An asteroid could hit Earth in September 2019

On Monday, September 9, 2019, an asteroid about 40 meters in diameter could hit the planet Earth at 44,000 kilometers per hour.

The impact may resemble a devastation that of the asteroid, which fell in 1908 in Tunguska (Siberia). It has destroyed an area of ​​2,000 square kilometers (50 kilometers in diameter) and toppled 80 million trees in the taiga

But the specialists do not lose sleep because they hit the earth, the asteroid QV89 of 2006 represents no danger to life on the planet.

"The data we have now , the likelihood of a collision is equivalent to a train crossing a blind road without being able to see or hear whether the train is coming, but one day passes every 15 hours Would you pass? "explains Ettore Perozzi of the Italian Space Agency ( ASI). This probability is currently estimated at 1 in 11,428.

The star of 2006, QV89, as it is officially named, occupies seventh place on the list of potentially the most dangerous asteroids on Earth in the next one hundred years.

Bliss At this time, 816 asteroids with a non-zero impact probability were identified, which is 4% of the current 19,560 near-Earth asteroids.

The risk of each asteroid is taken into account on the Palermo scale, the size of each star, the probability of impact, and the time remaining until the eventual collision.

At the top there is a star with a diameter of only 9 meters, but with a probability of impact of one 16 in 2095.

Aiming for To develop a dangerous earth asteroid defense system, the United States National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) will try to redirect an asteroid with a diameter of 150 meters.

Both agencies will attempt to reach the Didymos asteroid when performing the Double Asteroid Redirection Test (DART) on a ship. in December 2020 and will use one of its moons as its target: Didymoon about 11 million kilometers from Earth.

The kinetic impact technique is used to try to alter the trajectory of a hypothetical dangerous asteroid for Earth. To achieve this, the scientists plan to send a space probe to collide with the asteroid and change course, the ESA said.

The deviation of the celestial body is measured and analyzed to assess whether this method has potential in the event of a real threat. Didymoon was chosen as a test object because it is very small and does not pose a major threat.
