Spheres are spherical, with no base, and have no flat surfaces. Cones have a flat, circular base, with a circular altitude protruding from the edges of the circle. The altitude's diameter slowly diminishes until all edges reach eachother.
A cube has twelve edges.
there are 12 edges.
a cylinder has 0 edges
17 edges
There are zero edges because its a sphere and spheres have no edges
Spheres have no edges.
Spheres
First of all, edges is spelt wrong. And secondly, spheres don't have edges.
Spheres don't have any edges.
spheres
vertices=1(one) edges=no edges faces=no faces
A sphere has 0 edges and 0 faces. Thus implying that it has no verticies either. This is obvious. Spheres are round.

The question is based on a false premise, and so cannot be answered.
polyhedrons need flat face and edges, corners which cylinder cones don't have.
None. THEMIS is a NASA mission to investigate the auroras in the Earth's atmosphere. It will provide information on the planet's magnetosphere. Although there are spheres involved, they are not called THEMISPHERE.
