From 2 minutes and 6 seconds through the end of that video, is well worth your time.
Comet 209P/Linear is parallel to Earth's orbital plane around May 19 through May 20, 2014,
and we enter that debris trail May 23 through May 25, 2013, for 30 hours, with the peak density forecasted May 24, 2014 at the 7th hour Universal Time,which should be 1 am Central Daylight Savings TIme.
3 Hours, 52 minutes, and 50 seconds of debris we'll be traveling through, with the center of the peak at 7:21 UT would mean
we would enter the dark area at 11:25 pm Central Daylight Time, May 23, 2014,
and come out of the dark area at 3:17 am Central Daylight Time, May 24, 2014.
But my question now is :
Isn't most of that comet's debris trail moving with the Comet?
If so, then, wouldn't most of the danger be out of the way ?
Wouldn't Comet 209P/Linear ONLY be a threat of major proportion IFthe comet reached the parallel to the orbital plane crossing, directly between Earth and the Sun,at the exact time the Earth was directly behind it in relationship to the Sun?
Or,
is there that much debris left behind from all the orbits Comet 209P/Linear has made before now?
But if that were true,
wouldn't we have already experienced some of its meteorite shower during previous passes through its' orbital trails?
