The Heliocentric theory.
It made significantly better predictions of planetary positions in our sky.
It offered more natural explanation for the apparent retrograde motion of planets in our sky.
Copernicus used perfect circles for the orbits of the planets.
A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center. A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)
that the world was heliocentric not geocentric aka sun centered universe and earth centered universe
The heliocentric model is sun-centered. The geocentric model is earth-centered.
a sun centered model

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.
The earth has seasons mainly because of the tilt to the earth towards or away from the sun. Contrary to popular belief, the distance from the sun caused by Earth's elliptical orbit only makes a minuscule difference in climate.
The Polish astronomer Nicolaus Copernicus.
It made significantly better predictions of planetary positions in our sky.
The Sun-centered or heliocentric model of the solar system is called the Copernican model (after Copernicus) and more closely matches the modern astronomical notions. By contrast, the geocentric or Earth-centric model is often called the Ptolemaic.
