There are a couple of great Khan Academy videos, that demonstrate how the phases of the moon work, and put the scale in perspective: www.khanacademy.org/science/cosmology-and-astronomy/earth-history-topic/moon-phases-and-eclipses/v/intro-to-moon-phases Below, the first video shows the moon, as we see it, through all its phases. The second video shows the the far side of the moon (the side we never see), from the perspective of space, and in relation to the earth. |
