论文摘要
太阳系中小体的传播是由行星相遇的结合驱动的，这些遭遇会导致其轨道和世俗的长期扰动的突然变化。我们提出了一种传播策略，将这两种影响结合到一个单个框架中，以长期快速地传播内部太阳系中的小体。木星的分析世俗扰动中断到数值求解行星相遇，这持续了一小部分模拟时间。将提出的繁殖方法与太阳系中的数值积分进行了比较，从而有效地捕获了计算时间的一部分数值解决方案的性能。我们研究Janus任务目标的轨道历史：（35107）1991 VH和（175706）1996 FG3，获得了其长期动态和非常紧密相遇的频率的随机表示。在过去的一百万年中，发现强烈扰动飞行的可能性很小。
The propagation of small bodies in the Solar system is driven by the combination of planetary encounters that cause abrupt changes in their orbits and secular long-term perturbations. We propose a propagation strategy that combines both of these effects into a single framework for long-term, rapid propagation of small bodies in the inner Solar System. The analytical secular perturbation of Jupiter is interrupted to numerically solve planetary encounters, which last a small fraction of the simulation time. The proposed propagation method is compared to numerical integrations in the Solar system, effectively capturing properties of the numerical solutions in a fraction of the computational time. We study the orbital history of the Janus mission targets: (35107) 1991 VH and (175706) 1996 FG3, obtaining a stochastic representation of their long-term dynamics and frequencies of very close encounters. Over the last million years the probability of a strongly perturbing flyby is found to be small.
