Just to give you a running start, I thought I'd include a few other, relatively non-controversial, astronomical observations, with the request that you explain how your model accounts for them:
The Hertzsprung-Russel mass-luminosity relationship. According to your model, all stars (with minor exceptions) are at the same distance from earth: 4.5 ly. This means that all stars' apparent magnitude is equal to their absolute magnitude, and therefore their apparent luminosity is the same as their intrinsic luminosity. This means that the Hertzprung-Russel mass-luminosity relationship is broken, and there is therefore no relationship between a star's mass and its luminosity, or between its temperature and its luminosity. Therefore some other explanation is necessary for the different temperatures of stars. What is that explanation?
Galaxies. Since galaxies are all the same distance from the earth as the stars are (4.5 ly), either they're not made of stars at all (and hence are "nebulae"?), or they're made of extremely non-luminous stars. But stars have been resolved in some nearby galaxies, e.g., the Magellanic clouds. Presumably these are really tiny stars? Since their apparent luminosity is the same as their intrinsic luminosity…
Cosmic elemental abundances. (Is evopeach out there somewhere?). Presumably Bill's geocentric universe precludes a big bang, and therefore precludes primordial nucleosynthesis. Therefore, one needs some other explanation for the eerie concordance between the observed cosmic microwave background radiation and the predicted abundances of hydrogen, deuterium, helium, and lithium, which are exquisitely sensitive to the temperature of that radiation. Of course, we also need an explanation for the existence of the CMB in the first place, since the Big Bang evidently didn't happen in Bill's world.
Existence of metals. (Of course, I mean metals in the sense that astrophysicists use the term). I assume that supernovae don't happen in Bill's world, since a supernova occurring 4.5 ly away would preclude the existence of the earth. So, Bill—how did metals get here? I'm assuming since there was no big bang, they've always been here, but I'm hoping your answer is a little more entertaining than "I don't need to explain how metals got here, because they've always been here."
Cosmic redshift. Obviously, neither stars nor galaxies have a recession velocity, since they're all at the same distance from the earth (4.5 ly), and presumably always have been. So what accounts for the observed redshift? Tired light? Intervening dust? God playing tricks on us?
Distance to the celestial sphere. Bill, you say you know the distance to the A Centauri system. But how did you derive that distance? By its parallax? Even if, as WKV points out, parallax could be due to a wobbly cosmic sphere, you wouldn't be able to determine the sphere's distance that way. The reason we know the distance to A Centauri is because we know the diameter of the earth's orbit around the— oh, wait. The earth doesn't revolve around the sun. So what's the base of the triangle that allows us to compute the distance to the celestial sphere?
I'm sure I'll think of other phenomena in need of explanation, but I thought I'd give you a few to get you started.
And yes, I will expect an explanation for all of them, since there's already a perfectly good, non-geocentric, explanation for them. No one said re-writing the laws of nature was going to be easy, or quick.
