Sun is a black body
WebFor shorter wavelengths, the sun’s spectrum gets notably “rough” compared a black body. For instance, its peak at about 500 nm is noticeably sharp compared to a black body, and there are many more absorption artifacts in the short-wavelength region. So, the simple answer is no. But it’s quite close in the red/infrared, and is fairly close WebAs with all matter, the sun emits a “black body spectrum” that is defined by its surface temperature. A black body spectrum is the continuum of radiation at many different …
