Celestial navigation (quiz)

The Aids to Navigation (quiz) thread, which I've been mostly luking on for a while, has inspired me to create a similar quiz for Celestial nav, mostly for selfish reasons.

I'll start, also sort of at the beginning:

What direction does the Earth revolve around the sun?
What direction does the sun revolve around the Earth?
What direction does the moon revolve around the Earth?

Please specify CW or CCW and specify what pole you're looking at.

Thanks a lot. So, does the RA have more of an association with SHA then (which is measured from the Meridian of Aries)? This seems to be academic anyway, if it's not being used by navigators. Now I have to wrap my head around all these meridians....(prime, Aries, geo, celestial...not to speak of the ecliptic etc.) Very confusing, but fascinating. Wish I started this long ago.
Those navigators of old were a very clever lot. Puts most of us to shame.
