Why does the Moon appear in different colours?

          Poets often describe the silvery moon. But, the Moon doesn’t always appear silvery; it is sometimes white, sometimes yellow, grey or even red at times.

          When the Moon is low in the sky, it is closer to the horizon. The light that travels through the air scatters near the horizon as it passes through a thick layer of atmosphere. As a result, the Moon looks yellowish or orange at times. When the Moon is high in the sky, the scattering effect is much lesser and it appears whitish. During a total lunar eclipse, the Moon appears to be red; this too is caused by the scattering of light. The colours of the Moon give us clues about the minerals present on its surface.
