Next century, an asteroid called Bennu could fly between the moon and Earth, possibly threatening life on Earth. So of course, NASA wants to study it.
The asteroid was first discovered in 1999 and crosses Earth's orbit every six years.
To study Bennu, NASA plans on launching a probe in September — called OSIRIS-REx — which should arrive at the asteroid in 2018.
