The objects in this region are classified by their resonance. Objects exhibiting 1:2 resonance are sometimes called twotinos while those with 2:3 resonance are referred to as Plutinos. This resonance corresponds with the end of the region at approximately 50 Astronomical Units.  The objects in this area are composed of frozen hydrocarbons, and it has been suggested that Triton, Neptune's largest moon, could be an object captured from it. FTP, identify this region beyond
