This is the closest to a defense of geocentrism as has come into my mailbox. Of course, it isn’t a defense, but here you go:

Jonah –
It is not my intent to defend geocentrism, but I do weary of the common rebuttal that “the earth goes around the sun.” Imagine, if you will, if the earth and sun were the only two bodies in the solar system. How would one make the case that the earth went around the sun and not vice versa? And is it not curious that no one argues that the moon goes around the sun, although technically, it does? The problem is not who revolves around whom, but what frame of reference yields the simplest description of motion. Copernicus did not overthrow geocentrism so much as he provided a different reference point that made it possible to describe planetary motions as ellipses rather than epicycles and other wierd paths.
