This paper presents the results of a study of the existence of nine near-Earth meteorite-producing
groups in asteroidal orbits, containing sporadic reballs from the IAU MDC-2007 database, sporadic
meteors from the SonotaCo database, meteorites namely, L5, L6 and H4−H6 ordinary chondrites
and an ureilite, for which atmospheric and orbital parameters are known from instrumental observations.
Orbits of the selected members of meteorite-producing groups were classi ed as asteroid orbits
according to the Tisserand parameter Tj > 3.1.
Dynamic links between the members of the identi ed meteorite-producing groups and
instrumentally observed known meteorites which were taken as a reference for the search of potential
group members were tested using orbital similarity criteria, in particular the Drummond criterion
DD and the Southworth and Hawkins criterion DSH. As a result, several meteorite-dropping
sporadic reballs and small meteors, whose orbits are similar to the asteroid orbits of nine known
meteorites, were detected and reckoned as possible members of meteorite-producing groups.
