1 answer

A comet typically has the most eccentric orbit among the given options. Comets can have highly elliptical orbits that take them far away from the sun and then bring them close to it during their periodic visits to the inner solar system. On the other hand, Earth and Mercury have more circular orbits, while the orbit of an asteroid can vary in eccentricity but generally is not as eccentric as that of a comet.
