The main distinction of the modern model of the solar system from previous models is that the sun is at the center of the solar system. This is known as the heliocentric model, first proposed by Nicolaus Copernicus in the 16th century. In contrast, previous models, such as the Ptolemaic model, placed the Earth at the center of the solar system, known as the geocentric model. Additionally, the modern model of the solar system recognizes that the orbits of planets are elliptical rather than circular, which was another departure from previous models.
