The sun is not yellow or orange as we see in books and movies. It emits all the colours in the visible spectrum (also in other spectrums as well) making it white!

    Could also be redshift too. I don’t know enough about it to know if we’d notice it over such a short distance and of a constant source, though. Definitely noticeable as reciprocity failure during long exposures in photography.

      No, that’s not at all what redshift is.

      And neither redshift nor dopplershift would have that much effect on light at the speeds we’re talking about.

      Besides the sun’s color on earth it’s not a shift of wavelengths, it’s a subtraction of wavelengths, as you easily can see in a spectrogram.

      Do we experience Doppler shift with our own sun? I would assume as we are in a stable orbit we wouldnt
