Did Galileo Galilei view the solar system geocentric or heliocentric?

Answer 1

Galileo made important discoveries in dynamics but he contributed little to the debate about the geocentric and heliocentric theories. His quarrel with the church caused a polarisation that was seized on by the reformed protestant church which liked to claim that the catholics were opposed to the truth. But the heliocentric theory was not shown to be the right one until about 100 years after Galileo's time.

Answer 2

Galileo supported the Copernican system in which the Earth and other planet travel in orbits based on circles, that is circles with epicycles.

The Copernican system was simpler in one sense, because the epicycles that correct the circular main orbit are smaller. In the Ptolemaic system the main epicycle had to have approximately the same radius as what we now know as the Earth's orbit. On the other hand in Copernicus's system each planet had a basic circular orbit, and then a series of small epicycles to correct the known changes in distance from the Sun and the inclination to the ecliptic, as we now understand them.

The circles and epicycles were thrown out when Kepler came along with his discovery of elliptical orbits each one lying in its own plane close to the plane of the ecliptic. This is the theory that stood the test of time and is now generally accepted as right.

Answer 3

Heliocentric.

Answer 4

yes he did
