EUDOXUS OF CNIDUS
This model places the planet Earth at the center of the universe, according to this model the earth would be motionless while the planets and other celestial bodies rotate around it in uniform circular motions.

CLAUDIUS PTOLEMY
Ptolemy was an astronomer from Alexander of Egypt and the author of an important astronomical treatise called Almagest. For Ptolemy, all planets and stars revolve around the Earth, often with bizarre and irregular orbits, and to explain this phenomenon Ptolemy used epicycles and circular orbits whose centers revolved around the earth.

NICHOLAS COPERNICUS
He Develops the thoughts of Aristarchus of Samo who first formulated the heliocentric theory, which states that the sun is located at the center of the cosmos and the planets and other celestial bodies revolve around it. However, the church rejected his ideas, and the heliocentric model was considered heretical until 1822.

Tycho brahe
Tycho Brahe was a Danish astronomer and astrologer. After several studies, he made a model of the solar system where the earth remains at the center of the universe, the sun rotates around it, and the other planets orbit the sun. Tycho also made a lot of observations and cataloged many stars.
Back to the timeline
JOHANN KEPLER
Kepler was a pupil of Brahe and expanded and modified many of his theses. Kepler was a follower of the Copernican model and realized that the orbits of the planets could be elliptical rather than circular. He also developed his laws of planetary motion based on Brahe's observations.
Back to the timeline
GALILEO GALILEI
The heliocentric model developed mainly thanks to Galileo, who in 1632 published the Dialogue Concerning the Two Chief World Systems, which was considered heretical by the Church and forced Galileo to deny his thesis. However, Galileo's discoveries remain a key element in the development of the heliocentric theory.
Back to the timeline
ISAAC NEWTON
Isaac Newton was born in the same year that Galileo died. He elaborated on the 3 laws of motion and the law of universal gravitation, which he linked to Kepler's laws of planet motion. As a result, the heliocentric model was accepted by the scientific community.
