In the Ptolemaic system, each planet is moved by a system of two spheres: one called its deferent, the other, its epicycle. The deferent is a circle whose center point, called the eccentric and marked in the diagram with an X, is removed from the Earth.
Introduction. 1  The basic elements of Ptolemaic astronomy, showing a planet on an epicycle (smaller dashed circle), a deferent (larger dashed circle), the eccentric (Ã) and an equant 2  (â¢). The complexity to be described by the geocentric model. 3  The basic simplicity of the Copernican universe, from Thomas Digges' book.
