NASA: Asteroid Bennu could fall to Earth in 2135

NASA may not be able to stop the Bennu Asteroid because its "unstable" design means it could fall to Earth in 2135, scientists warned.

The giant asteroid, named by scientists as one of the most potentially dangerous asteroids, is estimated to be the size of the Empire State Building.

The enormous cosmic universe has the potential to release 1,200 megatonic energy in collision - 80,000 times that of the Hiroshima bomb.

Members of a US national defense team have published a research warning about the "terrible" consequences of asteroid collisions with Earth.
