Coppernicus
Aristarchus, an ancient Greek astronomer, thought the sun was at the center. Centuries later Copernicus told his students that orbital trajectories were easier to calculate assuming the sun was the center. In 1610 Galileo observed Jupiter with a home made telescope, and his observations of it and Venus lead him to conclude the sun had to be the center of the solar system. Ten years before Galileo's observations, Giordano Bruno was burned at the stake for his heresy of a heliocentric solar system. But of these folks, Galileo's astronomy was the cleanest, best argued, and had the most supporting evidence.
