NASA: Meteor threat clashing with Earth is bigger than you think


NASA's senior member has warned that the threat of a meteor on Earth is greater than we could imagine.

Jim Bridenstine said at the conference of the Planetary Defense Conference on Monday, "The reason NASA takes this seriously is something you call the" laughing factor ", referring to the scientific theories that seem too ridiculous to be likely.

"It's basically about protecting the only planet we know now to receive life, and that's the planet Earth," he added. "We have to make sure that people need to understand that it's not about Hollywood. .

Bridenstine noted that in February 2013, a meteor measuring 20 meters (65.6 feet) in diameter, traveling at 40,000 miles per hour, entered the Earth's atmosphere and fell over the Chelyabinsk region of central Russia.

Meteorites – small pieces of rock broken by larger asteroids orbiting the Sun – fell on people in the region, and a fireball struck the sky, the BBC reported at the time.

The meteor came with loud bangs and a huge explosion that broke windows and destroyed buildings across the region, Bridenstine added on Monday. He had 30 times the energy of the atomic bomb in Hiroshima, he added.

More than 1,400 people were taken to hospital for injuries related to the meteor crash. Many of them were hit by flying glass, CNN said.

"I wish I could say these events are exceptionally unique, but they are not," Bridenstine said on Monday.

He added that, according to NASA's modeling, these events will occur every 60 years. He added that on the very day of the Chelyabinsk meteor crash, another major asteroid reached 17,000 miles from Earth, but it missed.

Scientists at this week's Planetary Defense Conference, which is biannually planning to discuss how the world can defend itself against potentially dangerous asteroids and comets in case any of them resemble Earth, the conference said in a statement.

In a scenario like this, NASA measures the speed and trajectory of the object and decides whether to avoid the collision by diverting the asteroid or evacuating the affected area, Bridenstine said.
