Origin of the 2006 Orionid Outburst
Abstract
The Orionid outburst observed in 2006 resulted in strong activity, continuing for about four days. We have found that this activity was caused by the dust trails formed by meteoroids ejected from 1P/Halley in -1265, -1197, and -910. These meteoroids had six times the Jovian orbital period, and their orbit was able to intersect the Earth's orbit at the present day because of this mean motion resonance with Jupiter.
