Nicolaus Copernicus (1473–1543) was a Renaissance astronomer and mathematician who is best known for formulating the heliocentric model of the universe, which posited that the Earth and other planets revolve around the Sun. This was a significant departure from the geocentric model that had dominated Western astronomy, which placed the Earth at the center of the universe.
