Was Isaac Newton's findings about the Solar System geocentric or heliocentric?

Answer 1

Ptolemy's research in the field of astronomy led him to continue down the vein of other Greek scholars who believed in the Geocentric system of planetary orbit. The Ptolemaic system, which believed that the planets and sun moved in small mini-orbits, known as epicycles, within a larger, greater orbit around the earth, was comprised in order from closest to farthest as Mercury, Venus, Sun, Mars, Jupiter, and Saturn. Due to this system's ability to fairly accurately predict the paths of the observable planets in the sky, it remained widely accepted until Copernicus became champion, if you will, of the Heliocentric theory. Even then, Ptolemy's system was still better able to explain the motions of the planets. It was not until the later addition of Kepler's laws of motion that the Heliocentric theory fell neatly into place.

Answer 2

Tycho supported the geocentric system, usually called the Ptolemaic system, at first, and then devised a system of his own, still geocentric with the Earth at the centre, but with Mercury and Venus in orbit round the Sun. The other planets and the Sun were as before, in orbit round the Earth.

Kepler then did detailed mathematical work, based on Tycho's observations but using a heliocentric system, and he came up with the idea of elliptical orbits for the planets. He found that elliptical orbits fitted the observations more accurately than previous models.

Newton's later theoretical discoveries of gravity and the laws of motion confirmed Kepler's model, and it became generally accepted. The older models that used combinations of circles were consigned to the history books.

Answer 3

Copernicus's theory was heliocentric and he put it forward as an alternative to Ptolemy's geocentric theory.

It was not possible to decide conclusively which was right until the discovery of the laws of motion and the law of gravity in the late 1600s, and then Kepler's theory, which is also heliocentric, became generally accepted.

Before then all three theories could predict the planets' positions quite accurately, with Kepler's theory the most accurate, and it was eventually found that Kepler's theory also fitted the new

scientific laws. We use Kepler's theory now.
