Question about colour of stars and planets.

    The sun appears yellow because is made of white light and blue,green,indigo gets scattered.My question is why the planets and the moon appear white with their case the same thing should happen and even they should appear yellow.

    The sun appears white if you look at it about 25 degrees or more up in the sky. Below that the Sun, Moon, Planets, and Stars have noticeable color change due to scattering of the shorter wavelength light.
