Each face of the planetary Icosahedron displays part of the (nearly spherical) planetary surfaces. The triangles are folded so that adjacent triangles are joined exactly at their closest edges. The cut-out pattern forms the complete globe with the North and South Poles at opposite vertices. The icosahedron is a 20-sided polyhedron with each side made up of an equilateral triangle.
