Not that I know much about it, or even care, but the term "retrograde motion" was used in the initial message. Seemingly it was possibly referring to either revolution or rotation directions.
In some of the replys, the difference between revolution and rotation seems to have been muddied.
Revolution is the circling of the planets etc. around the sun. I believe they all revolve in the same direction, although apparent retrograde motion (as discussed by TC) does happen.
Rotation is the spinning of the planets on their axies.
Of course, there are considerable differences in the orientations of the various planets rotational axies, and the planes of their revolving around the sun.
Just my two cents worth, and probably worth no more.
