Ptolemaic Planetary System Model Astronomy Models Ptolemaic system, mathematical model of the universe formulated by the alexandrian astronomer and mathematician ptolemy about 150 ce. the ptolemaic system is a geocentric cosmology that assumes earth is stationary and at the centre of the universe. Geocentrism is a superseded astronomical model description of the universe with earth at the center. it is also known as the geocentric model, often exemplified specifically by the ptolemaic system. under most geocentric models, the sun, the moon, stars, and planets all orbit earth.
The Ptolemaic Planetary Model Robert Hatch Ptolemy combined all three constructions in the models of the planets, sun, and moon. a typical construction might thus be as in the picture below, where e is the earth, c the geometric center of the eccentric circle, q the equant point, f the center of the epicycle, and p the planet. Mercury and venus are never seen far from the sun so they have a special status in ptolemy's model. their epicycle centers must lie on the line connecting the earth and sun. the greeks had used geometry to estimate the distance to the stars as at least a million miles. Ptolemy made two great advances on hipparchus, on was the deferent epicycle model for the planetary motion, and the other was the equant model for main (deferent) cycle of the planets. The geocentric model, also known as the ptolemaic system, is the astronomical concept that places earth at the center of the universe, with the sun, moon, planets, and stars revolving around it in circular orbits.

In this article, we aim at presenting a thorough and comprehensive explanation of the mathematical and theoretical relation between all the aspects of ptolemaic planetary models and their counterparts which are built according to kepler’s first two laws (with optimized parameters). This model was developed by the ancient greek astronomer claudius ptolemy in the 2nd century ad. according to this model, the earth is stationary and all celestial bodies, including the sun, moon, planets, and stars, revolve around it in perfect circular orbits. Ptolemy developed a mathematical model that accounts for the movements of heavenly bodies, where the sun orbits in a circular motion, while planets describe complex paths combining two circular motions. Abstract in this article, we aim at presenting a thorough and comprehensive explanation of the mathematical and theoretical relation between all the aspects of ptolemaic planetary models and their counterparts which are built according to kepler's first two laws (with optimized parameters).
