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.
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.
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.
Galileo supported Copernicus's heliocentric theory
Galileo accepted the heliocentric view fully.
Isaac newton supported the heliocentric system as manifested in his derivation of Keplars laws.
The heliocentric system
Yes
geocentric
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
The heliocentric model is sun-centered. The geocentric model is earth-centered.
In a geocentric universe the earth is the center of the universe or solar system and everything revolves around it. In a heliocentric universe the sun or a star is the center of the universe or solar system. We live in a heliocentric solar system with the sun as the center.
As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
Neither the earth nor the sun is the centre of anything unless you are looking at a very narrow perspective. The sun is in the outer part of one of several arms of the milky way galaxy. That is one of several galaxies in our local cluster, and so on. So, in astronomical terms, neither system is correct.The heliocentric system is better when studying the solar system but that is about as far as the comparison can go.
The proposed the heliocentric system.
Geocentric: Earth is center of the solar system. Heliocentric: Sun is the centre of the solar system.
The Heliocentric System. m.i.
Uranus is in the heliocentric system like all the other planets. The geocentric system is now only of interest historically. It wasn't correct.
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
the heliocentric system and the geocentric system
Heliocentric = The Sun is at the center of our solar system. Geocentric = The Earth is at the center of our solar system. Insisting the Sun is at the center, which it is, once very much angered the church.
The phases of Venus are well supported by the heliocentric system, but they are also supported very well by the previous geocentric system. All you need for Venus to have phases is that Venus should pass between Earth and Sun. That happens in both the heliocentric system and the geocentric system.

Geocentric understanding places the Earth at the center of the solar system or universe (depending on what is being discussed, and when) A Heliocentric understanding places the sun at the center of the solar system, or universe.
The planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.
