Question

Does earth move in the ptolemaic system?

Answer 1

Answer:

In the Ptolemaic system each planet revolves uniformly along a circular path (epicycle)

Explanation:

In the Ptolemaic system each planet revolves uniformly along a circular path (epicycle), the center of which revolves around Earth along a larger circular path (deferent). By carefully coordinating these two cycles, the epicyclic model explained the observed phenomenon of planets retrograding when at perigee.The main idea of the Ptolemaic System was that the planet Earth was the center of the universe and all of the other planets, stars, and the Sun revolved, or circled, around it. Ptolemy used math to describe how the planets, Sun, and stars moved around the earth. Ptolemy thought that all celestial objects — including the planets, Sun, Moon, and stars — orbited Earth. Earth, in the center of the universe, did not move at all. NOTE: The outer planets, like Uranus and Neptune, are missing from both charts because they had not been discovered at the time. So it was false
