black body at 5800 K. The spectral black body distribution (Planck distribution) is shown below (from Incropera, Fundamentals of Heat and Mass...
