Ah, but that just raises more issues.  Geosynchronous satellites are by definition pegged to a relative spot over the earth&#x27;s surface.  And the earth spins constantly, inside and out.  The question is, is there any difference between the core spinning slightly slower, vs. the crust spinning slightly faster (assuming zero acceleration)?<p>To a godlike observer outside of the plane of the ecliptic, I&#x27;m not sure the idea of one being stationary and the other &quot;slipping&quot; in some direction even has meaning.
