Ordering of the five planetary orbits in terms of the
nesting of the five regular solids. This hypothesis formed
the center piece of Kepler's 1596 The secret of the universe
(Mysterium cosmographicum).
Despites rather poor agreement
between this model and observations, Kepler would cling to this
idea to the end of his life. He issues a second edition of
the book in 1621.
