No, Nicolaus Copernicus did not write Harry Potter. Harry Potter was written by J.K. Rowling, a British author, and it is a series of fantasy novels about a young wizard's adventures. Nicolaus Copernicus was a Renaissance-era astronomer known for developing the heliocentric model of the universe.
Nicolaus Copernicus was a Renaissance astronomer and the first person to formulate a comprehensive heliocentric cosmology, which displaced the Earth from the center of the universe. Copernicus dedicated the book to Paul III who was known for his astrological predilection. De Revolutionibus was a book and when he published it the gov't didn't want to get rid of the Earth-Centered (Geocentric) Theory so before they published De Revolutionibus, they wrote in the beginning of the book that the stuff written in the book was all fictional. The book was published in March 1543.
Nicolaus Copernicus was the promoter of the heliocentric theory, which states that the Earth and other planets revolve around the Sun. He published his theory in his book "De revolutionibus orbium coelestium" in 1543.
From Wikipedia: "De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) is the seminal work on the heliocentric theory of the Renaissance astronomer Nicolaus Copernicus (1473-1543)."
False, TrueThe original spelling and grammar of your question is so poor that the answer could be either.Nicolaus Copernicus (his name should be capitalized) did formulate a heliocentric cosmology. He was not "the pearson" (sic!) but "a person". He was not the first either, many Greek philosophers prior to 200 BCE also held heliocentric beliefs.We can assume that Copernicus spoke with others about his ideas, we do know that the book stating these ideas was published just shortly before Copernicus died.
