Does "turns once to the central sun" mean the same thing as
"completes one orbit of the sun"? If so, please do not make up new
phraseology for well-known phenomena.

Here you are apparently using a different meaning of "turn". Are you
now claiming that the moon does not turn once to the Earth as a
component of its orbital motion, as planets do when orbiting the sun?

That is false, as I pointed out before, and which you are apparently
carefully ignoring. Every point on the moon's surface experiences a
day-night cycle- it sees the sun rise and set. There are two possible
ways this can occur- either the sun orbits the moon (I doubt you would
support that view) or the moon rotates..

Nonsense. The moon does not have a north polar star, but its south
pole points at Delta Doradus.

That is completely ridiculous. Polaris and Kochab were the same
distance from the apparent point Earth;s north spin pole pointed at in
the night sky.
Axial precession *is* a "long term axial trait". If it were an
annual phenomenon there would not be a given pole star in a given
historical epoch. Any sailor worth his salt water will laugh long and
hard at you.

Nothing to do with Newton or whether the moon spins.

I notice that you are carefully ignoring my earlier post. Here, let
me reproduce it for you:

I would like a straight answer to a straight question.

Of course I did, just to make sure you hadn't got hold of something
not congruent with reality.
Are you now saying this is unique to Uranus, or not?
Did you intend your statement "It is a 100% observational certainty
that as a planet orbits the central Sun it turns once as a component
of its orbital motion" to apply to other planets, or not?
Please clarify.

Sorry, but you appear to be using nonstandard meanings of north,
south, east and west here.

I had not noticed you asking a question. I asked you a question for
clarification.

Yes, thank you just the same, I already looked at it. It is not new
to me and takes no getting used to.
I'd very much like a direct answer to my original question, please.
I will even reproduce it here for you -
"So now you're saying that completing an orbit equals rotating once-
do I have that correct? "
While you're formulating a response, please ponder this:
