If YU55 DID hit the earth, would it be an extinction level event ?

yes, its huge, the lucky ones would die in the impact or tsunami, the rest would die from the ash cloud,freeze, starve,or die of thirst.

lol

it's only 400 metres wide

not nice if you're within 200 miles of it, I don't suppose, but no, no ELE, sorry.

lmao.

nope

its time to redefine "ELE" really, because a 400 m wide asteroid may not send out the way of the Dinosaur, however do you know how to grow, harvest, and preserve food as our ancestors did?

the sun won't break through the ash cloud for a year, the weather would change dramatically,volcanos would erupt, earthquakes would be constant.

Lets just say it would take out a nice size continent.

It would make a 6 mile crater. Ruin somebody's day but not an ELE.

no its only 200m wide.

Should be alright if your in a Spectrum MSV.

No, it would be a population reduction event.

Nope

But I can see a new word appearing if it does "Mega-Disaster" media will eat this up nicly, lol

it'd be fun to watch, from a (great) distance.

The important question is,

should I bring in my tomato plants.

sorry not shure how to insert the link..

Hypothetically, if it DID hit Earth, if it hit somwhere in the Middle East, would it end our reliance on oil? Would it put an end to religious wars about who gets to inhabit the "Holy Land"? Could this be why Obama finally relented and is pulling troops out of that area?

Just wonderin...

I read that it's the size of an aircraft carrier.

Some of it would burn up during reentry.

Doom cancelled due to lack of interest

it's only 400 metres wide it's really to small for even teaser ELE

Not an E.L.E. object, but it would make a helluva a damage and could kill millions

Space Weather .com now says that it is 4000 m wide!!!!

4000 as in four thousand!!!!!!!!!!

NO

Not whatsoever.


If it lands in the ocean (which it almost certainly would), it's unlikely it would ever be known.
