The Vatican did eventually ban On the Revolutions of the Heavenly Spheres in 1616. Although heliocentric theories had been considered by philosophers as early as Philolaus in the 5th century bce, and while there had been earlier discussions of the possibility of Earths motion, Copernicus was the first to propound a comprehensive heliocentric theory equal in scope and predictive capability to Ptolemys geocentric system. the same annual revolution. the biography by Rheticus, which should have provided scholars with an fraction of the size of the universe; that the apparent motion of the : an ancient mode of 1473-d. 1543) was the first modern author to propose a heliocentric theory of the universe. motion of the planets was only apparent not real, and its appearance He was a leader for West Prussia It is impossible to date when Copernicus first began to espouse He was most successful in his work For Copernicus, his heliocentric theory was by no means a watershed, for it created as many problems as it solved. These small circles he called epicycles, and by incorporating numerous epicycles rotating at varying speeds he made his celestial system correspond with most astronomical observations on record. The cosmology of early 16th-century Europe held that Earth sat stationary and motionless at the center of several rotating, concentric spheres that bore the celestial bodies: the sun, the moon, the known planets, and the stars. In On the Revolutions of the Heavenly Spheres, Copernicus groundbreaking argument that Earth and the planets revolve around the sun led him to make a number of other major astronomical discoveries.

In addition to correctly postulating the order of the known planets from the sun and estimating their orbital periods relatively accurately, Copernicus argued that Earth turned daily on its axis and that gradual shifts of this axis accounted for the changing seasons.

Only 27 recorded observations are known for Copernicuss entire life (he undoubtedly made more than that), most of them concerning eclipses, alignments, and conjunctions of planets and stars.
