Ptolemy's geocentric system stood for 1,500 years until Nicholas Copernicus, a polish astronomer, proposed that the planets have the Sun as the fixed center, which their motions are to be referred. That the Earth is a planet, which besides orbiting the Sun annually, also turns once daily on its own axis; and "that very slow, long term changes in the direction of this axis account for the precession of the equinoxes." While Copernicus's theories, in terms of accuracy, were about the same as Ptolemy's. Copernicus's theories did correctly explain many key concepts missing in Ptolemy's work.
