Division 10 knows that the reason that we see the moon with a glow, is because the light of the sun is reflecting off of the moon.  We think of the moon as a mirror.  In the case of the moon, it’s really a bad mirror. Because the moon is made of such dark rock, it reflects only about 12% of the light that hits it. The amount of light that gets bounced back to earth also depends on the time and place of the orbit of the moon.  When the moon’s orbit puts it in direct forward facing to the earth, we get a larger amount of light bounced back.
