Question

a measured of the amount by which an elliptical orbit deviates from a circle is called blank

Answer 1

A measure of the amount by which an elliptical orbit deviates from a circle is called **eccentricity**. Eccentricity is a numerical value that describes the shape of an ellipse, with values ranging from 0 (which represents a perfect circle) to values approaching 1 (which represent increasingly elongated ellipses).
