Question:
The rotational velocity of the earth around the sun exceeds that of the moon around the earth therefore the moon never moves retrograde in its solar orbit and its actual path about the sun resembles a sine wave but giving the appearance of a circular path about the earth. Are my conclusions correct and if not why not?

Replies:
Dear Robert,

Without spending the time on the math, I believe you are right. And the sine wave path of the Moon about the Sun would be hard to see at the scale of the Earth's orbit.

Good question!
