Here's one to contemplate: does the Moon orbit the Earth primarily with the Sun slightly perturbing its path around the Sun? Or does the Moon orbit the Sun primarily, and the Earth just happens to be synchronized with it, with the Earth and Moon slightly perturbing each other's solar orbits?

The orbital speed of the moon around the sun is about 30X that of its orbital speed about the earth. There is no 'retrograde' motion in its path around the sun, just a slalom-like wiggle.
