Meng-pʽo Macula

Meng-po Macula is the easternmost of the "Brass Knuckles", a series of equatorial dark regions on Pluto. Meng-po straddles the zero meridian, directly under Pluto's tidally locked moon Charon and just west of the tail of the "Whale", Belton Regio. It is named after Meng Po, the Chinese underworld deity of forgetfulness.
