Charon
Pluto's oversized companion in the Kuiper Belt/Moons
Charon is so large relative to Pluto that the two actually orbit a point in space between them, making them more of a double dwarf planet than a planet-moon pair. At 1,212 km in diameter, Charon is over half the size of Pluto itself. The New Horizons flyby in 2015 revealed a surprisingly complex surface with canyons, mountains, and a dark reddish polar cap informally dubbed Mordor.
