Asteroid to give Earth a close shave next week

Asteroid to give Earth a close shave next week


Quote:
A huge asteroid will zoom past Earth next week at such a close distance that amateur astronomers should be able to spot it, specialists said on Wednesday.

Measuring between 150 and 600 meters across, asteroid 2007 TU24 would inflict devastating regional damage were it to hit Earth, but there is no risk of any collision, they said.

It will fly by on Tuesday, being around 534,000 kilometers (334,000 miles) from the Earth at its closest point at 0834 GMT, according to a Near Earth Object (NEO) database compiled by the University of Pisa in Italy.

"For a brief time the asteroid will be observable in dark and clear skies with amateur telescopes of three inches (7.5 centimeters) or larger," NASA said on its NEO site.

2007 TU24 will make the closest approach of any known potentially hazardous asteroid of this size or larger until 2027, NASA said, adding that objects of this size come close to Earth about every five years or so on average.

The rock was discovered only last October under a surveillance program run by the University of Arizona.

According to the Minor Planet Center of the Paris-based International Astronomical Union (IAU), the closest detected approach by an asteroid was on March 31, 2004 by 2004 FU162, which came within 6,500 kilometers (4,000 miles) of Earth.

The day after 2007 TU24's terrestrial flyby, asteroid 2007 WD5 is expected to come within 26,000 kilometers (16,250 miles) of Mars, a distance that is less than a whisker in space terms.

2007 WD5 ignited a brief surge of excitement among astronomers after it was discovered in November.

Initial computations of its orbit gave a roughly 1-in-25 chance that it might whack into Mars on January 30, providing a celestial show that could be monitored by US and European scoutcraft there.

Measuring about 50 meters (165 feet) across, it would have delivered an impact equivalent to a three-megaton nuclear weapon. A rock of this size exploded over Tunguska, Siberia, in 1908, felling around 80 million trees over 2,200 square kilometers (850 square miles).

But further calculation showed that the hoped-for big splat would be a big miss.

"It's highly unlikely that it's going to hit," said NEO expert Benny Peiser of Liverpool John Moores University in northwestern England, as the odds of a collision by 2007 WD5 fell to around 0.01 percent, or one in 10,000.

Asteroid to miss Mars, may hit Earth



Quote:
An asteroid that has a one in 20 chance of striking Mars on January 30, might just fly past, which would probably make it target Earth at some point in future.

Designated 2007 WD5, the 160-foot wide asteroid was originally identified as a possible risk to Earth, though later analysis showed that it actually might be on a collision course with Mars.

According to a report in Discovery News, Donald Yeomans, a planetary scientist at NASA's Jet Propulsion Laboratory in Pasadena, California, has said that the odds are that the asteroid is going to fly right past Mars.

In the long run, that may not be good news for Earth, which could find itself in the asteroid's path at some point in the future. "Something of this size could take out a fairly large metropolitan area," said Yeomans.

But unlike the 1908 Tunguska event, when a large asteroid exploded over central Siberia with the force of a large nuclear bomb, now there would be advance warning of a possible strike, as well as the tools and knowledge to divert the threat

I read somewhere that this comet might be the end of the world... well, I don't believe that's the case... To be honest I don't believe in that that world is going to end in 2012 either... The world isn't going to end until the sun burns out and when that happen we're far away from here allready! xD

Is this for real? Then it would be fun to watch and learn about. Asteroids and space and those stuffs interest me a lot. I hope I will get to see this asteroid and I hope that there are no asteroids aimed at earth for ever.

So close yet so far away. Should we be worry ? Maybe watching to much movies and we became a bit paranoid with end of the day asteroid hitting earth....

Well it is very much possible. Nearly all scientist believe that what ended the dinosaurs was an asteroid. It's not all that uncommon that every x million of years that we get hit by a huge one.

nothing is impossible with it. Every asteriod has its own orbit, if its orbit hits the earth then we can't do nothing but to intercept it in space. (like in some movies, lasers and missiles are used to destroy it, another is the movie Armageddon)

i watched the science chanel about something like this. it is a possibility that that comet can hit earth. the worst part is, is that they can't deflect it because it's to big and they can't blow it up because all the peices will come back and hit us anyways. IF it does happen... we are doomed Smile

Heard report tonight that the asteriod missed the earth by some 330,000 miles but astronomers studied it.

wow kool !!!

ill wait with a rope in hand !!! tied to an anchor... when the asteroid zooms pass ill hook it and go with it into the endless space ! with a fish bowl over my head !!!! Smile

That would be so kool ! Very Happy
