 Fundamentum Astronomiae

"Fundamentum Astronomiae" refers to a notable work in the history of astronomy written by the Polish mathematician and astronomer Nicolaus Copernicus. Published in 1543, it is often recognized for delineating the heliocentric model of the solar system, where the sun is at the center and the planets, including Earth, revolve around it, contrary to the earlier geocentric model which placed the Earth at the center.
