sphericity
Globe-shaped geometric property
Sphericity is the quality or degree of being spherical—how closely something approaches the shape of a perfect sphere.
The term appears in geology to describe particle shapes, in manufacturing for ball bearings, and in medicine for red blood cells.
The sphericity of the Earth is not perfect; it bulges at the equator.
