As can be seen below, the great circle is the one that shares the centre with the main sphere itself. The diameter of both the sphere and the great circle coincides. Just as the two-dimensional Cartesian coordinate system is useful on the plane, a two-dimensional spherical coordinate system is useful on the surface of a sphere. In this system, the sphere is taken as a unit sphere, so the radius is unity and can generally be ignored. This simplification can also be very useful when dealing with objects such as rotational matrices. all gomez addams
