EponymCaleuche, a Chilean legendary ghost ship

Caleuche Chasma is a Y-shaped chasma on Pluto's moon, Charon.[1] Caleuche Chasma is 400 km (250 mi) long. The feature was discovered using stereoscopic processing of New Horizons images. At approximately 13 km (8.1 mi) deep, it is the deepest known feature on the natural satellite,[2] and one of the deepest known canyons in the Solar System.

Naming

Caleuche Chasma got its official name from the IAU along with eleven other surface features of Charon on 11 April 2018[3] in response to a proposal by NASA's New Horizons team. It is named for the mythical Chilean ghost ship Caleuche. The designation was a part of the Our Pluto initiative by New Horizons, which invited the general public to suggest and vote for names for surface features in the Pluto system. Caleuche was included in the voting on 21 March 2015.[4] It did not make to the initial proposal, sent to the IAU by the New Horizons team on 7 July 2015[5] but was included later.

In 2019, composer and Royal Academy of Music professor David Gorton[6][7] wrote a composition for two cellos titled Caleuche Chasma[8]
