- NASA conducted a fearsome simulation to see how an asteroid could not hit the planet.
- Participants managed to fend them off, but divested part of New York.
- The fragment was only 165 too large 260 feet wide (50 to 80 meters), but would produce more energy on impact than several nuclear bombs, and the only way to ensure the safety of the people was the entire evacuation of New York City.
- NASA said this situation is unlikely. However, the exercise was necessary to "help decision makers practice a true asteroid impact."

NASA simulates the fearsome scenario of preventing an asteroid from striking the Earth process, breaking off a fragment that is raging to New York and forcing an evacuation of the entire city.
In an April exercise at the Planetary Defense Conference, NASA participants, the Federal Emergency Management Agency (FEMA), and other federal agencies had eight years to prevent an asteroid from hitting the Earth. However, when NASA and space agencies around the world came together to distract the asteroid, they broke away.
During the simulation, the 500- to 850-foot-wide asteroid (1

However, this distraction resulted in 165 to 260 feet (50 to 80 meters) of fragment breaking off the asteroid. This ended up "on a certain collision course with Earth," and the scientists had to watch from the ground to find out where they would hit the planet.
They learned ten days before their attack that they were going to New York City, and that would come into the atmosphere at 19,000 km / s (19,000 km / s).
This would "produce a big fireball or" megabolide "and release five to 20 megatons of energy when impacted: For comparison, the atomic bombs fell on Hiroshima and Nagasaki together generated 0.04 megatons of energy.
Those involved in the simulation found that evacuation of the entire city of New York was the only way to ensure human safety, reported "USA Today."
NASA says the risk of such a disaster is low, but they need to be prepared.
NASA said the simulation "is intended to help key decision-makers practice real asteroid influence," but reassured people that, "No asteroid at present which is likely to affect Earth in the next century. "
Paul Chodas, Director of NASA's Near Eart Center h Object Studies and author of the simulation, said: "We have to challenge ourselves and ask the tough questions."

He said that a scenario hit an asteroid A big city was unlikely and an asteroid that hit Earth would probably hit the ocean.
Chodas told NASA, "Every day we ask, what if?"
"You do not learn anything if you do not study the worst case every day."
FEMA also said such simulations are important in preparing the agency for major disasters.
Leviticus Lewis of FEMA Response Operations said: "Bringing together the disaster management community and the scientific community is critical to preparing for possible future asteroid impacts."
NASA takes the danger of asteroid impact seriously. NASA Administrator Jim Bridenstine told the conference that people would have to accept the idea that an asteroid could crash more seriously on Earth.
He said that people often dismiss him for being ridiculous, probably because of the "gagging factor" or scientific theories. "
But he said the risk was real, even though people tend to think of Hollywood movies when they consider the possibility.

"We need to make sure people understand that it's not about Hollywood. It's not about movies. It's about ultimately protecting the only planet we know now to house life, and that's the planet Earth, "he said.
NASA and other space agencies around the world are studying the sky for ear Earth Objects (NEOs) Asteroids and Comets.
It is said that the actual work that prepares for an impact is "mostly out of the public eye".
