Question

who came up with the geocentric model of the solar system

Answer 1

The geocentric model of the solar system, which posits that the Earth is the center of the universe and that all celestial bodies revolve around it, is most commonly associated with the ancient Greek philosopher Claudius Ptolemy. Ptolemy's model, detailed in his work "Almagest" in the 2nd century AD, synthesized earlier ideas by astronomers such as Aristotle and Hipparchus. The geocentric view dominated Western astronomical thought for many centuries until the heliocentric model, proposed by Nicolaus Copernicus in the 16th century, gained acceptance.
