NASA's Plan To Save Earth From Asteroid Bennu!

Asteroid Bennu was discovered in 1999. It's diameter is 500 meters and mass 78 billion kilograms. There is 1 in 2700 chance of Bennu hitting Earth between 2175-2199.

To learn more about these Asteroids NASA launched OSIRIS-REx in 2016. After traveling for 2 years and billions of kilometers OSIRIS-REx reached Bennu on 3 december 2018. We've already found water on Bennu. In 2020, OSIRIS-REx will take samples from Bennu and deliver them to Earth in 2023.
