Poor misunderestanding boy. Consider the cirumstance when the moon's
shadow is cast on the earth. Every movement then, until it's 90
degrees displaced, has an acceleration component away from the sun.
For that matter, 180 degrees later, when it lies along the earth path,
moving toward the moon, it has an acceleration vector with a component
away from the sun.

Basic mechanics.

Heavens, I teach psych, and know this stuff.
