Quasi-Hilda comet

A quasi-Hilda comet (QHC) is a Jupiter family comet that interacts strongly with Jupiter and undergo extended temporary capture by the planet. These comets are associated with the Hilda asteroid zone in the 3:2 inner mean motion resonance with Jupiter. Typically, asteroids in this zone have a semimajor axis between 3.70 and 4.20 astronomical units, eccentricities below 0.30 and inclinations of no more than 20°.[1] Comets can be temporarily perturbed into this group, then gravitationally perturbed back out again.[2]
