OpenStudy (anonymous):

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.

OpenStudy (ash2326):

the higher the eccentricity the orbit is more oval if eccentricity is close to 0 then the orbit is near circular

Okay, thanks both
