What does ellipticity mean?
The state or quality of being elliptical; a measure of how elliptical a shape is, typically expressed as a ratio of the distance between the foci to the length of the major axis.
Example
"The ellipticity of the galaxy's orbit around the center of the cluster was a key factor in determining its stability."
