The Copernican concept of the Earth circling the Sun, rather than the Sun circling the Earth, was not entirely original with Copernicus. The Greek astronomer and mathematician Aristarchus of Samos was the first (that we know of!) to propose a Sun-centered system. Aristarchus' ideas were not widely accepted at that time, 2400 years ago, and the Earth-centered system of Aristotle became predominant. It fell to Copernicus and Galileo to make these ancient ideas more widely accepted.
Just for the record, Aristotle may have been the wrong-est person in human history. His false ideas about motion, medicine, science and astronomy were all entirely incorrect. It would not be too much of an exaggeration to state that if Aristotle had been a space alien whose mission on Earth were to keep humans ignorant and savage, he could not possibly have been more successful.
Ptolemy proposed a geocentric model, with Earth at the center and planets orbiting it. Copernicus suggested a heliocentric model, with the Sun at the center of the solar system. Galileo's telescopic observations supported the heliocentric model and provided evidence for Copernicus' theory.
Nicolaus Copernicus
Copernicus's concept of the solar system was influenced by the ancient Greek astronomer Aristarchus of Samos, who proposed a heliocentric model in which the Earth and other planets revolved around the Sun. Copernicus built upon this idea and formulated his own heliocentric model in the 16th century.
In a book called On the Revolutions of the Heavenly Bodies (that was published as Copernicus lay on his deathbed), Copernicus proposed that the Sun, not the Earth, was the center of the Solar System. Such a model is called a heliocentric system. The ordering of the planets known to Copernicus in this new system is illustrated in the following figure, which we recognize as the modern ordering of those planets.For this reason, a heliocentric system is the Solar System with the sun in the center, so there is not an "opposite".
Ptolemy thought that the Earth was the center of solar system and most people believed this theory. But Copernicus thought that the Sun was the center of solar system and most people didn't believed this theory. Who was right? Copernicus was right because later Galileo prove that if the Earth was at the center then he couldn't see the phases of Venus. Sentences for heliocentric. Galileo proved that the Copernicus's theory which was heliocentric was right.

Nicolaus Copernicus
Nicolaus Copernicus challenged the geocentric theory and presented the heliocentric theory. The heliocentric system placed the sun at the center of the universe.
Nicoli Copernicus.
From about 1510-1514 Copernicus developed his first general outline of his new heliocentric system.
Nicholas Copernicus
Copernicus was the first to propose the Heliocentric theory, the correct theory that the Sun, not the Earth, is the center of the solar system.
Ptolemy proposed a geocentric model, with Earth at the center and planets orbiting it. Copernicus suggested a heliocentric model, with the Sun at the center of the solar system. Galileo's telescopic observations supported the heliocentric model and provided evidence for Copernicus' theory.
He proposed a Heliocentric system- that Earth orbits the sun.
