Question: what is the relationship between the eccentricity of an ellipse and its shape?
Answer: An ellipse has a critical component called eccentricity (or little e), the extent to which an orbit deviates from a circle. Eccentricity is equal to the distance between the two foci of an ellipse divided by the major axis. Eccentricity tells us the shape of the ellipse and its value ranges from 0 to 1.
