Kraken Catena
Crater chain on Triton
14°00′N 35°30′E / 14.000°N 35.500°E / 14.000; 35.500[1]
Kraken Catena is a pit chain (catena) and likely tectonic fault[2] on Triton, the largest natural satellite of Neptune. It, along with Set Catena, is located near and is aligned approximately radially from Leviathan Patera, a major cryovolcanic feature; as such, Kraken Catena may have played a role in rift-induced cryovolcanic activity in Leviathan Patera.[2][3] Several of Kraken Catena's pits have central steep-sided knobs, giving a moated appearance similar to the moated mountains found on Pluto's moon Charon and Uranus's moon Ariel.[3]
As with all other surface features of Triton, Kraken Catena was discovered when Voyager 2 visited the Neptune system on 25 August 1989. It is named after the Kraken of Norse mythology; the name was officially approved by the International Astronomical Union (IAU) in 1991. It is located at 14°N, 35.5°E, within Cipango Planum and Monad Regio.[1]
