About ellipse use for astronomy.
I need to compare excentricity of the 8 planets in Solar System:
Mecury: e=0.2056
Venus: e=0.0068
How can I know what ellipse is more or less oval? About ellipse use for astronomy.

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.

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