"it took another 200 years to detect parallax"
However, the aberration of starlight was detected in the early 1700s. Although no one had thought to predict its appearance, people quickly realized it only made sense if the Earth was in motion, and was impossible to produce in a geocentric model.
(And, of course, heliocentric elliptical orbits of Kepler explained planetary motion much better than any geocentric system.)
