Default Polar astronomy

With Mars or Jupiter, their real orbits around the Sun have retrograde
motion added to them; with Venus and Mercury, the retrograde motion is
caused by their real orbital motion on the opposite side of the Sun.

That remark about how you know better? I apologize and withdraw it.
