Proving the Earth's orbital motion.

The RA/Dec observers try their level best to equate circumpolar motion to daily rotation and that uses up the observation of the motion of the stars -

The astronomers at the time of Copernicus were using the motion of the Sun through the constellations along with the motions of the other planets for prediction purposes but they never used a North/South motion of the Sun by inventing a celestial Equator -

"Moreover, we see the other five planets also retrograde at times, and
stationary at either end [of the regression]. And whereas the sun
always advances along its own direct path, they wander in various
ways, straying sometimes to the south and sometimes to the north; that
is why they are called "planets" [wanderers]. Copernicus


The most accurate question a student could ask is why some stars disappear as an evening appearance, remain out of sight and then return as a morning appearance insofar as this is proof of the Earth's orbital motion -

The simple act of removing the relationship of daily rotation to circumpolar motion and using the orbital motion of the Earth to account for the changing relationship between the fixed stars and the central Sun is paramount and seen in in actuality -

Gerald, that is not the case and you know it. Why do you promote such crap?

Because suckers like you give him the recognition and legitimacy that
he craves.

With just a simple and single adjustment where the circumpolar conclusion is removed and the focus changes to the orbital motion of the Earth, affirmation that the Earth orbits a central Sun is found in their transition from an evening to morning appearance.

In intellectual matters it is not how much damage a person can inflict on another , it is how much a person is willing to suffer for their own values that always wins in time. The military person following your response doesn't have the cop-on to realize that the strongest military countries can't compete when a population won't stand for injustice and likewise the same with academics within the walls of universities and colleges. Go back to the relativity forum where you will fit right in and get false satisfaction from screaming at others who will scream right back based on a misunderstanding about timekeeping.

Utter nonsense: right back to Ptolemy's Almagest, the positions of stars were mapped using a celestial sphere with an equator, and North/South motion of the Sun in the sky is obvious to anyone who ever looked at the sky in summer and winter.

Gerald was shocked when he recently saw a star map with the celestial Equator across the middle and the Ecliptic swinging North and South across it. This is because he never looks at the sky, or apparently, at a star map until recently, he can't think in 3D, and bases his bizarre rants on random gifs and youtube videos instead.

Because he's broken. You're trying to argue with the guy standing on
the soapbox at the park ranting about aliens.

What is the rotation period of the Earth?

Professional astronomers, and scientists in general, will in fact answer "23
hours and 56 minutes" to that question.

As that is what he means by "equate circumpolar motion to daily rotation", even
if something _else_ "is not the case" (for example, no astronomer would claim
that the period of the apparent motion of the stars equals the length of the
day; they know the two are four minutes different) I am puzzled by your comment.

Maybe if he had said "the Earth's rotation" instead of "daily rotation", his
meaning would be clearer to you?

You people are afflicted with mistakes made centuries ago which assigns dynamical significance to circumpolar motion -

The only dynamical significance is the changing relationship between the stars and the Sun due to the orbital motion of the Earth and specifically the annual transition of some stars from an evening to morning appearance -

It is then and only then you discover the sequence of reasoning which equates 1461 rotations of the Earth to 4 orbital circuits (close proximity) as an expression of an ancient observation -

".. on account of the procession of the rising of Sirius by one day in the course of 4 years,.. therefore it shall be, that the year of 360 days and the 5 days added to their end, so one day shall be from this day after every 4 years added to the 5 epagomenae before the new year" Canopus Decree 238 BC

Within the close proximity is the actual resolution for the Precession of the Equinoxes as it comes from the same orbital drift responsible for the first annual appearance of Sirius after four cycles of 365 days.
