Which historical figure is associated with the geocentric model of the solar system?

The geocentric model of the solar system is most famously associated with Ptolemy, an ancient Greek astronomer and mathematician who lived during the 2nd century AD. In his work, particularly the "Almagest," Ptolemy presented a detailed explanation of how the Earth is at the center of the universe, with the Sun, Moon, planets, and stars revolving around it. This model was widely accepted for many centuries and was foundational in shaping the early understanding of celestial mechanics.

Ptolemy's geocentric system was built on the belief that the Earth was stationary, which was a view deeply rooted in the philosophical and cosmological ideas of the time. His theories were later expanded and refined but fundamentally remained geocentric. The eventual shift to a heliocentric model by figures like Copernicus challenged this long-standing perspective and laid the groundwork for modern astronomy.
