The geocentric model is a Earth-centered model in which everything orbits around Earth. However, unlike the geocentric model, the heliocentric model is a sun-centered model in which everything orbits around the sun.
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.)
That would be Tycho Brahe who created the heliogeocentric model of the universe, which never became prominent at all.
That would be the moon. We've never thought of it that way ... the only object whose status didn't change between the geocentric and heliocentric model. Thanks for showing it to us.
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
Heliocentric is the motion of earth around the sun. Geocentric is the motion of earth rotating about its axis.
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.
The heliocentric model places the sun at the center of the solar system where the gercentric model places the Earth at the center.
Geocentric models had the earth as the center of the universe with the sun and all the planets orbiting it. Heliocentric models (the current accepted ones) have the sun as the center, with the earth and planets orbiting it.

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.
Geocentric- the Earth is at the center of all things with the sun, moon, planets, and stars all orbiting around it. If this were true, all of the planets would be going in little loops around us. Heliocentric- The Sun in the center of the solar system.
You should read a book and find out, don't always go the easy way out. Timmy Same- Both are models of the solar system and how the sun and planets are arranged. Different- Geocentric- revolves around the earth. Heliocentric- Planets (including Earth) revolve around the sun. your welcome.
The Moon.
The planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.
