Until the discovery of the second moon Nereid in 1949, Triton was commonly known as simply "the satellite of Neptune. Featuring some of the most popular crossword puzzles, uses the knowledge of experts in history, anthropology, and science combined to provide you solutions when you cannot seem to guess the word. Triton is named after the son of Poseidon (the Greek god comparable to the Roman Neptune). The clue ' One of Neptune's moons ' was last spotted by us at the New York Times Crossword on Septem. During its 1989 flyby, Voyager 2 also found Triton has active geysers, making it one of the few geologically active moons in our solar system. NASA's Voyager 2―the only spacecraft to fly past Neptune and Triton―found surface temperatures of -391degrees Fahrenheit (-235 degrees Celsius). It is so cold that most of Triton's nitrogen is condensed as frost, giving its surface an icy sheen that reflects 70 percent of the sunlight that hits it. Triton is one of the coolest objects in our solar system. Triton, Io and Venus are the only bodies in the solar system besides Earth that are known to be volcanically active at the present time. This atmosphere most likely originates from Triton's volcanic activity, which is driven by seasonal heating by the Sun. Triton's thin atmosphere is composed mainly of nitrogen with small amounts of methane. Facebook gives people the power to share and makes the world more open and connected. By far the largest of them is Triton, discovered by William Lassell on October 10, 1846, 17 days after the discovery of Neptune itself over a century passed before the discovery of the second natural satellite, Nereid. This implies that Triton contains more rock in its interior than the icy satellites of Saturn and Uranus. Join Facebook to connect with Neptunes Moons and others you may know. The planet Neptune has 14 known moons, which are named for minor water deities in Greek mythology. This is a higher density than that measured for almost any other satellite of an outer planet. In case there is more than one answer to this clue it means it has appeared twice, each time with a different answer. Triton is Neptunes only large moon with a diameter of 2,704 km. Triton has a density about twice that of water. Neptune has 13 known moons, though most are small and orbit closer to Neptune than its rings. Triton consists of a crust of frozen nitrogen over an icy mantle believed to cover a core of rock and metal. How Many Moons Does Neptune Have Despite its distance from the sun and frosty nature, Neptune is far from alone at the outskirts of the solar system. Spacecraft images show the moon has a sparsely cratered surface with smooth volcanic plains, mounds and round pits formed by icy lava flows. The clue ' One of Neptunes moons ' was last spotted by us at the New York Times Crossword on Septem. Triton has a diameter of 1,680 miles (2,700 kilometers).

There is an excellent resource for more information about Neptune's Moons on the NASA website. Triton is much larger than any of the planets other moons. Particularly for the five outer moons, some of this information is conjectural, and subject to change. It also has rings, but its rings are different from Saturns. Triton is so much larger than the other moons that it makes up about 99.7% of the total mass of all the moons.īelow, a table lists the known moons, with information about their orbits and diameters. Unfortunately, for Triton, its orbit is decaying, and in the relatively near future, perhaps several million years, it will disintegrate, and could form a new, more distinct ring system. Triton is in a synchronous orbit around Neptune, meaning that, like our own Moon, the same side faces Neptune. It is the only large moon in the Solar System that has a Retrograde Orbit. It was once, possibly, a Kuiper Belt Object as it is very similar to Pluto. This leads astronomers to believe that it was captured long in the past, as virtually all natural satellites, formed along with their parent body, orbit in Prograde Orbits. From our Earthly vantage point, Naiad only strays about arc second from the disk of Neptune, a. Triton, the largest at more than 2,700 km in diameter, and the one first discovered soon after Neptune itself on October 10th 1846 by the English astronomer William Lassell, orbits in a Retrograde Orbit, in the opposite direction to most of the other moons. Neptune itself is about 49,000 kilometres in diameter, and only appears 2.3 in size from Earth. Nereid, a small irregular moon of Neptune, orbits at an average distance of more than 15. Neptune has 14 identified moons, as at September 2013, named for minor water deities in Greek mythology. One of Neptunes moons is an exception to this, however: Triton.
