Will the Earth not be threatened by the coming decades?

The US Air Force Agency (NASA) said on September 29 that the number of large asteroids passing near the Earth, especially medium sized asteroids, could destroy an entire population. large, has diminished and the probability of major collisions between these asteroids and Earth is minimal.

These assessments are the result of the most accurate statistics of objects around the Sun, less than 195 million kilometers from the planet and relatively close to Earth's orbit.

According to Tim Spahr, director of the "Asteroid Center" at Harvard University's Astrophysics Center (USA), "the risk of a very large asteroid colliding with the Earth before we detect it and alarming about this collision, has dropped significantly. "

Currently, NASA has detected 93% of the largest 3,300 asteroids (at least 1km in diameter) near the Earth and a large number of asteroids equivalent to a small mountain has fallen from 1,000 to 981 asteroids, of which 911 asteroids have been discovered.

Meanwhile, the average number of asteroids also dropped sharply from 35,000 to 19,500.

According to NASA, the new observations of the WISE telescope have shown that no object will threaten the Earth in the coming decades.
