There was a time not long ago where scientists believed the earth was the center of the universe, like Tycho. However, after Copernicus had his revolutionary discoveries we learned that we, and the rest of the solar system, in fact orbit the sun.
This website has a cool demonstration of how the solar-sytem would look under both models. Of course, Copernicus was right, but it is still cool to see what the solar system would look like if Tycho was. Use the faint buttons in the lower right corner to change between models.
The other cool thing I like about this animation is that you can see the relative length of orbits for each planet.
