Heliocentric - Sun-centred
Geocentric - Earth-centred
The ancient view was that the Earth is fixed at the centre of the Universe and everything else revolves around it. That is the geocentric view and astronomers still use geocentroc coordinates to describe the positions of objects in the night sky, because these are the numbers that are needed to set up a telescope.
Starting with Copernicus in 1543 the heliocentric idea that the Earth revolves round the Sun began to gain currency, and in 1609 Kepler produced a new innovative model that had the Sun at the centre and the planets in elliptical orbits.
In 1687 with the publication of Newton's laws of motion and the laws of gravity Kepler's model was shown to be based on good theoretical principles, with the planets' elliptical orbits resulting from the Sun's gravitational force.
With the exception of minuscule adjustments due to Einstein's General Theory of Relativity, Kepler's model is still the one that is used today.
What else can I help you with?
How do the geocentric and heliocentric models of the solar system compare?
Models are designed to serve particular purposes. In the case of astronomical models, they are designed to explain how things in the sky behave. For this purpose, heliocentric models are superior, because they are a closer description of what actually happens than geocentric models. They aren't ENTIRELY accurate, but close enough. However, if your purpose is to navigate on the surface of the Earth using a sextant, geocentric models are almost as accurate and make it a WHOLE lot easier to do the math. (I used to be an instructor in the US Air Force's celestial navigation school.)
What is the main difference between geocentric and helicentric models of the solar system?
Geocentric model that was prevalent in the middle ages said that the Earth was in the center of the solar system (in fact of the universe) and all other planets revolved around it. Modern science says that in the solar system the Sun is at the center and all its planets revolve around it.
Which astronomer proposed a universe that combined the heliocentric and geocentric models?
Tycho Brahe proposed a universe where the Earth was at the center (geocentric model) while other planets revolved around the Sun (heliocentric model). His system was known as the Tychonic system, which attempted to reconcile both models.
What is the opposite of the geocentric system?
helliocentric - where the sun is the center of the universe.
What object is at the center of a geometric system?
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.
What is the main different between the geocentric and heliocentric models of planetary motion?
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
Why is Uranus and Neptune not included in the heliocentric and geocentric model of the solar system?
The planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.

Who contradicted the geocentric system?
The Heliocentric System. m.i.
Was Copernican in the heliocentric or geocentric system?
The proposed the heliocentric system.
What is the difference between the geocentric view and the heliocentric view?
Geocentric: Earth is center of the solar system. Heliocentric: Sun is the centre of the solar system.
Is Uranus in the heliocentric or the geocentric system?
Uranus is in the heliocentric system like all the other planets. The geocentric system is now only of interest historically. It wasn't correct.
What object is in the center of a geocentric system?
earth
What is the opposite of the geocentric system?
helliocentric - where the sun is the center of the universe.
What is a description of the solar system in which all planets revolve around Earth?
Geocentric model. This has earth at the centre. We now know this not to be true.
