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.
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.
Heliocentric.
yes he did

Geocentric model -- In a geocentric system Earth is at the center of the revolving planets. It is made by a Greek astronomer named Ptolemy. Heliocentric model -- In a heliocentric system Earth and the other planets revolve around the sun. It is made by Galileo.
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 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.

Galileo Galilei
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
The proposed the heliocentric system.
Geocentric model -- In a geocentric system Earth is at the center of the revolving planets. It is made by a Greek astronomer named Ptolemy. Heliocentric model -- In a heliocentric system Earth and the other planets revolve around the sun. It is made by Galileo.
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.
Galileo Galilei discovered phases in Venus -- pretty much proof of a heliocentric solar system -- in 1610 September.
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
As proposed by the Heliocentric Theory, the Sun is the center of 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
