The dominant theory before Aristarchus and after him, until the time of Copernicus, was the geocentric paradigm promoted by the theories of Aristotle (384-322 BC) and Claudius Ptolemy (c. AD 90-168).
If you've read anything about scientific "paradigms" -- for example, in Thomas Kuhn's The Structure of Scientific Revolutions (1962) -- you know something about how fundamental paradigms are in providing the regulative ideals by which scientists conduct their work.
In fact, Kuhn shows that, contrary to the views about the foundations of science promoted by the father of Scientific Positivism, August Comte (1798-1857), science cannot prove its own presuppositions and depends on assumed paradigms, scientific progress has not consisted in a steady and incremental "growth in knowledge," but rather a haphazard movement that advances by fits and starts and even accidental discoveries of new paradigms.
I don't know about you, but I love to watch what happens when ideas and theories are proposed that rock the boat of prevailing orthodoxies. This is one reason I enjoy all the recent theories that question "Climate Science" or "Evolutionary Theory," for example. What I find particularly amusing (I know, it's my perverse and fallen sense of humor) is how exercised and upset the "true believers" and self-appointed guardians of prevailing dogmas and orthodoxies become over these unorthodox theories.
Appeal to authority is the weakest form of argument, just as ridicule is the last resort of bad arguments. And what is fascinating is how quickly "true believers" stoop to ridicule based on the prima facie "absurdity" of the "doubters" -- anyone who questions the authority of the prevailing wisdom of Climate Scientists (remember: Al Gore was awarded a Nobel Prize in 2007 for his promotion of "knowledge" about global warming), the Evolutionist theories of Richard Dawkins, et al., and the currently regnant cosmological paradigm of heleocentrism.
So, for anyone interested in something completely "unorthodox," something prima facie totally "absurd" and "ridiculous," but explicitly appealing to scientific "data" in ways that drive "true believers" insane, I present for your enjoyment the latest "doubters" of the heleocentric paradigm:
