Whose model placed the Sun at the center?

The idea that the Sun, not the Earth, lies at the centre of the solar system was championed by the Polish astronomer Nicolaus Copernicus, who published his heliocentric model in 1543, the year of his death. For centuries, the prevailing view had been the geocentric model, in which the Earth sat motionless at the centre and everything revolved around it. Copernicus proposed instead that the planets, including Earth, orbit the Sun, and that Earth daily rotation explains the apparent movement of the sky. This revolutionary idea challenged both established science and religious teaching. It was later strengthened by the observations of Galileo, the precise measurements of Tycho Brahe, and the laws of Johannes Kepler, who showed the orbits were ellipses. The Copernican revolution transformed humanity understanding of its place in the cosmos.
