Peuerbach is best-known for his work Theoricae Novae Planetarum, written in 1454, and published by his disciple Regiomontanus in 1472."The Early Manuscripts of Georg von Peuerbach's Theoricae Novae Planetarum" Theoricae Novae Planetarum presented a version of Claudius Ptolemy geocentric system in a more colloquial and comprehensible way. Based on a series of Peuerbach's lectures at Bürgerschule in Vienna that were transcribed by Regiomontanus. The book introduced the "New Planetary Theory of Georg von Peuerbach" based on the already successful Ptolemaic system, this new theory presented the physical realities of eccentric planetary spheres. In his model of the sun Peuerbach removed simple eccentric shells and added partial orbs, some of which were eccentric and some concentric to the center of the world. Similar models for the planets replaced the body of the sun with an epicycle sphere carrying each planet.
