O článku:
The radar meteor orbits of the most recent version of the IAU
among them have been examined with the aim of to determining a
real proportion of interstellar orbits in this database. It is
shown from the tests that a large proportion of meteors with
hyperbolic orbits is concentrated to the radiants of meteor
showers and to the ecliptic plane. These belong to the orbits of
typical interplanetary behaviour following annual and diurnal
variation. In spite of this they highly increase a proportion of
retrograde orbits. A vast majority of hyperbolic orbits, even for
the highest measured velocities, may be considered as a
consequence of measurement errors. We estimate that only a
fraction of 10-3 of the total numbers of 39 145 Harvard
radar data in the MDC could be ascribed to real interstellar
meteors. It means that from the number of 970 hyperbolic orbits in
the Harvard radar catalogues only about 5% can be recognized as
interstellar.
