was born on February 19, 1473 in Torun,
In 1503, he moved to Frauenburg where he made his first astronomical observations. He became more dissatisfied with Earth-centered theories and developed one of his own, by which Earth spun on its own axis and it along with the other planets revolve around a center point in space near the Sun. After developing this theory, Copernicus created and circulated a manuscript summary of his observations titled, Commentariolus. “Not until 1540, did he consent to the publication of his complete work, On The Revolutions of the Celestial Spheres.” (The Encyclopedia Britannica, 15th Edition, p. 610)
Copernicus’s findings had a profound impact on the study of astronomy and philosophy for the following centuries.
