One Comet - Two Showers
If you are wondering how
just one comet can produce two meteor showers it is quite
simple.
In May the Earth encounters the stream
of debris at the Ascending Node, and the radiant appears in the Southern
sky to produce the Eta Aquarids.
The Earth meets the stream again in
October, but at the Descending Node, so the shower radiates from the Northern
sky in Orion.
