How does an alteration in eccentricity of the orbit affect the elliptical and circular nature of it?

1 Answer

Eccentricity is the measure of how much a figure deviates from being circular. In an orbit, a less circular one will be more elliptical.

Explanation:

Eccentricity is the measure of how much a figure deviates from being circular. By increasing the eccentricity, an orbit will be more elliptical and by decreasing eccentricity, the orbit will be more circular.
