Aristotle
Nicolaus Copernicus was the astronomer to challenge the geocentric model of the solar system.
In a geocentric solar system model, earth is in the center, and all of the planets and then sun orbit around it. Geo= Earth Centric= Center
This would be known as a geocentric model, and it is pretty easy to show why such a model is unlikely.
A geocentric model of the solar system. Which is incorrect.
The geocentric. The two systems were the geocentric and heliocentric, the former with the earth at the solar system's center, and the latter with the sun. Because Copernicus championed the latter, it is often called the Copernican model.
Claudius Ptolemy
A Geocentric model places Earth at the center of the Universe, with all of the stars and planets revolving around it. The most famous such model is that of Ptolemy. It stood as the accepted model until Copernicus was proven right by Galileo and Kepler.
Nicolaus Copernicus was the astronomer to challenge the 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.
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
Geocentric model. This has earth at the centre. We now know this not to be true.
In a geocentric solar system model, earth is in the center, and all of the planets and then sun orbit around it. Geo= Earth Centric= Center
This would be known as a geocentric model, and it is pretty easy to show why such a model is unlikely.
It is the geocentric model.
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.
There is no geocentric model of the earth!
One of them was Claudius Ptolemy. He made a geocentric model and called it Plotemy's system, it lasted 13 centuries.
