Wikipedia
ellipticity
Flattening is a measure of the compression of a circle or sphere along a diameter to form an ellipse or an ellipsoid of revolution (spheroid) respectively. Other terms used are ellipticity, or oblateness. The usual notation for flattening is f and its definition in terms of the semi-axes of the resulting ellipse or ellipsoid is f l a t t e n i n g = f = a − b a . {\displaystyle \mathrm {flattening} =f={\frac {a-b}{a}}.} The compression factor is b a {\displaystyle {\frac {b}{a}}\,\!} in each case; for the ellipse, this is also its aspect ratio.

ellipticity
Ellipticity refers to the measure of the deviation of a shape from a perfect sphere (or a circle in two dimensions). It is typically used in the study of celestial bodies like planets and stars to define the extent of how their shapes differ from an ideal sphere. It is also a key term in describing the shape of elliptical galaxies. In another context, particularly in optics and electromagnetism, it describes the state or degree of polarization of a wave.
Webster Dictionary
Ellipticitynoun
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 /
