A highly elliptical orbit for a comet indicates a high eccentricity value. The range of eccentricity (e) for orbits varies from 0 to 1, where:
- e = 0 represents a perfect circle,
- e < 1 represents elliptical orbits,
- e = 1 is parabolic (the trajectory of an object at the threshold of escaping gravitational influence),
- e > 1 indicates hyperbolic trajectories.
For highly elliptical comets, the eccentricity is typically close to 1. Among the options given, the value that most closely represents a highly elliptical orbit is:
0.9200
So, the likely eccentricity of the new comet is 0.9200.
