Nicolaus Copernicus (February 19, 1473 – May 24, 1543) was the first European astronomer to formulate a modern heliocentric theory of the solar system. His epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), is often conceived as the starting point of modern astronomy, as well as a central and defining epiphany in all the history of science.
