This paper investigates how three-body mean motion resonances with planets like Jupiter and Mars influence the dynamics and age estimation of close asteroid pairs and families, emphasizing the importance of resonance effects.

Contribution

It provides a list of asteroid pairs near mean motion resonances and highlights the impact of these resonances on asteroid dynamics and age determination.

Findings

Resonances can temporarily counteract Yarkovsky drift.

List of asteroid pairs affected by mean motion resonances.

Resonance effects are crucial for accurate age estimation.

Abstract

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