Abstract: The proportion of possible interstellar particles to interplanetary ones, observed with different techniques, was found to be much higher for small particles obtained from high power radars and cosmic dust detectors in comparison with results of photographic observations from the IAU Meteor Data Center in the range of large meteoroid particles. This contradiction may be explained by different mass distributions of interstellar and interplanetary particles. Moreover, the break in the mass distribution function in the mass range of 10^-10 - 10^-11 kg corresponds to the mass range limit of inclusions of interstellar origin in meteorites. This coincidently shows as a possible explanation of the break in the mass distribution function caused by different physical processes leading to populations of interstellar and interplanetary particles.
