MINOR PLANET 2002 EX12(=169P/NEAT) AND THE ALPHA CAPRICORNID SHOWER
2010
Astronomical Journal
Minor planet 2002 EX 12 (=comet 169P/NEAT) is identified as the parent body of the alpha Capricornid shower, based on a good agreement in the calculated and observed direction and speed of the approaching meteoroids for ejecta 4500-5000 years ago. The meteoroids that come to within 0.05 AU of Earth's orbit show the correct radiant position, radiant drift, approach speed, radiant dispersion, duration of activity, and distribution of dust at the other node, but meteoroids ejected 5000 years ago
