∙ 12y agoearly Greeks (600bc - ad150) established a geocentric model that placed the earth in the middle of the revolving solar system. it was popular because human instinct believes so highly of itself, why would you place our rock in anyother than the center if there was no proof otherwise? it was later that aristarchus was to create a heliocentric model where the sun was in the center of the universe, but because lack of popularity the geocentric model remained most believed up until a few hundred years ago with the invention of the telescope by Galileo galilei. which was about the time church and science was confronted with a problem and Galileo was arrested for 10 years until his death for trying to publish his discovery relating heliocentric model. people can be ignorant sometimes what you know, it just ain't so.
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.
Heliocentric was thought to believe that the sun was at the center of the solar system and that the planets revolved around the Sun. Geocentric was thought to believe that the earth was the center of the solar system and that the planets revolved around the earth. We now know that our solar system is centered around the sun and is heliocentric.
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.
The geocentric model shows earth as the center of the universe. That means everything even the sun revolves around it. That was the theory used in early Greek astronomy. Heliocentric literally means, "sun in the center." That is the way our solar system really is, with everything revolving around the sun. It has been proven by space probes and missions
The heliocentric 'theory' is not really a theory at all, more an assertion that the Sun is at the centre of the solar system. Copernicus's theory assumes that the Sun is at the centre and provides a model of the planets' orbits that uses circles and epicycles to explain the observed orbits. He said it was simpler than the old "geocentric" (Earth centred) Ptolemaic system, but it was not really, it actually had more epicycles. Note: Perhaps the questioner got mixed up. The Copernican theory IS a heliocentric theory. Perhaps the question is about the geocentric theory and the Copernican theory. Anyway, Kepler simplified the heliocentric theory and now we know that his model is correct.
Geocentric: Earth is center of the solar system. Heliocentric: Sun is the centre of the solar system.
The main difference - is the centre of the galaxy. The heliocentric theory placed the Sun at the centre of our galaxy - the previous 'geocentric' theory placed the Earth at the centre.
Heliocentric is the motion of earth around the sun. Geocentric is the motion of earth rotating about its axis.
The geocentric universe was proposed by Ptolemy and focuses the Earth in the center of the universe. The heliocentric universe was proposed by Nicolas Copernicus and focuses the Sun as the center of the universe. However, both have been proved wrong.
Geocentric is that the earth is the center of the universe and heliocentric is the sun is the center of the universe. can it be nothing.
The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets

Geo means Earth and helio means Sun. Geocentric means Earth centered, and heliocentric means Sun centered. The Earth and planets revolve around the Sun.

One would be that they both have a massive object in the center.
