Copernican heliocentrism. Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. It positioned the Sun near the center of the Universe, motionless, with Earth and the other planets rotating around it in circular paths modified by epicycles and at uniform speeds.
From Wikipedia, the free encyclopedia. Nicolaus Copernicus (February 19, 1473 â May 24, 1543) was the astronomer who provided the first modern formulation of a heliocentric (sun-centered) theory of the solar system, in his epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres).
