Tycho was not a Copernican, but proposed a "geo-heliocentric" system in which the Sun and Moon orbited the Earth, while the other planets orbited the Sun. Although Tycho's planetary model was soon discredited, his astronomical observations were an essential contribution to the scientific revolution.
The most renowned geo-heliocentric model is that put forth in 1583 by Tycho Brahe, referred to as the Tychonic system. It is a little-known fact that this model remained the most widely accepted con guration of our Solar System for at least a century a er Tycho Brahe’s death in 1601.
