This body contains a so-called "mountain in a moat" whose origin is unknown. This body's large system of northwest–southeast canyons includes Macross Chasma (KAZ-muh) and Serenity Chasma, in addition to Tardis Chasma, which bisects Gallifrey Macula. In 2016, scientists announced that a large dark area informally known as "Mordor" near the north pole of this body contains a cap composed of organic macromolecules called tholins, which are believed to have been formed by the reaction of compounds transferred to this body by its parent body, with which it is gravitationally locked. This moon is almost half the size of its parent body, and the two orbit their mutual barycenter, which was one reason that this moon's parent body was stripped of planet status. For 10 points, identify this largest moon of Pluto.
