his model of the universe.
Nicholas Copernicus
Earth was the center of the universe
Copernicus and Galileo
Stellar parallax could not be observed until hundreds of years after Copernicus: the effect is very small. Rejection of the Copernican system was not irrational.

Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the moon.No. The above answer is incorrect.Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the EARTH in epicycles. Not the moon. (The model that modeled the planets orbiting earth was the Geocentric model. Aristotle theorized this.)Copernicus's model is known as the Heliocentric model. Ptolemy's theory of epicycles is when the planets revolved in large circles around Earth.

Ptolemy put the Earth at the center of his model of the universe , and said that the Sun , the moons , the planets ,the asteroids , comets , and meteors orbit the Earth and the Earth was the center of the universe.
