(Bennu, 1999 RQ36)
(near-Earth asteroid that is the target of a planned sample-return mission)
101955 Bennu (provisional designation: 1999 RQ36)
is a near-Earth asteroid discovered in 1999.
The mission in planning, OSIRIS-REx, aims to visit
it, remove a sample and return to Earth.
Its diameter is on the order of 500 meters and its orbit
is sufficiently close to Earth's that a future impact is possible.
