What is 2005 YU55 Asteroid?
The 2005 YU55 is a giant asteroid which was first discovered in 2005 by Robert McMillan who serves as the Head of the Spacewatch Program of University of Arizona that is funded by NASA and at that time it was about 2.3 million kilometers aways. It is one of those space rock which has a massive body and is said to orbit the sun after every 14 years atleast once. It has remained on the spotlight since its discovery and there were speculations about the probability of its impact which at that time was marked to be a potentially hazardous object. But later, when it was mapped using the Arecibo Radar Telescope in 2010, scientist were able to know its precise location and classify its properties who accordingly came to conclusion that this space object may simply miss the earth and that its probability for any impact or threat is very low for the span of another 100 years or a century and there is nothing to fear about it.
This 2005 YU55 asteroid was reported to be as powerful as 65,000 atomic bombs which if collided with earth can create a crater of 2,000ft deep and 6miles wide. There are also some measures which are documented to be taken for any probability of impact and these includes few ideas which can be effective to deflect the asteroid from its orbit away from our living planet.
How can 2005 YU55 Asteroid be deflected?
Over the years, the scientists have been discussing and planing various measures so as to come up with an effective and proper way to deflect any of the heavenly bodies from striking the earth's surface in the future and in this regard there are three know ideas which is believed to be worthy enough for the purpose. Some of these are as follows:-
The first suggestion is that of using nuclear energy by detonating a nuclear warhead right onto the asteroid such that it is deflected out of its orbit away from the earth. Eventhough it is considered effective and ideal for emergency situation, it may not be an ideal one as there are possibilities of creating political disturbances and there is even the concern that such approach may turn the space rock to bits.
Secondly, it is suggested that mirrors should be brought into use with the help of many spacecraft which can vaporize the space rock by reflecting the rays of sun towards it.
Thirdly, the easiest and the most common thought would be to rush a spacecraft against the asteroid and force it to deflect using its own gravity that might be enough for the purpose.
Conclusion: 2005 YU55 Asteroid passing Near Earth
As of now, scientist claims that the 2005 YU55 flyby will not turn out to be of any threat and that they are preparing themselves to monitor and image the event with the help of radar echoes which can be used to transform it into 3-D shapes and analyze it more properly than what is known till date. Since it will be moving towards the sun in the first place, it will not be visible for the humans but later with the solar elongation on November 8, one can view it through small telescopes and which can be sighted for many hours till November 9, 2011.
