No, that's what I meant when I said above, "Not only that, to the extent that they're geocentric, they're also sun-centric. To the extent that they are not both, they are not geocentric."
Now that I think of it, are you familiar with the annual variation of stellar parallax, first reported in 1729? A very famous cycle
