NASA officially announced on Wednesday that an asteroid named “Bennu” is expected to approach the Earth sometime in the 2100s. Its size is about the size of the Empire State Building in New York. Scientists revealed that its probability of hitting the Earth is 1 in 1,750. .
The NASA OSIRIS-REx spacecraft has been monitoring Bennu’s trajectory for the past two years. However, during the period from 2135 to 2182, its trajectory is unpredictable, with an error of approximately 125,000 miles. If its trajectory overlaps the Earth, Impacting the earth may cause a crater more than 100 times its actual size, and the possible damage must be taken seriously.
However, as NASA predicted, the probability of this incident is extremely low. At the same time, to avoid disasters, NASA will also launch a new defense strategy “Double Asteroid Redirect Test” against another asteroid “Didymos” next year. Interested readers may wish to pay more attention. .
