5 asteroids are dangerously close to the Earth

Reported by Talia Lakritz

The planet Earth is surrounded by tens of thousands of pieces of space rock. If one of them crosses the atmosphere and hits the surface of the Earth, the consequences could be devastating at the global level.

NASA's Global Defense Coordination Office consolidates data from the Near Earth Objects and NASA Global Asbestos Alerts Research Center to closely monitor potential objects pose a threat.

Here are five objects close to Earth that are a little too close for their comfort.

In 1908, an asteroid razed 1,300 square kilometers of forest near the Podkamennaya River Tunguska in Siberia, Russia.

In what has become known as "the Tunguska event", NASA reports that a 1,000-million-kilogram asteroid traveling at a speed of 54,000 km at the time was entering the area. 39, Earth's atmosphere over the Podkamennaya River Tunguska in Siberia, in 1908. It separated about 50 000 km from the ground.

Most of the asteroid having been consumed during the explosion, the explosion did not leave crater impact. No casualties have been reported. It has however destroyed 80 million trees.

The researchers were not able to access the site until 1927 due to difficult weather conditions. They found trees whose branches and bark had been torn off under the effect of a shock wave.

A meteor exploded on Chelyabinsk, Russia, in 2013 with the force of a nuclear explosion

The "Chelyabinsk meteor" exploded in the Earth's atmosphere at a speed of 64,000 km / hour and broke up at 24 km from the ground, according to Space.com.

Reuters reported that the shockwave damaged buildings, broken windows and caused 1,200 injuries.

A few months later, scientists recovered part of the Chebarkul Lake meteor in Russia. They estimated that the meteor had a diameter of about 17 m and weighed 11,000 tons.

NASA then created the Global Defense Coordination Office.

An asteroid named 2017 BX slipped between Earth and Moon in January 2017

The asteroid rose to 260,000 km, roughly two-thirds of the moon. At about 14 meters in diameter and 267,000 kilometers an hour, it was too small and too slow to pose a real threat. Dave Mosher, of INSIDER, however, said his last-minute detection was "just another example of our blindness to the millions of NEOs that could project onto our planet and release a lot of energy." energy of many atomic bombs ".

In April 2017, a "potentially dangerous" asteroid the size of a skyscraper flew within 18 million kilometers of the Earth.

Because it was flying so close to Earth (about 4.6 times the distance between our planet and the moon), the 2014 asteroid JO25 received the label "potentially dangerous asteroid". But NASA said the 600-meter rock "will fly safely over the Earth" and should not reappear for more than 400 years.

An asteroid 110 m wide was discovered only one day before its ground flight in April 2018

A NASA asteroid named 2018 GE3 has traveled 191,000 km in flight, about half the distance between the Earth and the Moon, in April 2018.

NASA estimated that the asteroid measured three to six times the size of the meteor that had exploded above Chelyabinsk. Scientists spotted her just 21 hours before her closest flight to Earth, but said there was no chance of it having an impact.
