The person who developed the first comprehensive model for a heliocentric cosmology was Copernicus. He proposed that the Sun was the center of the universe, and that the planets revolved around it in circular orbits. This was a major departure from the prevailing geocentric model, which held that the Earth was at the center of the universe. Kepler and Ptolemy also made important contributions to astronomy, but they did not develop a comprehensive heliocentric model. Aristarchus proposed a heliocentric model in ancient Greece, but his ideas were not widely accepted at the time.
