Question

Quizplus · Accepted Answer

Johannes Kepler proposed a heliocentric (Sun-centered) model of the solar system in which the planets move in elliptical orbits, not circular ones. This was a significant advancement over previous models, including the Ptolemaic system, which was geocentric (Earth-centered), and the Copernican system, which was also heliocentric but assumed circular orbits.
