A milestone of sorts was reached this week as NASA announced that the New Horizons’ spacecraft has sent back roughly half of the data it captured during its flyby of Pluto in July 2015.

How likely is it that Pluto proves to be the most interesting or important object in a region which may contain as many as 35,000 objects with a diameter of 60 miles or more?
