Answer:
Nicolas Copernicus has first created his sun centered model of the universe named as Copernican heliocentrism. In this model Sun was at the center and the orbits of the planets around it were shown in the form of circular lines, which represents that the planets are orbiting around the sun in circular orbits with the uniform motion. Although Ptolemaic model considered earth at the center but he gave the accurate predictions regarding the planetary positions as in his model some orbits were represented by the epicycles which not only tells about the retrograde motion of the planets but also about the changes in their distances from the earth (earth is at the center in this model) with time.
