Near-Earth asteroids among the Iota Aquariids meteoroid stream

Abstract

It is shown that the near-Earth asteroids 2002JS2, 2002PD11, and 2003MT9 have very similar orbits to each other and probably a common origin. We investigate the orbital evolution of these asteroids under the perturbing action of the planets and calculated the theoretical shower parameters for any meteor shower that may be associated with these asteroids. Finally we searched the existing catalogues of meteor showers and fireballs, and found that activity has been observed corresponding to each of the theoretically predicted shower. We conclude that this asteroid-meteoroid complex is the result of a cometary break-up.

Investigation into the relationship between comet 96P/Machholz 1 and asteroid 2003 EH1

“…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 potentially hazardous asteroid 2007CA19 as the parent of theη-Virginids meteoroid stream

“…For example, it turned out that the Piscids meteoroid stream has three associated NEOs 1997GL3, 2000PG3, and 2002JC9, which move within the stream and are dormant fragments of a larger comet-progenitor of this complex (Babadzhanov & Williams 2007;Babadzhanov et al 2008c). It was shown that the NEOs 2002JS2, 2002PD11, and 2003MT9 with very similar comet-like orbits are related to the ι-Aquariids meteoroid stream, and this asteroid-meteoroid complex is the result of a cometary break-up (Babadzhanov et al 2009). It was proved that the NEO 2004CK39 moving on a comet-like orbit is associated with the ν-Virginids meteoroid stream and, very likely, is the dormant comet (Babadzhanov et al 2012).…”

The σ-Capricornids complex of near-Earth objects

“…It consists of many substreams and has both comet 2P/Encke and more than 40 NEAs moving by the orbits within it and being dormant or dead cometary fragments in reality (Asher et al, 1993;Babadzhanov, 2001;Porubcan et al, 2004Porubcan et al, , 2006Babadzhanov et al, 2008a;Rudawska et al, 2012a,b;Madiedo et al, 2013). It was shown that such meteoroid streams as Piscids, i-Aquariids, m-Virginids, Scorpiids also contain from one to several large NEAs of cometary origin, and these asteroid-meteoroid complexes are the results of a cometary break-up (Babadzhanov et al, 2008b(Babadzhanov et al, , 2009a(Babadzhanov et al, , 2012(Babadzhanov et al, , 2013. The presence of large sized cometary bodies within meteoroid streams was recorded in the data of observations.…”
