What brilliant astronomers you all are ! -

"The Earth's rotation velocity at the equator is 1,674.4 km/h. Just by
standing on the equator, you're already traveling 1,674.4 km/h in a
circle. This rapid rotation flattens out the Earth into an oblate
spheroid; sort of a squished ball. Points along the equator are
actually further from the center of the Earth than at the poles."

The correct value is in the tables where the equatorial speed of
111.32 km represents 1 degree and 4 minutes of rotation corresponding
to 1669.8 km per hour and a full 360 degree/40,075 equatorial
circumference in 24 hours -

Astronomy is totally pointless without the basic planetary facts and
being unresponsive to the continuation of this tragedy is pretty much
the worst trait of it all,there is no goodness or intelligence
involved, for even when it explained how the constant return of a star
is explained within the calendar system making it useless for
descriptions of planetary dynamics,you still insist that the Earth is
rotating at the center of a celestial sphere by equating one apparent
rotation with the other.

That is only true with respect to the earth. With respect to the sun
you are not making a circle, you are making a long wavy path around

If you understood frames, this would be obvious to you, too.
