A sphere is characterized by having zero faces, zero edges, and zero vertexes. The three dimensional ball shape is void of any edges, corners, or vertexes, which makes it unique from all other shapes. A cube, for example, has 6 faces, 12 edges, and 8 vertexes. However, the very nature of the sphere means that it would not have these properties. The word sphere originates from the Greek word sphaira, which means globe or ball.
