2005 YU55 - BOOM Headshot!!

I still believe this asteroid is more of a problem for us , if there were to be a problem, than anything else at this time.

I read nasa suggests that it won't hit earth for at least another 100 years minimum. That being said I will take Nasa comment to be saying that it will hit earth at some point, though they reassure that it is a minimum of 100 years.

Does anyone know what the degree of error is in making these "minimum calculations?

Hi my friend end cheers, but only whit Heineken or maybe Erdinger I' love that beer .. xD

I' post link to my thread here some new information are there, so we all can by update ..

Peace ..

Looking at the latest info from JPL, The moon is going to get it closer than us....around a 40K mile miss, not much, any experrts here weigh in on gravitational effect coming so close to us/moon?

What about if it strikes the moon, what would be our risks?

ssd.jpl.nasa.gov...

The gravitational field of 2005 YU55 is negligible as far as Earth and Moon are concerned. It will not hit either body during this close approach, but there is always the possibility that it will hit one of them in the distant future. However, accurately calculating the trajectory beyond a century into the future is tricky, because multiple perturbations from the inner planets make the orbit somewhat chaotic, and therefore unpredictable over very long time periods.

Thanks for the info:

JPL is showing the MOID to be lower now .0010 Au, but no update to the moon distance, prior the MOID was.0021 and the moon was .0016 Au. Just wonder what the moon distance is now?

If you use Facebook, all the information you could ever want and more about Elenin is on this page: Comet Elenin-Official Facebook Page

You can even find the guy who discovered the comet on there from time to time making comments, as well as a link to his personal page.

Here's a link to the Stereo images made into a movie (takes a bit to load though) Elenin - Stereo

They also talk about Honda, some asteroids, and a few other bodies in space.

MOID stands for "Minimum Orbit Intersection Distance". That is the closest that the two objects (Earth and 2005 YU55) could get in the present epoch. It does NOT mean that the asteroid will get this close in November, although it will not be far off.

NASA would not post data that shows an impact event, atleast not until it had been officially announced to the world.
There is a high chance that publishing such data would result in mass panic. We all know how much TPTB love 'money', imagine the effect that such data would have on their beloved stocks and share prices.

NASA have stated themselves that YU55 was of concern to them. It is close enough to be an impact candidate, especially when you accept that orbital calculations have a 'margin of error'.

Be prepared for 8th November 2011 at 11:30pm UTC.

st.

Orbital calculations do indeed have a margin of error, but that margin is exceptionally small for this particular asteroid's close approach to Earth. There is absolutely no chance whatsoever that it will hit our planet in November, so please stop worrying about it!

edit on 28-8-2011 by Mogget because: (no reason given)

Who is worried? You should only worry about the things you have control over.

Depends what you call 'exceptionally small'. You are also assuming the correct close approach data has been publicly published. As I have pointed out, NASA would not publish impact data.

So by all means, stick your head in the sand. I, however, will be keeping my most prized possessions close at hand, just incase I need to move quickly.

2005 YU55 was discovered in, well, 2005. It's orbital period of 1.22 years has provided plenty of data to predict it's orbital trajectory. In fact,

using the Goldstone radar operating in a relatively new "chirp" mode, the November 2011 radar opportunity could result in a shape model reconstruction with a resolution of as fine as 4 meters. Several days of high resolution imaging (about 7.5 meters) are also planned at Arecibo.

Please also note the 'edge on' view of the trajectory, a full 120,000 km above the earth and lunar ecliptic plane.
