Kepler's Geometrical Model for the Distances of the Outer
Planets
In Kepler's model, a planet moved within a spherical shell with inner and
outer radii defined by the limiting spheres of the regular polyhedra. For
the outer solar system, the orbits of Saturn, Jupiter and Mars were thought
to move on spheres separated by a cube, a tetrahedron and a dodecahedron.
