Ptolemy's view of the universe placed the sun, the other solar system planets, and the stars inside a huge rotating sphere centered a point in space close to the earth.
Claudius Ptolemy, an ancient Greek astronomer and mathematician. His work, the Almagest, described a geocentric model of the universe where Earth was believed to be at the center of the cosmos with all other celestial bodies orbiting around it. This model was widely accepted until the heliocentric model proposed by Copernicus in the 16th century.
In Ptolemy's geocentric model, the deferent was a large circle centered on the Earth that carried the center of a smaller circle called the epicycle, where the planets moved. The equant was a point near the center of the deferent where the planet's motion appeared uniform. By incorporating these features, Ptolemy could account for the irregularities in the motion of the planets as observed from Earth, while still preserving the idea of circular orbits as proposed by Aristotle.
The idea that the Earth was the center of the universe was adopted because of the writings of Ptolemy and Aristotle. This was a common belief until the 1700s.
