The orbits of the planets are ellipses but the eccentricities are so small for most of the planets that they look circular at first glance. For most of the planets one must measure the geometry carefully to determine that they are not circles, but ellipses of small eccentricity.

One last term related to ellipses should be noted before moving on. This is the concept of the eccentricity of an ellipse. The eccentricity e of an ellipse is defined to be the ratio of the distance between the foci to the distance between the vertices.

If we assign dollar values to the eccentricity of the three ellipses that you drew, then AB would equal $0.10 (ten cents), CD equals $0.60 (sixty cents), and EF equals $0.90 (ninety cents).
