If I am not mistaken the animation portrayed the moon at perigee when the sun was on the opposite side or when the face of the moon was dark, and at apogee when the sun was behind the earth and the face of the mood was fully lighted up.

I am lacking some understanding here. I would have thought that the moon would have been pulled into perigee with the sun behind the earth and the moon face lit up.

What am I missing.
