This paper presents the results of the
analysis of possible existence of nine near-Earth
meteorite-producing groups in asteroidal orbits, consisting
of sporadic fireballs 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 – and their
plausible parent bodies, that is, near-Earth asteroids
(NEAs). Orbits of the selected members of meteorite-
producing groups were classified as asteroidal according
to the Tisserand parameter T J > 3.1.
In order to test the link between meteorite-producing
groups in asteroidal orbits and their plausible parent
bodies, we carried out an investigation into the possible
existence of some known NEAs that move in similar
orbits. Based on the orbital similarity, determined using
the Drummond (D D ) and Southworth & Hawkins (D SH )
orbital similarity criteria, some associations between the
identified NEAs, known meteorites in asteroidal orbits
and small, as well as meteorite-dropping, meteoroids have
been suggested. As a result, several meteorite-dropping
sporadic fireballs and small meteors, whose orbits are
currently similar to the orbits of known meteorites, have
been detected and reckoned as possible members of the
groups in asteroidal orbits; their plausible source regions
have also been considered.
