Next Week's Asteroid Flyby Shows Earth is in 'Cosmic Shooting Gallery'

The people of Earth are not doing enough to protect their home planet from the threat of an asteroid impact, scientists Tuesday (5 February) said, as tracking a space rock scheduled to a close next week shaven

the asteroid because I spend unusually close to Earth on February 15 -. called 2012 DA14 - was discovered last year by amateur astronomers with the help of a grant from a nonprofit agency. While the asteroid 2012 DA14 poses no risk of hitting the Earth, there are probably hundreds of thousands of rocks as if it were there, said its discoverers.

"We live in a cosmic shooting gallery and is a reminder we have to keep doing our job to find these things and to prevent the single preventable natural disaster, which is the asteroid impact, "said Bruce Betts, a planetary scientist at the planetary Society, the nonprofit space research and organization exploration that helped sponsor the discovery of asteroid 2012 DA14 .


" we are not doing enough "to find potentially dangerous asteroids, Bruce told reporters today during a conference call. "We're doing more than we were 15 years ago, and these surveys are helping. The're discovering faster. To be sure, we need much higher rate of discovery."

A person who is pitching in to help is Jaime Nomen, a dentist by day and a hunter night asteroid surgeon. Nomen is part of the team at the Observatoire de La Sagra in Spain who discovered 2012 DA14 about a year ago. [ Asteroid 2012 DA14 flyby: Fact and Fiction (Video) ]

Asteroid 2012 DA14 is about half the width of a football field (150 feet or 45 meters), and it will fly within 17,200 miles (27,700 kilometers) from our planet on Friday, February 15, zoom closer to the planet than the ring of orbiting satellites geoestacionaria.


No long before the discovery of February 2012, the asteroid, Nomen and his team won a grant object shoemaker near Earth sponsored by the Planetary Society that allowed them to update the CCD camera in one of its telescopes, increasing the number of images the team can snap objects quick movements.

Projects such as the search for La Sagra can sometimes find asteroids that slipped through the cracks of the surveys conducted by the largest NASA who are responsible for the most discoveries of asteroids near Earth every year, Nomen said. Still, there are so many space rocks midrange, as 2012 DA14, and move so fast that a survey could be done at a point in the sky one day and not see anything, but the next day, an asteroid could do can observe there, he said.

"Those small objects can appear at any time," Nomen said. "Of course there are many who remain descubrir."


Mientras that the Earth is safe from 2012 DA14, an asteroid of that size would do much harm if it did impact our planet. A rock of similar size hit Tunguska, Siberia , in 1908, and flattens about 500,000 acres of forest over an area about the size of Tokyo.

and there is much more where you come from.

"the objects are out there and eventually they will hit," Betts said. "it's not a question of whether we will have catastrophic effects, is a question of when."

with a little advance warning of an asteroid impact on the scale of about 10 years, scientists have series of strategies that could be used to alter the trajectory of a space rock on a collision course. But if such a threat was discovered a few months or days ahead of time, the best we could do would probably have to evacuate the area, Nomen said.

NASA will hold another press conference on the approaching asteroid 2012 DA14 on Thursday (February 7) at 2 pm EST (1900 GMT). Visit SPACE.com on Thursday for a complete news coverage of that event
