A possibility is discussed that there are interstellar meteoroids among those detected by ground based instrumentation. It appears that about 0.2--10% of the total number of the meteoroids have hyperbolic orbits. There are different points of view on possibility to detect a meteoroid having an infinite orbit. One may expect theoretically that many of the recorded hyperbolic meteoroids are interstellar. Hence, some hyperbolic orbits may be either erroneous or belong to the meteoroids which were born in the Solar System. A criterion of selection of the real interstellar particles is given in the present paper. The Kharkiv catalogue of orbits of meteoroids with the masses greater than 10-6 g, which produce faint radiometeors, was used.
