E. all of the above. It was propagated by a series of astronomers such as Copernicus, Kepler and Galileo. Since the Sun was the center of the universe, it did not move, nor did the stars. The planets with smaller orbits, or closer to the Sun, move Copernicus stated his heliocentric model that could explain the apparent changes in the motion of the planets and the "Copernican Revolution" began. Copernican heliocentrism is the name given to the astronomical mannequin developed by Nicolaus Copernicus and printed in 1543. *explains retrograde motion by planets passing each other.

Nicholas Copernicus, Aristarchus, Tycho Brahe and Johannes Kepler, Galileo Galilei, Sir Issac Newton. The Heliocentric Model • Could predict positions of planets in the sky –BUT only as well as Ptolemy’s model • Could account for the order of the planets and retrograde motion but could not accurately determine the orbit distances from the Sun. The astronomer given the credit for presenting the first version of our modern view of the Solar System is Nicolaus Copernicus, who was an advocate for the heliocentric, or Sun-centered model of the solar system. The heliocentric theory argues that the Sun is the central body of the solar system and perhaps of the universe.Everything else (planets and their satellites, asteroids, comets, etc.) C. included elliptical orbits.

The heliocentric model was generally rejected by the ancient philosophers for three main reasons: If the Earth is rotating about its axis, and orbiting around the Sun, then the Earth must be in motion.Since no stellar parallax is observable (at least, with the naked eye), the Earth must be stationary. The Heliocentric System. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center. As early as the 4th century BC, a philosopher named Philolaus was one of the first to suggest that the Earth moved around the sun instead of the sun orbiting around the Earth. D.

The analogous models can be found in history, as the geocentric and heliocentric models characterized the astronomical development in Europe. The geocentric model was eventually replaced by the heliocentric model. The Heliocentric Universe revolves around it. D. made very accurate predictions for the positions of the planets. The epicycles were just an illusion caused by our own orbit around the sun. Models of the universe. It positioned the sun near the center of the universe, immobile, with Earth and the opposite planets rotating round it in round paths, modified by epicycles and at uniform speeds. Also, the heliocentric model of the universe had proponents in the medieval Islamic world, lots of whom would go on to encourage Copernicus. This model positioned the Sun near the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds. Heliocentric means the solar system is sun centered. Ptolemy's model envisioned each planet moving in a small circle, the center of which moved along a large circular orbit about the earth. Pyrocentric. This appeared is distinct from the idea of geocentrism, that the erath is at the center of the universe (or our solar system).
