Diagram depicting the basics of the Tychonian geocentric system. Basically, the objects on blue orbits (the Moon and the Sun) revolve around the Earth. The objects on orange orbits (Mercury, Venus, Mars, Jupiter, and Saturn) revolve around the Sun. All is surrounded by a sphere of fixed stars. The system is essentially geocentric, though everything except for the moon revolves around Sun.

Distances are of course just generalized, though it is important that the minor planets are always "tied" to the Sun while the major planets can be on either side of the Earth.
