Before Copernicus started insisting that the sun was the center of our solar system, scientists like Tycho devised elaborate data charts showing the Earth at its center. Now designer Piotr Kaczmarek has created gorgeous diagrams comparing Tychonian and Copernican views.

You can see the Tychonian vs. Copernican models in motion - and fiddle with the view - via a movable chart at Digital Orrery. Andrew Vande Moere writes over on Information Aesthetics:

Digital Orrery by Piotr Kaczmarek is as simple as beautiful: it shows our solar system according to the Copernican (sun-centered) or Tychonian (earth-centered) model.

Users can rotate the whole solar system by dragging the outer ring or allow it to move automatically by adjusting a slider in the top left. Specific calendar dates can be set, individual planets can be traced and speeds can be changed.


Check out the Digital Orrery and play with competing models of the universe.
