geocentric
Claudius Ptolemy synthesized and extended Hipparchus' system of epicycles and encentric circles to ezplain his geocentric theory off the solar system.
If I remember correctly claudius ptolemy and Tycho Brahe discovered geocentric.
Galileo, Copernicus, and Ptolemy were key figures in the history of astronomy, each contributing to our understanding of the universe. Ptolemy, in the 2nd century, proposed the geocentric model, placing Earth at the center of the universe, which dominated for centuries. In the 16th century, Copernicus challenged this view with his heliocentric model, suggesting that the sun is at the center, revolutionizing astronomical thought. Galileo, in the early 17th century, supported Copernicus's theory through his telescopic observations, ultimately facing opposition from the Church for advocating this shift away from the geocentric perspective.
Ptolemy developed the geocentric model of the universe, which positioned the Earth at the center and proposed that all celestial bodies, including the Sun, Moon, and planets, revolved around it in circular orbits. This model, detailed in his work "Almagest," dominated astronomical thought for over a millennium until the heliocentric model proposed by Copernicus gained acceptance. Ptolemy's system also included the concept of epicycles to explain the observed retrograde motion of planets.
Ptolemy has two craters, an asteroid and a system named after him.The crater Ptolemaeus on Mars.The crater Ptolemaeus on the Moon.The asteroid 4001 Ptolemaeus.The geocentric model of the universe, known as the Ptolemaic system.
ptolemy formulated the geocentric theory...
Claudius Ptolemy disproved geocentric theory.
The geocentric theory was developed by ancient Greek philosophers, primarily by Ptolemy in the 2nd century AD. This theory posited that the Earth was the center of the universe around which all other celestial bodies revolved.

The idea of elliptical orbits in the geocentric theory was introduced by the ancient Greek astronomer Claudius Ptolemy, who proposed a complex system of epicycles and deferents to explain the observed motion of celestial bodies.
