Copernican heliocentrism

Copernican heliocentrism is the astronomical model proposed by Nicolaus Copernicus, which places the Sun at the center of the solar system, with Earth and other planets orbiting around it. This was a revolutionary shift from the earlier geocentric view, where Earth was considered the center. Copernicus’s model explained planetary motions more simply and accurately, highlighting Earth's rotation and orbit as reasons for the observed movements of planets. This heliocentric theory laid the groundwork for modern astronomy, emphasizing the Sun's central role and changing our understanding of our place in the universe.
