   Explanation: Put on your red/blue glasses and float next to asteroid
   [7]101955 Bennu. Shaped like a spinning toy top [8]with boulders
   littering its rough surface, the tiny Solar System world is about
   [9]one Empire State Building (less than 500 meters) across. Frames used
   to construct this 3D anaglyph were taken by PolyCam on the
   [10]OSIRIS_REx spacecraft on December 3, 2018 from a distance of about
   80 kilometers. [11]With a sample from the asteroid's [12]rocky surface
   on board, OSIRIS_REx departed Bennu's vicinity this May and is now
   enroute to planet Earth. The robotic spacecraft is scheduled to return
   the sample to Earth [13]in September 2023.
