Sorry for the bad English.

Each time that I see the Perseids from Italy I see too some Eridanids 
coming from South and with a radiant under the horizon, Eridanids with 
slow earthgrazing traiectories.

On the topic: too other comets doing origin to meteor showers have 
today big MOIDs, the fact that 273P has today a MOID of 0.17 AU it's 
not significative, perharps in the past this MOID was near zero.

On the specific topic: I'm doing a search for write the page on 
Eridanids for italian Wiki
and I found that exist many meteor radiants in Eridanus in August, the 
principal are Eta Eridanids and Epsilon Eridanids and .... their 
parent it's not 273P! Their parent comets are probably the following

http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=C%2F1854+L1&orb=1

the second comet do origin at a meteor shower too on Mars.
But ... the two comet are parabolics! Perharps in reality they are 
long period comets?
Best greetings.
