  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.
