摘要

Numerical integrations of 99 orbits centered on that of Comet P/Lagerkvist (P/1996R2) and of the original orbit were made 70 years backward in time and 200 years into the future. The integrations show that this comet, belonging to the quasi-Hildas (G. Tancredi et al., 1990, Astron. Astrophys.239, 375–380), most likely has been transferred into its present orbit as recently as 1990, ending a phase of temporary satellite capture by Jupiter. The future orbital evolution indicates a stable period for about 100 years, when another close encounter with Jupiter may lead to further drastic changes.
