(Southwest Research Institute)
Pluto’s giant moon Charon shows pervasive extensional tectonism and locally extensive cryovolcanic resurfacing, both dating from early in solar system history. Its color and surface composition, dominated by H$_2$O ice plus NH$_3$ hydrate, is remarkably uniform apart from a thin deposit of dark red material near the north pole which may be due to cold-trapping and radiolysis of hydrocarbons escaping from Pluto. Pluto’s four small moons, probably created from the debris of the giant collision that also formed Charon, exhibit complex rotational behavior unlike any seen elsewhere in the solar system.
Unlike many icy satellites of the giant planets, neither Pluto nor Charon is likely to have experienced tidal heating during the period when observable landforms were created. Both objects therefore provide an important testbed for models of internal heating of icy worlds throughout the outer solar system.
