and it appears that the comet reaches perihelion on 9/11/11.
I'm ignorant when it comes to this stuff. Could you tell me what "perihelion' IS? And also, do you have a link to the size of the comet?
It simply means that an object (In this case that's Elenin) has reached its closest or farthest distance from the object it's orbiting (In this case
its the closest distance to the sun)
It's "orbital period" is around 40.000 years so it'll roughly be at this point again in 40.000 years if nothing happens to change its orbit.
I don´t know how the size was estimated 31 Miles, I can´t find a source for this claim either. Maybe Red Cloak can elaborate?

going out on a limb here, but..... anyone else get the feeling this comet might be a front? perhaps there is indeed a real comet, but what if there
is something else MUCH bigger expected to pass during these time frames.
sure a 30mile comet would be disaterous if it hit us, but I keep hearing things about pole shifts. I don't think a comet of this size is near
capable of causing such a drastic event. just odd nasa says betelgeuse may or may not go supernova and now a massive comet may or may not pass
close. something dosen't add up to me.
It's of course possible that this is just a prequel to something much bigger or a fear mongering tactic to inject more fear in the human consciousness
which could positively influence their agenda, no one knows.
For as far as I've researched, Elenin's closest point to Earth will be 0.2 Au (About 30.000.000 KM or 18.000.000Mi) on 16Oc 2011.
To address the bold part in your post:
IF Elenin´s size is indeed the same as stated in the OP then a pole-shift would be a welcomed sight compared to what would happen if Elenin actually
If scientists have mistaken Elenin's trajectory or we are being fed false information and Elenin will indeed impact our planet (Highly unlikely IMO),
none of the (higher?) lifeforms we know of on our planet would survive.
Best case scenario (If it was made entirely of ice), the force of the impact (Due to its speed of 85.000 Km/h or 50.000 Mph) will be around 4.5
Billion MT (Note that the estimated yield of all nuclear weapons on this planet combined is around 5.000 MT).
tl;dr Although the chances of Elenin impacting the Earth the near future are close to non-existent IMO, If it indeed hits us, you better be
ready for the afterlife no matter where on the planet you are located at.
Edit: Wait, just thought of something. Won't Elenin first have to go THROUGH the asteroid belt? If that's true then isn't it very much
possible that it may be hit by a few asteroids, consequentially changing its orbit around the sun to one where it may hit us?
About the possible Supernova of "Betelgeuse".
Don't worry about it! Sure it's mass is around 20x that of our sun and sure it "may go" supernova today, next week or in a few million years but we
are too far (600+ ly) from it to be in any danger.
All we will see is a bright light very much like our sun for a few weeks.
Also: Betelgeuse is a few hundred light-years away from Earth, she may have already become a supernova hundreds of years ago and the light from that
event is still on its way here.
As long as we are on earth we are in no danger of being killed from a supernova (At least in the coming few thousand years) since there is only 1
"star" (White dwarf) close to the earth that when it goes nova, it could harm us and that star is IK Pegasi.
Although this process will take millions and millions of years and would be even farther from our planet by the time it goes nova (If it ever goes
nova that is), it's still possible that it may effect life on earth on greatly since if IK Pegasi would go nova in the future, it's would be a big
one- unlike Betelgeuse which will just go "poof" compared to IK Pegasi.
tl;dr don't worry about dying because of a star going Super Nova in the coming few thousand years+. The closest Super Nova candidates are too
far from Earth to be a threat.
I'm kind of a science-nerd, couldn't resist the temptation
