In which year was the moon, on which the volcanic feature Reiden Patera is located, discovered ?
Reiden Patera Reiden Patera is a volcanic feature on Jupiter's moon Io. It was first detected by the "Galileo" SSI Team during the spacecraft Galileo's first orbit around Jupiter, initially detected as a hotspot. It was once thought that the activity there had stopped or waned below the limits of the spacecraft's Solid State Imager or Near-Infrared Mapping Spectrometer. However, it was noticed in 2002 that Reiden Patera has darkened considerably since the 24th orbit of "Galileo". It has been spouting bright red pyroclastic deposits of its own. It is located at and is 70 kilometers in diameter. It is named after a Japanese thunder god ("Raijin" in current English nomenclature). Asha Patera can be found to the east, and Kami-Nari Patera can be found to the north.
Moons of Neptune Neptune has 14 known moons, which are named for minor water deities in Greek mythology. By far the largest of them is Triton, discovered by William Lassell on October 10, 1846, just 17 days after the discovery of Neptune itself; over a century passed before the discovery of the second natural satellite, Nereid. Neptune's Neso, which has an orbital period of about 26 Julian years, orbits further from its planet than any other moon in the Solar System.
