developed the first heliocentric model of the soloar system
Nicolaus Copernicus
Ptolemy contributed to science and astronomy by developing the theory of the Earth. He was the first person to view the solar system as a heliocentric system instead of a geocentric system.
The heliocentric, or Sun-centered, system was first theorized by Nicolaus Copernicus.
A heliocentric model is a model of the planets' movements that places the Sun at the centre of the Solar System. Copernicus's model published in 1543 was the first heliocentric model. It resembled the Ptolemaic model in respect of the circles and epicycles that were used to explain the planets' movements. Kepler's model published in 1609 was also heliocentric, but it used planar elliptical orbits for the planets, which follow Kepler's 3 laws of planetary motion. It is now the accepted model.
The first person to theorize a heliocentric solar system was Aristarchus, a greek philosopher. However, he was ridiculed, and the first person to have the idea accepted was Copernicus.
He was the first astronomer to formulate a scientifically-based heliocentric cosmology that displaced the Earth from the center of the universe.

Nicolaus Copernicus
The heliocentric theory was first published by Copernicus.
The idea that Earth revolves around the Sunwas first realized in the 3rd_century_BCby Aristarchus_of_Samos. However, it was not until the 16th century that a fully predictive mathematical model of a heliocentric system was presented, by mathematician and astronomer Nicolaus_Copernicus. In the following century it was expanded by Johannes_Keplerand Galileo_Galilei.
Galileo
Rejected by his contemporaries and ignored for 18 centuries, Aristarchus of Samos proposed the first serious model of a heliocentric solar system. You may read about it in Archimedes' book, "The Sand Reckoner".

Aristarchus, in the 3rd century BC, was the first to postulate that our Solar System is heliocentric. Later, in 1743, Copernicus advanced the same hypothesis, but in a more comprehensive form.
It was the model devised by Copernicus.
From about 1510-1514 Copernicus developed his first general outline of his new heliocentric system.
