Suara.com – NASA previously announced that asteroid Bennu potentially dangerous to Earth and will pass through the planet in the 22nd century.
Latest data collected from spacecraft visits to asteroid Bennu, revealed that the rock has a very small chance of hitting Earth.
Experts used data from the Osiris-Rex mission, which studied and sampled Bennu, to better understand the asteroid’s future trajectory.
Reported from CNET, Friday (13/8/2021), a team of scientists found a small possibility that the 518 meter wide rock will have an impact on Earth in the future.

That probability is about 1 in 1,750 or 0.06 percent between 2021 and 2300.
Estimates generated before OSIRIS-REx arrived at Bennu, calculated the cumulative probability of a space rock impact between 2175 and 2199 at 1 in 2,700, much higher than the current probability.
According to Davide Farnocchia of NASA’s Center for Near-Earth Object Studies (CNEOS), there is no threat of a collision as long as Bennu passes close to Earth.
However, there is uncertainty about how some effects, such as Earth’s gravity, could alter the path of Bennu’s trajectory and make subsequent impacts more likely.
These findings indicate, at least Earth will be safe from the asteroid Bennu collision path until 2135.

Probably, there is nothing to worry about until 2300, although it is predicted that future scientists will observe the path of the asteroid in September 2182.
Specifically, NASA estimates that on September 24, 2182, Bennu has a 0.04 percent chance of impacting Earth.
However, scientists say there’s no need to worry too much about it because there’s still time to keep track of the asteroid’s movement.
