When the orbital eccentricity of a planet is close to 1, it means its orbit is a highly elongated ellipse. A higher eccentricity indicates that the orbit is more stretched out rather than circular.

For a comet that follows a highly elliptical orbit, its eccentricity is likely to be 0.9200. Eccentricities close to 1 indicate a more elongated orbit, characteristic of comets.
