F. ellipticit['e].] Deviation of an ellipse or a spheroid from the form of a circle or a sphere; especially, in reference to the figure of the earth, the difference between the equatorial and polar semidiameters, divided by the equatorial; thus the ellipticity of the earth is 1/29966. Note: Some writers use ellipticity as the ratio of the difference of the two semiaxes to the minor axis, instead of the major. --Nichol. From WordNet r 1.6 [wn]: ellipticity n : the property possessed by a rounded shape that is flattened at the poles; "the oblateness of the planet" [syn: {oblateness}]
