They are just different coordinate systems for answering different
questions on a sphere. One allows you to predict where to find a
position on the Earth and the other where to find a star in the sky.



Thanks for the very Brexit-like waffle as the Earth's maximum Equatorial speed is 1037.5 miles per hour and a full 24,901 miles for a complete 360 degree rotations or do you not do these type of equations where is full rotation is extrapolate from a proportion where one hour equates to 15 degrees of rotation ?.

The simple fact is that Newton hung his agenda and conclusion on RA/Dec and you haven't an effin clue how he did it even when it is shown to you exactly what he tried to do -

"That the fixed stars being at rest, the periodic times of the five primary planets, and (whether of the sun about the earth, or) of the earth about the sun, are in the sesquiplicate proportion of their mean distances from the sun.... for the periodic times are the same, and the dimensions of the orbits are the same, whether the sun revolves about the earth, or the earth about the sun." Newton

More Brexit-like twaddle that eventually snowballed into a nightmare for astronomy but suits theorists who have zero interest in the antecedent statements of genuine astronomers and through which mathematicians exploited an opening in astronomy.

No wonder your nation is trying to square impossible circles because academic dummies have tried to do that for centuries by trying to bypass the Lat/Long system and the 24 hour system for one rotation.
