Mordor Macula // is a large dark area about 475 km in diameter near the north pole of Charon, Pluto's largest moon. It is named after the black land in J.R.R. Tolkien's The Lord of the Rings trilogy, which it strongly resembles in shape. The name is not official; the discovery team has been using the name informally and may submit it to the IAU.
It is now known what Mordor Macula is made from. It is made from methane which travels from Pluto and lands on Charon. It may be frozen gases captured from Pluto's escaping atmosphere, a large impact basin, or both.
