WebMay 5, 2014 · Here are the five Platonic Solids, i.e, those three-dimensional shapes in which all the faces are the same two-dimensional shapes of the same size and all the vertices (corners) of the three dimensional solid touch the inner surface of an imaginary hollow sphere called the Circumsphere. WebA perfect solid is a three dimensional figure, such as a cube, whose sides are all identical. Conveniently for Kepler, there are only five perfect solids: the tetrahedron (which has four triangular sides), cube (six square sides), octahedron (eight triangular sides), dodecahedron (twelve pentagonal sides), and icosahedron (twenty triangular sides).

WebPlacing the 6 planetary spheres between the 5 perfect solids actually leads to spacings for the planets which match the data. (note: to this day there is really no satisfactory theory … Kepler proposed that the distance relationships between the six planets known at that time could be understood in terms of the five Platonic solids enclosed within a sphere that represented the orbit of Saturn. The six spheres each corresponded to one of the planets (Mercury, Venus, Earth, Mars, Jupiter, and … See more In geometry, a Platonic solid is a convex, regular polyhedron in three-dimensional Euclidean space. Being a regular polyhedron means that the faces are congruent (identical in shape and size) regular polygons See more A convex polyhedron is a Platonic solid if and only if 1. all its faces are congruent convex regular polygons, 2. none of its faces intersect except at their … See more Angles There are a number of angles associated with each Platonic solid. The dihedral angle is the interior angle between any two face planes. The dihedral angle, θ, of the solid {p,q} is given by the formula See more The tetrahedron, cube, and octahedron all occur naturally in crystal structures. These by no means exhaust the numbers of possible forms of crystals. However, neither the regular … See more The Platonic solids have been known since antiquity. It has been suggested that certain carved stone balls created by the late Neolithic people of Scotland represent these shapes; … See more The classical result is that only five convex regular polyhedra exist.
