Have you ever wondered why the moon is more orange or yellow in color when it first rises at night? This effect is caused
by the atmosphere of the earth. The reason for the orange color is due to the scattering of light by the atmosphere. When
the moon is near the horizon, the moonlight must pass through much more atmosphere than when the moon is directly overhead.
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.
