  Geocentric model - Wikipedia, the free encyclopedia
The geocentric model assumes a spherical Earth; thus it is not the same as the older flat Earth model.
The geocentric model held sway into the early modern age; from the late 16th century onward it was gradually replaced by the heliocentric model of Copernicus, Galileo and Kepler due to the simplicity and predictive accuracy of that newer model.
The relation of the two pictures [geocentricity and heliocentricity] is reduced to a mere coordinate transformation and it is the main tenet of the Einstein theory that any two ways of looking at the world which are related to each other by a coordinate transformation are entirely equivalent from a physical point of view...

The geocentric model assumes a spherical Earth; thus it is not the same as the older (Click link for more info and facts about flat Earth) flat Earth model.
This view of a geocentric universe held sway for well over a millennium, but was seriously challenged by the publication of (A conspicuous crater on the moon) Copernicus's De Revolutionibus Orbium Coelestium in 1543, which posited that the Earth and the other planets instead revolved around the Sun.
The geocentric (Ptolemaic) model of the solar system is also of interest to (An apparatus or model for representing the solar systems) planetarium makers, as for technical reasons a Ptolemaic-type motion for the planet light apparatus has some advantages over a Copernican-type motion.

 Encyclopedia: Geocentric model
A small number of people still advance a geocentric model (see the article on modern geocentrism, which also discusses the modern scientific point of view in detail).
Modern Geocentrism is the advocation of a geocentric (Earth-centered) model of the universe.
Obsolete scientific theories Sir Fred Hoyle (June 24, 1915 – August 20, 2001) was a British astronomer, notable for a number of his theories that run counter to current astronomical opinion, and a writer of science fiction, including a number of books co-authored by his son Geoffrey Hoyle.

At this time, geocentrism is rejected in scientific and popular opinion; and it is believed that the Sun is at the centre of the solar system, but not the universe (see Heliocentrism).
A small number of people still advance a geocentric model (see modern geocentrism).
These people tend to be of a religious mindset and sometimes Creationists, because without the concept of God willing to create the Earth at the center of the universe, it would appear mysterious for it to be so.

 Solar System Models   (Site not responding. Last check: 2007-09-17)
Ptolemy (200 A.D.) was an ancient astronomer, geographer, and mathematician who took the geocentric theory of the solar system and gave it a mathematical foundation (called the "Ptolemaic system").
In the first book of the Almagest, Ptolemy describes his geocentric system and gives various arguments to prove that, in its position at the center of the universe, the Earth must be immovable.
Unfortunately, the geocentric model was accepted as doctrine and, therefore, was not subjected to the scientific method for hundreds of years.

 geocentric
This is the kind of parallax that is generally understood when the term is used without qualification.
{Horizontal parallax}, the geocentric parallx of a heavenly body when in the horizon, or the angle subtended at the body by the earth's radius.
{Geocentric latitude} (of place) the angle included between the radius of the earth through the place and the plane of the equator, in distinction from geographic latitude.

 Geocentric Datum Shift
A geocentric datum is a reference system that has as its origin the Earth’s centre of mass, and is the best fitting reference surface for the whole earth.
The adoption of a geocentric datum allows for a single standard for the collection, storage and use of geographic data, ensuring compatibility across various geographic information systems at the local, national and global level.
The current Australian Geocentric datum (AGD 84) is based on a mathematical surface of the Earth designed to fit the local Australian region.

 Geocentric (Ptolemaic) Perspective - Retrograde Epicyclic Motion - Scientific Revolution - Professor Robert A. Hatch
Here the earth is depicted in the center of a planetary orbit, for example Mars.
Because the earth is assumed to be fixed and stable in the center of the cosmos (geocentric and geostatic), and further, all heavenly bodies are assumed to move around the central earth, some device was needed to describe the apparent retrograde loop that planets make when in opposition to the sun.
In sum, from a geocentric perspective, retrograde motion was one of the major astronomical problems requiring attention in order to 'save the appearances.' To this end, Ptolemy's model was unsurpassed for simplicity, accuracy, and elegance until Copernicus some 1400 years later.

 Science and the Bible
Among the Semitic ancients, the notion of a geocentric universe was common.
Certainly, the ancient Semites had no use for such theories, and consequently the Bible reflects a geocentric universe and a flat earth.

 Converting from Geographic to Geocentric Coordinates   (Site not responding. Last check: 2007-09-17)
In a geocentric coordinate system, the latitude is measured at the center of the Earth and up (or down) from the equator.
But sometimes you might want to know the geocentric latitude instead, and in that case you will want to know how to convert from one kind of latitude to the other.
Longitude is not affected by converting from geodedic coordinates to geocentric coordinates.

Geocentric observers felt the sky moved around the Earth.
Since it does not appear the Earth is spinning, the only other option is that the sky must move.

 SCIENTIFIC EXPLANATION OF GEOCENTRICITY
Thus, there is evidence that the earth is NOT moving around the sun, but either the aether is moving around the earth carrying the planets with it, or the earth is spinning on its axis.
Bowden also notes that to hold a geocentric position is to open oneself up to abuse even from creationists who will think that you are discrediting the whole argument.
The other thing that he discusses which is fascinating is the idea that the speed of light may not be a constant, but may have slowed down over the last 6000 years or so since creation which would explain a lot of the facts that scientists throw our way.

In attempting to make sense of the earth’s motion, particularly its position in the space (regardless the significance of the term at the time), people have spent uncalculated amount of efforts to make observations throughout the history.
The gradual emerging from Ptolemy’s geocentric theory (100—170), to Tycho’s circular geocentric orbits (1546-1601) to Copernicus heliocentric model (1473—1543) signified such changes.
