Set Catena
Set Catena is a pit chain (''catena'') and likely tectonic fault located on Triton, the largest natural satellite of Neptune. It, along with Kraken Catena, is located near Leviathan Patera, a major cryovolcanic feature; as such, Set Catena may have played a role in rift-induced cryovolcanic activity in Leviathan Patera. Set Catena extends radially northwards from Leviathan Patera, terminating at another irregularly-shaped walled depression. Set Catena consists of semi-regularly spaced pits roughly separated from each other, with each pit being on average and up to deep. The pits may have formed from collapse or from explosive cryovolcanic eruptions, and may have been subsequently expanded by mass wasting processes. Set Catena may be a northeastern extension of Raz Fossae, a similar fault system southwest of Leviathan Patera. As with all other surface features of Triton, Set Catena was discovered when ''Voyager 2'' visited the Neptune system on 25 August 1989. It is named ...

Kraken Catena
Kraken Catena is a crater chain, pit chain (''catena'') and likely Fault (geology), tectonic fault on Triton (moon), 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 cryovolcano, cryovolcanic feature; as such, Kraken Catena may have played a role in rift-induced cryovolcanic activity in Leviathan Patera. 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 (moon), Charon and Uranus's moon Ariel (moon), Ariel. 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. See also * List of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
