400 meter-wide asteroid to make pass by Earth

October 25, 2011A 1300-foot-wide (400 meters) asteroid, which is more than one and a half times the length of a soccer pitch, will pass within 0.85 lunar distances of the Earth on November 8/9, 2011. Discovered on December 28, 2005 by Robert McMillan of the Spacewatch Program near Tucson, Arizona, 2005 YU55 is believed to be a very dark, nearly spherical object. According to NASA’s Near Earth Object Program: “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.” While neither the European Space Agency (ESA) nor NASA has suggested that YU55 poses a threat to Earth, plans to develop a mission to counteract a potential asteroid collision in the future are already underway. The ESA is planning to fire an ‘impactor’ satellite into a ‘test’ asteroid in 2015 to see if the object’s trajectory can be altered.  The Agency is conducting the test mission in light of the minimal threat posed by the 700-1100-foot-wide 99942 Apophis asteroid, which has a one in 250,000 chance of impacting Earth in 2036. –IWO

    If it hits the moon then its just as bad for us because we would lose the tidal movement. Stagnant oceans would not be so good for us me thinks.
    thank you for creating this excellent site.

    I guess we are on the lookout for a new “habital Earth” cause we screwed up the one we are on…it states the goal of Kepler here…
    “The goal of Kepler is to find an Earth-sized planet in the habitable zone [where life could arise], with a one-year orbit.”

    Great solution..spend billions of dollars to find a new one but dont bother helping the current people suffering from disasters here on earth.
    Oh and Um, we better do this fast if the asteroid pans out to be anything.

    • There is no danger from this asteroid…it’s not even on a colision course with Earth but you’ve made an excellent point about the insanity raging on the planet while looking for another planet in space to trash like Earth. If you want to talk trajectories…2000 YA is on a closer trajectory than this asteroid when it swings by Earth in December- though there is no danger of a collision. We get a lot of things that zoom by us because space is anything but pristine.

    Not This again! There was mass panic attack over comet elenin which NASA made many think was a threat. Wasn’t. Now this, NASA says it’s no threat… Which means it’ll probably smack a he hole into earth, lol. Jokes

      I am sorry but you are wrong. NASA, never said Elenin was a threat to the Earth. It was Internet hype and buzz that made people believe that, including myself.

      However NASA does say solar activity and a magnetically charged Nebula coming this way is a threat.

    Oh so we’ve got 100 yrs grace then have we, how often does it fly by? or do they mean its next flyby will be in 100 yrs? And which one are they going to practice on in 2015? All exciting stuff.

    This is just a hunch…..recently all manner of “things” ie old satellites , old telescopes and now this asteriod….coming close to hitting the Earth or passing close by……I m just wondering if this is possibly a massive cover up for the passage of Nibiru…..which incidentally has debris surrounding it and would cause some problems to the Earth and surrounding planets…..this intrigues me ( oh and forgot to mention the “fireballs” that have been streaking aross the sky in parts of the world too)

    • No…Tracey. We are surrounded by more than 3 million asteroids and there are two orbital bands of nothing but rock debris in space in the Solar System- 3,000 dark comets and 1 trillion comets. Quite frankly, it’s an absolute miracle planet Earth has survived this long.

    Comet Elenin posed no threat whatsoever (regarding impact) as clearly explained by NASA, ‘a disappointing, dirty little ice ball’, yet the ravings on doomer sites was astonishing. Now we have a huge Asteroid passing between the Earth and Moon and where are the drama queens? NASA obviously has more credibility after all. But we knew that.

    Hello, I’ve been reading your posts for some time now. I find the information interesting. I enjoy the earth and space sciences. One thing I have always pondered is why the human psyche has always had a sense of dread about the future. Every civilization you read about has some prophecy about the end times. The universe we live in is very dynamic, the earth itself is constantly changing. I think it is important to be aware of these things but not to panic over something that is completely beyond our control. Life is to short to be afraid to get out of bed in the morning.

    • Randy, so true…we should bask in the joy that is set before us each and every day. Fear of the unknown is a primal instinct and with it, comes the introspective existential realization of sometimes just how small we are in relation to the world and forces around us. When you’re a child, the world consists of nothing more than your city block but as you grow older, your view of the world expands. Sometimes we balance this expanding view of the world with a connection to nature and sometimes it is our ego self that expands instead. Either way; the profound lessons found in nature- the forces that both safeguard and perpetuate life should make us appreciate the wonders of living daily. The universe is very dynamic and change is the only constant. To use a quote from Baz Luhrmann: “A life lived in fear is a life half lived.”

    The earth is struck every day by a rock from space. Some burn up before they hit the ground, some don’t. It has been reported we are entering a denser portion of the galaxy which creates a better opportunity and every BIG rock that comes near us doesn’t mean it will hit us. According to some prophecies, the earth will be struck causing major loss of life. Let us not cheer it on by expecting every rock that comes near is THE ONE.

    Do you think that this passing asteroid could be having any effect on our weather systems? Or is it too small? We are seeing such wide spread flooding in areas around the globe, I just wondered with it passing closer than our moon could it be causing anything. When should we be able to see it?

  22. Alvin, is it possible for the solar flares/CME’s to alter the course of this asteroid to where it COULD hit the earth’s atmosphere? seems like a real possiblity since it would also heat up the sunside of the asteroid and provide some propulsion as well as being swept along in the “solar wind”…thoughts?

    Like

    • Technically, it would be possible if there was a highly reflective surface on an asteroid, it could alter trajectory but since nearly all asteroids have very low-albedo ratios, or reflective properties, most theories utilizing the technique of such deflections involves installing a mechanical contrivance on or near the asteroid to achieve this end. Most such devices are known as solar sails. As far as the solar wind itself, remember solar wind is plasma propagating thought the vaccum of space. So it’s transmitting energy, not necessarily velocity and mass.
