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 Quadrantid shower is one of the regular events in the meteor observer's calendar, producing displays at the beginning of January each year with the zenithal hourly rate usually at around 100. The peak in the activity profile is quite short, being less than a day (Shelton 1965;Bel'kovich, Sulejmanov & Tokhtas'ev 1982). The declination of the radiant is very high at around 50 • , making it essentially a Northern hemisphere shower.…”

The Quadrantid meteor shower is a very regular and prolific meteor shower. As such, one might expect that its parent would be easily recognizable. This is not the case, and numerous comets have been suggested as potential parents. We summarize the situation to date. Recently, an asteroid given the temporary designation 2003 EH1 has been discovered on an orbit that is so similar to that of the Quadrantids that some association between them is probable. The orbit still has some uncertainties and these, together with an orbit that can make fairly close approaches to many planets, make studying its orbital evolution difficult. We have generated, using a statistical model, 500 clones for this body and integrated the motion of these clones back in time for 1000 yr. We find that around ad 1500 the orbit of asteroid 2003 EH1 was very similar to the orbit of the Quadrantids at that date. Further, in 1491, the orbits of a few of these clones were very similar to the orbit of C/1490 Y1 and their sky position also roughly matched that of the comet. Various possibilities are discussed.

“…The Quadrantid shower is one of the regular and major events in the meteor observer's calendar, producing displays on January 3 and 4 each year with a maximum zenithal hourly rate (ZHR) of around 100. The peak activity period is quite short, being generally less than a day (Shelton 1965), and this, coupled with general bad weather in January, means that observations are not as plentiful as might be expected for such a prolific stream, although the number of Quadrantid meteoroids with well-determined orbits is fairly high, Wu & Williams (1992) locating 118 such orbits in the records of the IAU Meteor Orbit Data Center at Lund. The Quadrantid shower was identified as a regular stream as early as 1835 (Fischer 1930;Lovell 1954), and so ranks as one of the first identified streams.…”

The parent of the Quadrantid meteoroid stream

The Quadrantid meteor shower is one of the major showers that produces reliable displays every January. However, it is unique amongst the major showers in still not having its parent uniquely identified. One of the reasons for this may be because the stream, and presumably the parent, lies in a region of the Solar system where near‐resonant motion with Jupiter, coupled with potential close encounters, is possible. Such a combination can lead to a rapid dynamical evolution of an orbit. In particular, it may be possible that the orbit of the parent both satisfies the condition for a close encounter and is in resonant motion, while most of the meteoroids cannot satisfy both conditions. This results in the parent evolving away from the bulk of the stream. To date, two suggestions have been made regarding possible parents for the Quadrantid stream, these being Comet 1491 I and Comet 96P/Machholz. The argument in favour of the first named being the parent is because of the general similarity between the orbits around 1491. The argument for comet 96P/Machholz being the parent is based on the similarity in orbital evolution coupled with a similarity in orbits phase‐shifted by 2000 yr. In this paper we suggest that on both counts asteroid 5496 (1973 NA) is more similar to the Quadrantids, and that even if 5496 is not the actual parent in the strict sense that meteoroids are currently being ejected, it is either likely to be a fragment of the parent or the dormant remains of the parent.
