The New Horizons mission is set to explore part of this region, which includes objects with too low a density to become planets.
The purported largest object in this region may actually lie in the Scattered Disc with which it shares a toroid area. This region has a namesake cliff at its 1:2 resonance, and certain objects in this region that are not resonant are called cubewanos. The New Horizons mission is set to explore part of this region, which includes objects with too low a density to become planets. It was described in 1943 by a man who sometimes names it, Kenneth Edgeworth, and its occupants include the Centaurs, Pluto, and Eris. For 10 points, name this region home to short-period comets and trans-Neptunian objects, forming its namesake "belt."
