Asteroid Bennu Could Be A 22nd Century Problem For Earth | Video

NASA's OSIRIS-REx mission will study the space rock that is 4 to 5 thousand times larger than the asteroid that exploded over the skies of Chelyabinsk in 2013. There is a small probability that it could hit Earth late in the 22nd century. NASA will study its orbit, composition and return a sample to Earth in 2023. -- Bring Some Asteroid To Earth - OSIRIS-Rex 2023 | Video:
