Great circles through the two poles are called lines or meridians of longitude and connecting is axis rotation. All these other surfaces would have boundaries and sphere is only that lacks boundary with constant positive Gaussian curvature. The pseudosphere is an example of surface with constant negative Gaussian curvature. The centers of all ordinary spheres pencil lie on line passing through and perpendicular to radical plane

Moreover a sphere orthogonal to any two spheres of pencil is all them and its center lies in radical plane . Numerous other closed convex surfaces have constant width for example Meissner body. Therefore sphere is closed

The shortest distance along surface between two distinct nonantipodal points sphere length of smaller arcs unique great circle that includes . Consequently a sphere is uniquely determined by that passes through circle and point not the plane of .

The sphere is only imbedded surface that lacks boundary or singularities with constant positive mean curvature. If the spheres intersect an imaginary circle all of pencil also pass through this but ordinary they are disjoint have no real points common
