Until you provide a satisfactory explanation of why the stars appear to

Hell is created in people's heads but vanishes when they use their hearts and that happens each day when some people take the time out to watch the Sun come into view or disappears from view as the planet turns daily.
The slow event of polar twilight and dawn is a product of another surface rotation as those locations turn parallel to the orbital plane and to the central Sun. It is meant to elevate the observer's appreciation of the Earth's motion through space and around the Sun and this takes priority.
Celestial sphere or circumpolar motion and making judgments of the structure of the solar system is like making judgments of normal motions from a fairground carousel .This is why all the normal effects which refer terrestrial sciences and the daily and annual cycles to the motions of the Earth are lost. I have no doubt that this will provide another distraction which celestial sphere enthusiasts are looking for in order to avoid looking at the polar dawn and twilight occurring right now.
