Default What the direct/retrograde motion of Venus looks like

The dovetailing between orbital perspectives and timekeeping and
specifically proof of the Earth's annual circuit of the Sun is founded on
the transition from an evening to a morning appearance of the stars close
to the orbital plane or the faster moving Venus and Mercury.

I cannot imagine any adult being unable to make the call on the transition
of the stars from an evening to morning appearance due solely to the
orbital motion of the Earth. As a location passes through the circle of
illumination it sees all objects to the left of the Sun so that when an
observer continues to rotate they exit the circle of illumination and see
the stars and celestial objects to the right of the Sun.


This is utterly incomprehensible - and I seriously doubt it's because
English is my second language. If you can rephrase to readable English I
could possibly figure out if I agree with you. But I guess not.

"dovetailing"?
"circle of illumination"?
"direct/retrogrades resolution"?



Here, let me help you with the English language -

Let me help you also with the circle of illumination representing the circle at right angles to the orbital plane

Direct/retrograde motions are for astronomers who can now distinguish how we see the faster moving planets from the slower moving planets as seen from a moving Earth.


Illusory open-ended loops of the slower planets where the Sun is never the center of the loop -

Actual loop of the faster planets where the Sun is always at the center -

Any more dull people who need English or astronomical lessons ?.
