NASA has been keeping an eye on the Bennu asteroid for quite some time, and it’s now calculating the chances for the space rock to get into collision with our planet someday. Bennu measures about a third of a mile in width, meaning the equivalent of about three city blocks. Such size wouldn’t make the asteroid pose a threat to the existence of life on Earth, but still, you wouldn’t want such a space rock landing anywhere near your household or town.
According to WEAU NEWS, the famous NASA space agency claims that the Bennu asteroid has a chance to hit our planet in the next century. In other words, unless you’re somehow planning to live for more than 150 years, you don’t have to worry.
The Bennu asteroid could hit Earth in 2182
NASA scientists believe that there is a chance for Bennu to smash into our planet more than 150 years from now – in 2182, to be more precise. At the same time, astronomers believe that Bennu will make a close flyby of Earth much earlier, in 2135. However, the chance for the space rock to collide with Earth is “extremely small,” which should mean that we don’t have to worry about our descendants who will live in those times.
NASA explained in a statement:
During the flyby, there is an extremely small chance that Bennu will pass through a “gravitational keyhole” – a region of space that would set it on just the right path to impact Earth, late in the 22nd century.
NASA is usually on the lookout for asteroids that could pose a threat to life on Earth someday, but even despite its highly advanced gear, some asteroids could arrive unnoticed. One of the unwanted scenarios is when an asteroid comes from the direction of the Sun – in that case, astronomers can’t detect it.
