Copernicus vs Tycho! Fight!

While we’re on the subject of the Solar System and illustrative animations, the orrery at this web page enables you to compare Copernicus’ heliocentric model of the solar system – wherein the sun is at the centre, orbited by other bodies – with the view, propounded by Tycho Brahe, of an Earth-centric universe.


As well as looking beautiful, the animation really underlines how complex the Tychonian model had to be to accommodate the observed motions of the planets in the earth-centric model.

Lesson? Don’t try to force the data to fit your theory; the simplest solution is usually the best.
