The article says a lot of recent headlines are talking about using nuclear weapons to attack asteroids. As previously reported, NASA is actually drafting the plan to destroy an asteroid flying by nuclear weapons. This theory is called HAMMER, which is the task of emergency response reduction for super high speed asteroid. But scientists probably don't need to use such a response to deal with the asteroids, such as The Empire State Building, Benu. The numbered 101955 asteroids are scheduled to approach the earth in 2135. It is probably much simpler to transfer such threats.

NASA source spectrum interpretation resource safety weathering identification detector (OSIRIS-REx) Michael, a flight dynamics manager, said: "as long as the half of the asteroid is painted with different colors, it will change the thermodynamic properties and change its orbit. To be exact, it will involve launching a spacecraft to change the color of the asteroid in some way.

The article said, we also do not know much, this is why the launch of NASA OSIRIS-REx detector to Benu, the aim of this task is to get back in 2023 of this asteroid sample.

The article quoted the U.S. "Washington Post" reported that there is a minimal chance of berua collided with the earth, about 1/2700. This asteroid is not large enough to destroy human beings, but it will cause some serious damage. The OSIRIS-REx detector will strengthen the study of the asteroid, and NASA will continue to collect data, either to exclude or improve the possibility of impact.

The article said, but don't worry if the possibility of Benu, it collided with the earth becomes too high, the laws of physics will support a nuclear attack much simpler solution, as long as we can on the painting.


All objects in the solar system are attacked by a large number of tiny particles from the sun, which will bring a little pressure. These particles are insignificant to our earth's orbit, because the earth is of great mass, and the mass of Benu is only about 13 times the mass of Pyramid in Giza. In contrast, this is very light. Taking into account the Benu need 120 years to fly near earth and it will fly over the distance, if scientists can make a part of it is more vulnerable to the effects of solar radiation, and that this would be enough to change it a little path and avoid us. To do that, we need to change the part of the asteroid's surface and let it absorb more radiation -- for example, paint the side. Scientists first need to better study the orbit around the sun to determine the best action steps.

The article says, as usual, what we have to say is that the earth won't be hit by this huge asteroid.

The article says, of course, we have to worry about some of the asteroids, because we didn't follow them as we said before. The US government only requires NASA to track asteroids about a stadium size. The asteroids smaller than this size may avoid radar and cause significant local damage rather than the 120 year warning period of Bernoulli.

The idea of destroying asteroids with nuclear weapons is a great science fiction, the article says. But we should spend more time worrying about what we don't know what is more little planet threat, instead of worrying about the scientists are tracking those who can easily distract the asteroid.
