J2000 heliocentric ecliptic orbital elements of 160 Near-Earth Comets
Originator: National Aeronautics and Space Administration
The dataset includes all the standard orbital elements for a given Near-Earth Comet, such as eccentricity, inclination, and perihelion and aphelion distance. It also includes acceleration-related force parameters for comets for which those factors are known.
Plot distance at perihelion versus orbital period for all near-earth comets in the dataset:
