A dodecahedron is a polyhedron with twelve regular pentagonal faces, three of which meet at each vertex. It is one of the five Platonic solids and has been known since ancient times. The dodecahedron is often associated with the celestial sphere in various mythologies and was said to be used by the ancient Greeks for map projection. Due to its unique geometry, it has applications in fields such as chemistry and crystallography.
