orange moon…

Saw a huge orange moon rising on the Turin-Milan motorway. Why is it orange? Apparently, this effect is caused by the atmosphere of the earth and the reason for the orange colour is due to the scattering of light by the atmosphere. When the moon is near the horizon, the moonlight has to pass through much more atmosphere than when the moon is directly overhead, so by the time the moonlight reaches your eyes, the blue, green, and purple pieces of visible light have been scattered away by air molecules. That’s why you only see yellow, orange, or red…see? (got this info from here, but there is better moon info on the NASA site)
