The eccentricity (e) is a number which measures how elliptical orbits are. If e=0, the orbit is a circle. All the planets have eccentricities close to 0, so they must have orbits which are nearly circular. Last modified October 9, 2008 by Randy Russell. What's New on the Site? When Nature Strikes - …
