Saw this through the break in the clouds and it was as lovely as could be. Venus is moving in behind the central Sun and will transition to an twilight appearance once more whereas Jupiter will move back through the night..

While it is wonderful to predict the astronomical events like the sight of Venus and Jupiter in close proximity using a rotating celestial sphere, don't try to model the motions of the Earth, the other planets and solar system structure on that RA/Dec framework -

So much more to enjoy once the future software program emerges that substracts the daily rotation of the planet and allows the planets,including our own, to travel freely in context of our motion and that of the central Sun along with the motions of the satellites of each planet around their parent.

Is this the sort of software you need?


No.

We can only see to the left and right of the stationary Sun during a total eclipse otherwise humanity references the motions of the faster moving Mercury and Venus after they enter the circle of illumination (dusk) or just as they exit it (dawn). The transition of the inner planets from right to left as they move behind the Sun or from left to right as they pass between the Earth and the Sun really has only one useful graphic to capture a stationary Sun and the looping motions of the inner planets -

The direct/retrogrades motions of the inner planets reflect an actual looping motion in comparison to the illusions of outer planetary direct/retrograde motion -

Proof of the Earth's orbital motion is tied up with the physical descriptions of the smaller actual loops of the inner planets. It requires that the background stars are actually seen to transition from a twilight to dawn appearance hence it is easily identified why the original Sun centered astronomers had so much trouble with Venus and Mercury using a moving Sun framework that you have in your Youtube graphic -


". . . the ancient hypotheses clearly fail to account for certain important matters. For example, they do not comprehend the causes of the numbers, extents and durations of the retrogradations and of their agreeing so well with the position and mean motion of the sun.

I could say that you at least got out of your rotating celestial sphere into which all motions are set but unfortunately you didn't -

This is not a test but a project.
