The eccentricity is zero. The shape of the orbit is a circle.

Explanation:

This question is about eccentricity which is calculated by dividing the distance between the center and focus of the ellipse by the length of the semi-major axis. When the second focus (mostly empty) is situated approximately at the sun, the eccentricity is equivalent to zero. In addition, the shape of this type of orbit is a circle.
