Copernicus' Geocentric Model of the Universe

copernicus is famous for his heliocentric model. He was the first, but famous person to really say out loud and yell it from roof tops. The earth rotates around itself once a day - that's how we get seasons. And also, this explains the motion of some other planets in the sky. If you observe venus, you never see venus on the other side of where the sun is. Ra if there's the sun the earth, you'll never see venUS on the otherside,. Because venus is closer to the sun than the earth.
