“…). Several authors have proposed associating the Taurid‐Encke complex with additional minor streams such as the N. and S. Piscids of September–October, the S. Arietids, and the N and S. Chi Orionids (in December) among others (see Babadzhanov and Obrubov for a review).…”

We propose that the Taurid meteor shower may contain bodies able to survive and be recovered as meteorites. We review the expected properties of meteorite‐producing fireballs, and suggest that end heights below 35 km and terminal speeds below 10 km s−1 are necessary conditions for fireballs expected to produce meteorites. Applying the meteoroid strength index (PE criteria) of Ceplecha and McCrosky (1976) to a suite of 33 photographically recorded Taurid fireballs, we find a large spread in the apparent meteoroid strengths within the stream, including some very strong meteoroids. We also examine in detail the flight behavior of a Taurid fireball (SOMN 101031) and show that it has the potential to be a (small) meteorite‐producing event. Similarly, photographic observations of a bright, potential Taurid fireball recorded in November of 1995 in Spain show that it also had meteorite‐producing characteristics, despite a very high entry velocity (33 km s−1). Finally, we note that the recent Maribo meteorite fall may have had a very high entry velocity (28 km s−1), further suggesting that survival of meteorites at Taurid‐like velocities is possible. Application of a numerical entry model also shows plausible survival of meteorites at Taurid‐like velocities, provided the initial meteoroids are fairly strong and large, both of which are characteristics found in the Taurid stream.

“…According to the value of T j = 3.0 calculated by Equation , the NEA 2004MB6 is moving on a comet‐like orbit that suggests a Jupiter‐family comet origin of the asteroid. As shown by Babadzhanov and Obrubov (), if a NEA is an extinct cometary nuclei, then it might form a meteoroid stream at the period of its cometary activity. Such a meteoroid stream should produce observable meteor showers at present and the statement of their link with the asteroid also proves its cometary nature.…”

Three bright fireballs belonging to the August θ‐Aquillid (ATA) meteor shower were photographed by the Tajikistan fireball network in 2009. Two of them are classified as the meteorite‐dropping fireballs according to the determined parameters of the atmospheric trajectories, velocities, masses, and densities. Detection of the more dense bodies among cometary meteoroids points to a heterogeneous composition of the parent comet, and supports the suggestion that some meteorites might originate in the outer solar system, in the given case from the Jupiter‐family comet reservoir. A search for the stream's parent was undertaken among the near‐Earth asteroids (NEAs); as a result, the asteroid 2004MB6 was identified as a possible progenitor of the ATA meteoroid stream. Investigation of the orbital evolution of the 2004MB6 and the fireball‐producing meteoroid TN170809A showed that both objects have similar secular variations in the orbital elements during 7 kyr. The comet‐like orbit of the 2004MB6 and its association with the ATA shower suppose a cometary origin of the asteroid.

“…Since the nodal distances of stream meteoroids orbits will be equal to 1 AU at four different values of x, during one cycle of its variation, four meteor showers can be formed by a single meteoroid stream (Babadzhanov and Obrubov, 1992). These four meteor showers consist of a night-time shower with Northern and Southern branches produced at the pre-perihelion intersection with the Earth's orbit, and of a day-time shower also with Northern and Southern branches originated at the post-perihelion intersection.…”
