Copernican system the theory that the sun is the centre of the solar system, with the planets (including the earth) orbiting round it, formulated by the Polish astronomer Nicolaus Copernicus (1473–1543). He proposed a model of the solar system in which the planets orbited in perfect circles around the sun, and his work ultimately led to the overthrow of the established geocentric cosmology. He published his astronomical theories in De Revolutionibus Orbium Coelestium (1543).
