“…To confirm a closeness of the orbits, the D r criterion is applied with the same threshold as the D SH criterion. In the cases of the large dispersion in the angular elements of orbits, Asher et al (1993) suggested slightly modifying the D criterion that is used with the same threshold value as the D SH criterion and defined by formula…”

“…At present, more than 40 NEAs are claimed to be associated with the Taurid complex, alongside comet 2P/Encke (Asher et al 1993;Porubčan et al 2004Porubčan et al , 2006Babadzhanov et al 2008a;Rudawska et al 2012a,b). Many other associations between asteroids and meteor showers have been identified, examples being Babadzhanov et al (2009Babadzhanov et al ( , 2012Babadzhanov et al ( , 2013Babadzhanov et al ( , 2015, Trigo-Rodrigues et al (2009), Madiedo et al (2013), Micheli et al (2016).…”

The evolution of the nominal orbits of comet 96/Machholz 1 and the near-Earth asteroid (196256) 2003 EH1 under the effects of gravitational perturbations from the major planets was investigated over a time interval of 28 000 yr. Several criteria for measuring the differences in orbits were used to determine when the orbits were most similar to each other and this was found to be approximately 9500 ago. This supports the hypothesis that the comet 96P/Machholz 1, the near-Earth asteroid (196256) 2003 EH1, and the Quadrantid meteoroid stream form a complex of related objects.

“…The most recent list of such sub-streams is given by Porubčan et al (2006). Further support for this hypothesis came when Clube & Napier (1984) showed that several Apollo asteroids had orbits that were very similar to the Taurid stream while a decade later, Asher et al (1993) suggested that the complex of meteoroid streams, comet 2P/Encke, and the then known associated Apollo asteroids, could all have been formed by the fragmentation of a giant comet 20 to 30 ky ago. Since that date several, other authors have claimed associations between NEOs and the Taurid complex, the present number of candidates being well in excess of 100.…”

Aims. 2P/Encke is a short period comet that was discovered in 1786 and has been extensively observed and studied for more than 200 years. The Taurid meteoroid stream has long been linked with 2P/Encke owing to a good match of their orbital elements, even though the comet's activity is not strong enough to explain the number of observed meteors. Various small near-Earth objects (NEOs) have been discovered with orbits that can be linked to 2P/Encke and the Taurid meteoroid stream. Maribo and Sutter's Mill are CM type carbonaceous chondrite that fell in Denmark on January 17, 2009 and April 22, 2012, respectively. Their pre-atmospheric orbits place them in the middle of the Taurid meteoroid stream, which raises the intriguing possibility that comet 2P/Encke could be the parent body of CM chondrites. Methods. To investigate whether a relationship between comet 2P/Encke, the Taurid complex associated NEOs, and CM chondrites exists, we performed photometric and spectroscopic studies of these objects in the visible wavelength range. We observed 2P/Encke and 10 NEOs on August 2, 2011 with the FORS instrument at the 8.2 m Very Large Telescope on Cerro Paranal (Chile). Results. Images in the R filter, used to investigate the possible presence of cometary activity around the nucleus of 2P/Encke and the NEOs, show that no resolved coma is present. None of the FORS spectra show the 700 nm absorption feature due to hydrated minerals that is seen in the CM chondrite meteorites. All objects show featureless spectra with moderate reddening slopes at λ < 800 nm. Apart for 2003 QC 10 and 1999 VT 25 , which show a flatter spectrum, the spectral slope of the observed NEOs is compatible with that of 2P/Encke. However, most of the NEOs show evidence of a silicate absorption in lower S/N data at λ > 800 nm, which is not seen in 2P/Encke, which suggests that they are not related. Conclusions. Despite similar orbits, we find no spectroscopic evidence for a link between 2P/Encke, the Taurid complex NEOs and the Maribo and Sutter's Mill meteorites. However, we cannot rule out a connection to the meteorites either, as the spectral differences may be caused by secondary alteration of the surfaces of the NEOs.

“…The initial mass and particle diameter can be further constrained by taking into account that, according to the analysis of the orbital elements, the meteoroid belonged to the Daytime ζ-Perseid stream, which is a part of the Taurid complex. It has been postulated that the objects (Clube & Napier 1982;Steel et al 1991;Asher 1991;Asher et al 1993;Steel & Asher 1996). In fact, Comet 2P/Encke has been proposed as the parent body of the Daytime ζ-Perseids (Jenniskens 2006).…”

On 10 June 2012, an Earth-grazer meteor which lasted over 17 s with an absolute magnitude of -4.0 ± 0.5 was observed over Spain. This work focuses on the analysis of this rare event which is, to our knowledge, the faintest Earth-grazing meteor reported in the scientific literature, but also the first one belonging to a meteor shower. Thus, the orbital parameters show that the parent meteoroid belonged to the Daytime ζ-Perseid meteoroid stream. According to our calculations, the meteor was produced by a meteoroid with an initial mass ranging between 115 and 1.5 kg. During its encounter with Earth, the particle travelled about 510 km in the atmosphere. Around 260 g were destroyed in the atmosphere during the luminous phase of the event as a consequence of the ablation process. The modified orbit of the remaining material, which left our planet with a fusion crust, is also calculated.
