Answer 1

If you're talking about the heliocentric view of the solar system (wherein the sun is at the center of the solar system) then you're talking about Copernicus. However, if you're talking about the geocentric view of the solar system (where the earth is at the center of the solar system) then you're referring to Ptolemy.
