is 8 light minutes away from Earth.

Because the Sun is eight light minutes away from the Earth, that means that it takes light eight minutes to get from the Sun to the Earth, where the sunlight is scattered by the gases in the atmosphere, and because Rayleigh scattering is inversely proportional to the fourth power of the wavelength, this means that the shorter wavelengths, such as blue and violet, are scattered more than longer ones, like red and yellow.
