For an object to be classified as a comet with a highly elliptical orbit, its eccentricity (e) should be significantly greater than 0 but less than 1. In general, the higher the eccentricity, the more elongated the orbit.
- An eccentricity of 0.9200 indicates a highly elongated orbit.
- An eccentricity of 0.1500 indicates a relatively low eccentricity, closer to a circular orbit.
- Eccentricities of 0.0014 and 0.0009 are indicative of nearly circular orbits.
Given the options, the most likely eccentricity for a comet that follows a highly elliptical orbit is:
0.9200
