Quasi-Hilda comet : ウィキペディア英語版 | Quasi-Hilda comet A quasi-Hilda comet (QHC) is a Jupiter-family comet that interacts strongly with Jupiter and undergoes extended temporary capture by it. 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 AU, eccentricities below 0.30, and inclinations of no more than 20°.〔 Comets can be temporarily perturbed into this group and then perturbed back out again.〔 Eight percent of the comets that leave the 3:2 resonance end up impacting Jupiter.〔 ==Known quasi-Hilda comets== These numbered comets belong to the group of quasi-Hilda comet:〔 39P/Oterma was a quasi-Hilda before a close approach to Jupiter in 1963.〔 77P/Longmore falls outside of the bulk distribution because of its large eccentricity and inclination.〔 Comet Shoemaker–Levy 9 impacted with Jupiter in 1994.
