Small Circle (Wikipedia)

A circle constructed by a plane crossing a sphere not in its centre. Small circles always have smaller diameters than the sphere itself. A small circle can also be defined as being formed by the intersection of a sphere and a plane that does not pass through the centre of the sphere, as it does for a Great Circle.

The small circle has a larger curvature (more arc) than a great circle, and hence, a segment on its circumference does not represent the shortest path between two points on a spherical surface.
