Copernicus thought up Heliocentric theory, the theory that the universe's center is the sun (or that our solar system's center, at least, is the sun, which is true!).
Ptolemy thought up geocentric theory, the theory that the unverse's center is the Earth.
Copernicus's theory went against the Church, and he and Galileo got in a lot of trouble because of it. This was all during the Scientific Revolution (see http://en.wikipedia.org/wiki/Scientific_revolution for more about that!) in 1543.

Ptolemy thought the Earth was the center of the universe and that the Sun and all planets went around the Earth. Copernicus said the Earth and all the planets went around the Sun.
