   Explanation: Last Wednesday the [7]voyaging Lucy spacecraft
   [8]encountered its first asteroid, [9]152830 Dinkinesh, and discovered
   the inner-main belt asteroid has a moon. From a distance of just over
   400 kilometers, Lucy's Long-Range Reconnaissance Imager [10]captured
   this close-up of the binary system during a flyby at 4.5 kilometer per
   second or around 10,000 miles per hour. [11]A marvelous world,
   Dinkinesh itself is small, less than 800 meters (about 0.5 miles)
   across at its widest. Its satellite is seen from the spacecraft's
   perspective to emerge from behind the primary asteroid. The asteroid
   moon is estimated to be only about 220 meters wide.
