Ruach Planitia
Ruach Planitia is a roughly circular flat plain and probable cryovolcano, cryolava lake on Neptune's moon Triton (moon), Triton. It is located in Triton's northern hemisphere within Monad Regio and directly borders the cryovolcanic plains of Cipango Planum to the east and Tuonela Planitia to the west. Ruach Planitia, along with the other three Geology of Triton#Walled plains, walled plains of Triton, is one of the youngest and flattest features observed on the moon. Discovery and naming Ruach Planitia was discovered alongside Triton's other surface features by the ''Voyager 2'' spacecraft during its flyby (spaceflight), flyby of the Neptune system on 25 August 1989. The name Ruach Planitia was approved by the International Astronomical Union (IAU) in 1991; it is named after the Mythology in France, legendary French isle of Ruach (island), Ruach.

Voyager 2
''Voyager 2'' is a space probe launched by NASA on August 20, 1977, as a part of the Voyager program. It was launched on a trajectory towards the gas giants (Jupiter and Saturn) and enabled further encounters with the ice giants (Uranus and Neptune). The only spacecraft to have visited either of the ice giant planets, it was the List of artificial objects leaving the Solar System, third of five spacecraft to achieve Solar escape velocity, which allowed it to leave the Solar System#Farthest regions, Solar System. Launched 16 days before its twin ''Voyager 1'', the primary mission of the spacecraft was to study the outer planets and its extended mission is to study interstellar space beyond the Sun's heliosphere. ''Voyager 2'' successfully fulfilled its primary mission of visiting the Exploration of Jupiter, Jovian system in 1979, the Exploration of Saturn, Saturnian system in 1981, Exploration of Uranus, Uranian system in 1986, and the Exploration of Neptune, Neptunian system ...
