Question

astronomer Nicolaus

Answer 1

Nicolaus Copernicus (1473-1543) was an astronomer from Poland who is best known for his theory of heliocentrism, which states that the Earth revolves around the Sun. This idea was a significant departure from the ancient belief that the Earth was the center of the universe. Copernicus's work laid the foundation for the Scientific Revolution and had a profound impact on the field of astronomy. His major work, "De Revolutionibus Orbium Coelestium" (On the Revolutions of the Heavenly Spheres), was published shortly before his death.
