The two and three body mean motion resonances with Jupiter and Mars (and possible with Earth) may have a significant effect on the dynamics of very young close asteroid pairs and families. The best known example is the influence 9:16 resonance with Mars to some members of Datura family. It is evident, that the evolution of this family can be properly reconstructed only when this fact has been taken into account. One of the results of resonance perturbation may be the temporary compensation of the Yarkovsky drift in the semimajor axis. Studying this relationship may greatly improve the age estimation of asteroid pairs and families. In this note we give a list of some close asteroid pairs in the vicinity of mean motion resonances.

受三体共振强烈干扰的近距离小行星对清单

木星和火星的两个和三个物体的平均运动共振(以及地球可能发生的共振)可能对非常年轻的近距离小行星对和家庭的动力学产生重大影响。最著名的例子是9:16与火星的共鸣对曼陀罗家族某些成员的影响。显然,只有考虑到这一事实,才能适当地重建该家族的进化。共振扰动的结果之一可能是半长轴方向Yarkovsky漂移的临时补偿。研究这种关系可能会大大改善小行星对和家庭的年龄估计。在本说明中,我们列出了平均运动共振附近的一些小行星对。
