Asteroids will destroy civilization

NASA's OSIRIS-REx spacecraft collected information about the
asteroid Bennu from December 2018 to May 2021. This asteroid
now ranks second in the list of the most dangerous asteroids for
our planet. Therefore, scientists have calculated its orbit up to
2300. Data from OSIRIS-REx, NASA's Deep Space Network and
computer models have allowed scientists to reduce the uncertainty
of Bennu's orbit by a factor of 20. Now the chances of hitting the
Earth are estimated to about 1 in 1750, or 0.057%. In 2135, Bennu
will approach the Earth at a distance equal to about half the distance
from our planet to the Moon. This will change the trajectory of the
asteroid. Another approach will take place on September 24, 2182,
and scientists again do not exclude that the Earth will have an impact
on the asteroid in the area of ??the gravitational "keyhole".
The new study adjusted for many variables to predict Bennu's future
trajectory, including the masses of 343 known asteroids. Even the
possible impact of the OSIRIS-REx spacecraft at the time it took soil
samples from the asteroid on October 20, 2020 was taken into account.
OSIRIS-REx with samples from the asteroid remained in the vicinity
of Bennu until May 10. The mission will deliver a sample of the
asteroid to Earth on September 24, 2023. 
But the most dangerous known for Earth is the 1.3-kilometer near-Earth
asteroid from the Apollo 29075 group (1950 DA). The next rapprochement
of this killer with our planet will occur in 2032 and it could be fatal for
civilization.
