I'm not sure what you mean by asking this question, butI just wanted to 
comment on your statement about astronomerss discarding the sun-centered 
model. 
	On the subject of celestial mapping, it is much simpler to 
continue to think of a geocentric universe. After all, the earth happens 
to be where all the observers are (Voyagers notwithstanding), so why not 
continue to treat the earth as the center when it comes just to the basic 
task of finding out where other objects of interest may be?
	In a more physical context, no astronomer I know treats even the 
sun as the center of the universe - in fact, modern cosmology 
acknowledges no place in the visible universe as the center. So the 
issue of whether astronmers are reconsidering replacing the center of the 
universe with the earth may simply be a misunderstanding of the 
application  geocentrism to the mudane topic of mapping.

	just my 2 yen.
