The Ptolemaic Model followed a geocentric model of the solar system.
This was then challenged by Nicolaus Copernicus, who claimed a heliocentric model which sparked an integral part of the Scientific Revolution called, the Copernican Revolution.
Copernicus' proposal was followed by the Tychonic Model, with attempted to compromise with the geo- and heliocentric models.
Then, Kepler improved by suggesting elliptical orbits.
The Copernican Revolution came to a close with further speculation from Galileo Galilei and Isaac newton
TL;DR Because they were wrong
Both systems assumed circular orbits for the planets. Johannes Kepler's suggestion that the orbits were more eliptical solved this problem.
Galileo supported the Copernican system, but Aristotle did not. The Copernican system was a belief that the sun was the center of the solar system.
Galileo. With the help of the telescope that he invented, he was able to discover that Venus had phases, that Jupiter had moons, and that the Sun had spots, which would move across its periphery. Under Aristotle's/Ptolemy's models, these thing would not be able to occur.
what evidence did ptolemy have for the solar system
The name for the model of a solar system in which planets (and the Sun) revolve around the Earth is called geocentric. Modern astronomy rejects the idea, dating back to Copernicus who was a proponent of the notion that the planets orbited around the Sun (heliocentric). The heliocentric model is thus also called the Copernican, and the geocentric (with models presented most famously by Aristotle and Ptolemy) is called the Ptolemaic.
There are a number of factors that influenced Ptolemy. He was mainly influenced by the intellectual development of Hipparchus of Bithynia among other philosophical aspects of life.
