A great circle, also known as an orthodrome or Riemannian circle, of a sphere is the intersection of the sphere and a plane which passes through the center point of the sphere. (Wikipedia)

The answer is Great Circle.

It's not just any circle, it's a great circle. A great circle is a circle of a sphere that has the same center as the sphere (so same radius and diameter too) http://en.wikipedia.org/wiki/Great_circle
