The Ecumenical Agency has begun looking for celestial bodies at a great distance from the planet to destroy them on time. "The surrounding objects on Earth are weak and really small," they said.
Hollywood movies have predicted it long ago and it seems to be one of NASA's biggest fears. Possible Armageddon or Deep Impact are two possibilities, with many different purposes, which have already been seen in the cinema and that the space agency wants to avoid.
With the threat of Bennu, so-called. the asteroid of death, the National Aeronautics and Space Administration has begun exploring celestial bodies at a great distance from the planet, because those close to our orbit are obviously not relevant.
This is Bennu, the "asteroid of death" that may clash with the Earth
"If we find a heavenly object within a few days of impact, it greatly limits our possibilities, so we focused on finding objects near Earth, when they are farther, providing maximum time and opening up a wider range of mitigation opportunities," said he Amy Meinzer, at NASA.
The Earth Defense Strategy from Possible Influence was presented on Tuesday at a meeting of the American Physical Society. In the meantime, chief researcher of the asteroid hunting mission on NASA, in the Laboratory in Pasadena, California, said the procedure would be "tough" and compared it to finding a part of the coal in the night sky.
"Objects near the Earth (NEO) are essentially weak, because they are mostly small and very far from us in space," the scientists argue.

"They are as dark as the printer's toner," said the scientist NASA at the same time in which he added that "trying to detect them against the black of space is very difficult."
Meinzer used the characteristic of the NEO, which allows him to detect them without the need to go to the visible light to perceive: its heat.
"With the NEOWISE mission, we can detect objects independently of the color of their surface and use them to measure their sizes and other properties," the scientist explained. NASA.
