Answer: Heliocentric system
Explanation: The heliocentric model of the universe, according to Copernicus, the Copernican model, is a thesis that is still valid today, that the Sun is the center of the solar system and that the planets revolve around the sun. This was in contradiction with the geocentric system advocated by the Church, that the Earth was the center of the solar system. Also, according to Copernicus, the planets do not revolve around the Sun along the circular paths, but elliptical.
