NASA is sending the OSIRIS-REx spacecraft to sample near-Earth Asteroid 1999 RQ36

Near-Earth Objects, or NEOs, cross our planet's orbit on a regular basis, but only a handful are large enough to pose a threat. One of these objects is asteroid 1999 RQ36, a "leftover" from the formation of our solar system four-and-a-half billion...
