In October 2020 , a van-sized robotic spacecraft briefly touched down on the surface of Bennu , a 525-meter -wide asteroid 320 million kilometers from Earth .

Asteroid Bennu was targeted for the OSIRIS -REx mission because remote sensing observations from Earth indicated it as a B-type asteroid.

Asteroids are fragmentary remnants of pre-existing parent bodies that have since been destroyed by collisions with other objects.
