Points to consider:
1. KBOs that were expelled by gravitational interactions (i.e, tides) may have experienced cryovolcanic activity and structural deformation (e.g., rifting).
2. KBOs that were expelled from the space between Saturn and Neptune may have different chemical compositions than indigenous KBOs that formed outside of the orbit of Neptune.
3. All KBOs have surface deposits containing organic compounds, amorphous carbon, and refractory compounds similar to the crusts of short-period comets.
4. Some KBOs may have a rocky core that formed by internal differentiation.
5. It may be possible in the future to land on a KBO and to cause it to collide with Mars thereby increasing the atmospheric pressure and changing the climate on that planet
