Asteroid YU55 to Approach Earth on November 8, 2011

Postby dyn » Fri Sep 09, 2011 23:02 UTC

It won't destroy the Earth, but it may have certain influence. You can be sure some people will start to panic when they see this in the news. :)

"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. The attached animated illustration shows the Earth and moon flyby geometry for November 8th and 9th when the object will reach a visual brightness of 11th magnitude and should be easily visible to observers in the northern and southern hemispheres. The closest approach to Earth and the Moon will be respectively 0.00217 AU and 0.00160 AU on 2011 November 8 at 23:28 and November 9 at 07:13 UT.

Discovered December 28, 2005 by Robert McMillan of the Spacewatch Program near Tucson Arizona, the object has been previously observed by Mike Nolan, Ellen Howell and colleagues with the Arecibo radar on April 19-21, 2010 and shown to be a very dark, nearly spherical object 400 meters in diameter. Because of its approximate 20-hour rotation period, ideal radar observations should include tracks that are 8 hours or longer on multiple dates at Goldstone (November 3-11) and when the object enters Arecibo's observing window on November 8th.

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. As well as aiding the interpretation of the radar observations, collaborative visual and near infrared observations could define the object's rotation characteristics and provide constraints upon the nature of the object's surface roughness and mineral composition.

Since the asteroid will approach the Earth from the sunward direction, it will be a daylight object until the time of closest approach. The best time for new ground-based optical and infrared observations will be late in the day on November 8, after 21:00 hours UT from the eastern Atlantic and western Africa zone. A few hours after its close Earth approach, it will become generally accessible for optical and near-IR observations but will provide a challenging target because of its rapid motion across the sky."

"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."

Well, nothing will happen until November 8-9, 2011. It won't collide with anything, but still 0.85 lunar distances from the Earth is very close astronomically speaking. Perhaps it will influence people on more subtle levels.

You are too pessimistic! :)

I wouldn't worry about asteroids and comets, after all we survived millions of years without any serious impact. Jupiter and Saturn are gravitational giants in our solar system, they absorb most of the really dangerous stuff. Btw, a lot of comets are debris of old planet Phaeton (also known as Marduk), many times frozen ocean water, which explains all the ice around us.

If fate is 100% responsible for everything, then self-determination is a waste of time, therefore Universe is sub-optimal which is never true. Self-determination takes precedence over fate or external forces, because this Universe is not wasting anything. Fate can influence you as much as you allow it, if you are walking around submitted to God of your choosing, then you will influence your future that way, if you decide to take charge of your life, Universe will respect your decision.

Most powerful weapons: intent and decision. Your will is the law and power.

I like comets! :D I remember Hail Bop (I think it was called that) , I think it was visible for maybe a week? I used to look at it for ages. Yes, I am a bit strange ;)

hairsplitting …
optimistic fatalist is an absurdity and in good fun.
I agree with your statement.
I like to say this:
my optimism is related to the near future. I know that a crash on all areas is overdue. not the world - but the human beeing
is in shambles of its megalomania. so any comet or geographic pole shift or 3.worldwar or what else is one of many concomitants accelerating the turbulences.
it is imperativ to get ready for the time after. the current vale of tears is a pain and degrading...

I didn't feel the comet that was supposed to hit us at the end of last month? Maybe it hit the other side of the planet? Color me disappointed.

Comets/meteors/meteorites etc. are a part of your well-balanced super-hero breakfast. Next to getting struck by lightning, or falling in radioactive waste, it's one of your best ways of getting super powers.

FEB 2011:

Amazing video of massive solar flare erupting from surface of Sun



JUN 2011:
Solar Flare Sparks Biggest Eruption Ever Seen on Sun
http://news.nationalgeographic.com/news/2011/06/110608-solar-flare-sun-science-space/
Chamberlin said it will take some time to calculate the energy and mass of electrons and protons blasted into space. But he noted the volume occupied a space hundreds of times bigger than a single Earth.[...]


AUG 2011:


This increased activity may trigger disturbances to Earth's power grids and similar. It is also disturbing our society, of course science cannot measure this aspect, but some people think there is a correlation between solar activity and societal chaos, usually manifested as protests, economic troubles, which all usually lead to local and world wars.

For instance, the Great Flare of 1918 that spawned Hitler's ideologies.
Or April 6th, 1994 ... that flare lasted 100 days in Rwanda.
And, why else would we have invaded Vietnam?

Maybe Allen Wrench is riding on it.
