You are aware, are you not, that astronomers use an inertial reference

Awareness is the faculty of recognising basic principles,in this case
the definition and distinction of the 24 hour day from the natural
unequal day using the Equation of Time and the Sun as a reference to
facilitate the seamless transition from one 24 hour day to the next
via axial rotation and the 24 hour/360 degree equivalency.

You again to fail to answer my question.

I'll wait for you to answer that question before moving on.
