Model of a Small Stellated Dodecahedron
notes: label: Description
content: This model of a small stellated dodecahedron is made of metal painted gray. A rod from one of the vertices extends down to a round wooden stand painted black. No maker's marks are on the model or the base.
label: Description
content: This polyhedron has twelve identical faces that are intersecting pentagrams produced by extending the edges of the faces of a regular dodecahedron. The twelve vertices are also identical. The surface is one of two first described by Johannes Kepler in 1619, and now known as a Kepler-Poinsot solid.
