2005 YU55 - BOOM Headshot!!

can someone please tell me what size matters for these object to be a menance?

thank you!!

Here's some good information on asteroid impact with Earth What if an asteroid hit the Earth?

It mentions the outcome of various sized objects hitting Earth ranging from a house, a 20 story building, and upwards of a mile wide.

how can i not star you for that...great info thank you!!!!!!!!!!!!!!!!!!!!!!

Wow..Awesome thread!! This year so far is going to be NUTS. I have so many damn dates to worry about, its hard to sleep at night..lol

JPL Database This is nuts to, Showing on the 7th of this month, the object pretty much hits the earth. The distance actually goes to 9.0E-4au, wtf that means. This is probably one of the closest ive seen objects come using this nifty little tool. After seeing the link on the destruction based upon size, how do we tell how large this object is? 2011 EY11, I hope its not too large and breaks up in our system

They say it's 5 to 15 meters,and it will be about 125,000 km from us.or 1/3 the distance of the moon.

200 mtrs is equivalent to hiroshima bomb

15mtr will impact though i think...not too much damage though..or it will get disintegrated upon entry...still it will put up a show somewhere for lucky people

i correct myself...

the size of a house..lets say 19- 50 mtr..hiroshima..





20 story building..200 feet....TSAR BOMB



more...ARMAGEDDON

I believe the crater In Arizona was created by a object the size of around 15 meters, your average house in diameter. So although The smaller Rock won't be a ELE or Continental affecting impact, locally you can be sure it'll make quite a large bang.

i believe TPTB have ways to change its course to save us, nukes, missiles, comet landing crafts really i think there would have been alot of research and science into this since the movie Deep Impact or even earlier.

It is going to miss by 120,900 miles. That is like 1/3 the distance to the moon.

I like watching that video.

My only gripe is when it says that this has happened six times in the past.

That is still very hotly contested, and no proof shows one way or the other.

so tomorrow watch the skies..maybe ur lucky...we have a nuke traveling close to home..

That's the thing... There is NO evidence that was given about the comet, except for the announcement of it's discovery in December 2010. Since then it seems to have disappeared because no astrologers, or anyone with a decent telescope that should be able to see the object, can actually find it in space.

50 meters. Big house. Heavy too.

Scientists now believe that the crater was created approximately 50,000 years ago. The meteorite which made it was composed almost entirely of nickel-iron, suggesting that it may have originated in the interior of a small planet. It was 150 feet across, weighed roughly 300,000 tons

phage *COUGH*..i was drinking coffee when i read 50mt....only after i realized you're not talking on tomorrows :/


btw thank you for today's image..i have to star you for that..awesome ^^

Worth a bump I think...

Asteroid 2005 YU55 To Approach Earth Nov 8 2011
by Staff Writers
Pasadena CA (JPL) Mar 11, 2011

Near-Earth asteroid 2005 YU55 will pass within 0.85 lunar distances from the Earth on November 8, 2011. The upcoming close approach by this relatively large 400 meter-sized, C-type asteroid presents an excellent opportunity for synergistic ground-based observations including optical, near infrared and radar data.

Source: spacedaily.com

Interestingly...

Although classified as a potentially hazardous object, 2005 YU55 poses no threat of an Earth collision over at least the next 100 years. However, this will be the closest approach to date by an object this large that we know about in advance and an event of this type will not happen again until 2028 when asteroid (153814) 2001 WN5 will pass to within 0.6 lunar distances.

I still believe we need to keep an eye open for this one.

I read somewhere that this 2005 YU55 may collide with ELENIN somewhere around November.

It does travel close to earth and 400M wide would make a resonable dent.

Even if it hit the moon it would put on a good show....

Maybe that collision needs to have its own thread?

reply to post by guessing


Hum,interesting,never thought of that angle.

You can play around with impact sizes at this website, I'm not sure it will answer all of the questions you have of an extinction level impact though.

That's the problem Physics says for an object to be that size and spherical it will have a high mass I.E be made of dense materials. See this article above for example from Space Daily. So to have formed a sphere it must have high enough gravity. I understand its rotational period is low. Therefore to have formed a sphere it must be made of a dense material. Denser than earth. see this for example

www.spacedaily.com...

If you were on such a dense object you would weigh more, if you were from there and came to earth you would weigh less
