(Plato made these geometrical shapes the basic components of his cosmos in the Timaeus.) Kepler began with the sphere of the earth.

They are the tetrahedron, made of four equilateral triangles the cube, made of six squares the octahedron, made of eight equilateral triangles the dodecahedron, made of twelve pentagons and the icosahedron, made of twenty equilateral triangles. The five regular solids, also known as the Platonic solids, are symmetrical polyhedrons in which each face is the same regular polygon. Kepler’s flash of insight, which he describes in terms evocative of divine revelation, was that the spaces between the orbs of the six planets were delimited by the five regular geometric solids. ![]() In 1595, while he was working as a mathematics teacher in the Austrian city of Graz, he hit upon the answer. He puzzled for a long time over the question of why there were gaps between the celestial orbs in the Copernican system, and he also wondered why there were six planets, as opposed to some other number. Kepler was introduced to Copernicus’ work as a student at the University of Tübingen by his professor Michael Maestlin (1550 – 1631). ![]() One of the very first people to accept the physical reality of the Copernican system was the German astronomer and mathematician Johannes Kepler (1571 – 1630).
