What if the Sun orbited the Earth ?

Earth-centered vs Sun-centered models of the Solar System

Digital Orrery

This excellent interactive animation created by Piotr Kaczmarek creative director at Dynamic Diagrams.  lets you to switch between the  (real) Copernican, sun-centred model of the solar system and the Tychonian (earth-centred) model. Unlike other orrery visualizations I’ve seen this one goes the extra mile and includes sun shading, moons and the asteroid belt.

Switch between models using the tabs at the bottom right. You can rotate the system by dragging the outer ring.  There are also some speed,  and date settings at the top of the screen.
