So far, only a single spacecraft has ever visited Images show that Triton's surface, which is mostly made up of rock and nitrogen ice, has cratered and smooth regions existing side by side. These smooth areas are the result of plumes of dust and nitrogen gas that erupt out of the moon's crust, and then get gently blown around by Triton's tenuous atmosphere. It's not clear, however, how dangerous those geysers would be to anyone standing next to them. [ The surface of Neptune's moon Triton is so cold, the ground is made of frozen nitrogen. (Image credit: By Karl Tate, Infographics Artist) "We poorly understand this plume activity," Adam Masters, a space physicist at Imperial College London in the U.K., told Space.com. "But I would err on the side of caution and not want to be standing on the region where the plume erupts." As Neptune makes its 165-year-long trip around the sun, the polar regions of Triton take turns bathing in the sun for some 80 years at a time. The sunlight results in If you lived on Triton, you wouldn't get to enjoy any seasonal effects to temperature. With an average temperature of minus 391 degrees Fahrenheit (minus 235 Celsius), Triton is the coldest- known object in the solar system. Interestingly, Triton didn't form along with its parent planet, and was likely an If you lived in a region on the moon that gets both night and day (a day on Triton is almost six Earth days), you would see the sun— which would be just a dot in the sky— rise in the west a...

Neptune and its moons. Credit: NASA Neptune, that icy gas giant that is the eight planet from our Sun, was discovered in 1846 by two astronomers – Urbain Le Verrier and Johann Galle. In keeping with the convention of planetary nomenclature, Neptune was named after the Roman god of the sea (the equivalent to the Greek Poseidon). And just seventeen days after it was discovered, astronomers began to notice that it too had a system of moons. Initially, only Triton – Neptune's largest moon – could be observed. But by the mid-20th century and after, thanks to improvements in ground-based telescopes and the development of robotic space probes, many more moons would be discovered. Neptune now has 14 recognized satellites, and in honor of of their parent planet, all are named for minor water deities in Greek mythology. Discovery and Naming: Triton, being the largest and most massive of Neptune's moons, was the first to be discovered. It was observed by William Lassell on October 10th, 1846, just seventeen days after Neptune was discovered. It would be almost a century before any other moons would be discovered. The first was Nereid, Neptune's second largest and most massive moon, which was discovered on May 1st, 1949, by Gerard P. Kuiper (for whom the Kuiper Belt is named) using photographic plates from the McDonald Observatory in Fort Davis, Texas. The third moon, later named Larissa, was first observed by Harold J. Reitsema, William B. Hubbard, Larry A. Lebofsky and David J. Thol...

In a thrilling development that propels Saturn back to the forefront of the Solar System's "moon race," an international team of astronomers, including researchers from the © Provided by Earth Saturn's latest additions not only reclaim its title for the most known moons, surpassing Jupiter's 95, but also make Load Error Dr. Edward Ashton initiated the research project at UBC and is currently a postdoctoral fellow at Taiwan's Academia Sinica Institute of Astronomy and Astrophysics. "Connecting the various appearances of these moons in our data to a viable orbit feels like playing the kid's game Dot-to-Dot. It's akin to playing about 100 different games on the same page, not knowing which dot belongs to which puzzle," said Dr. Ashton. How the discovery was made For the past two decades, astronomers have been probing Saturn's surroundings with heightened sensitivity in search of moons. In their latest quest, Ashton's team employed a technique known as "shift and stack," a first in the realm of Saturn moon searches. The method, previously used for moon explorations around The team relied on data collected by the Ashton's team includes UBC professor Dr. Brett Gladman, Dr. Mike Alexandersen from the Harvard Smithsonian Centre for Astrophysics, Dr. Jean-Marc Petit from Observatoire de Besancon, and Matthew Beaudoin from UBC. Tedious work and long hours The initial search for these moons was conducted in 2019, when Ashton and Beaudoin, then students at UBC, meticulously scrutinize...

Planets form from a circumstellar disc of dust and gas that surrounds a young star. This disc circles the star in one direction, and thus most planets and their moons orbit in this same direction. These orbits are known as prograde, and a rogue object that orbits backward is said to be in a retrograde orbit. The retrograde orbit of Triton means that it most likely did not form around The early solar system was a place of dynamic violence, with many bodies changing orbits and crashing into each other. Triton likely originated in the Directly after capture, the moon would have been in a highly elliptical, eccentric orbit. This type of orbit would have raised large tides on the moon, and the friction of these tides would have caused energy to be lost. The energy loss is converted into heat within the moon, and this heat may have melted some of the icy interior and formed an ocean beneath Triton's ice shell. The energy loss from tides is also responsible for gradually changing Triton’s orbit from an ellipse to a circle, researchers say. Heating the interior Friction from tides is not the only source of heat within a terrestrial body; there is also radiogenic heating. This is heat produced by the decay of radioactive isotopes within a moon or planet, and this process can create heat for billions of years. Radiogenic heating contributes several times more heat to Triton’s interior than tidal heating; however, this heat alone is not sufficient to keep the But tidal dissipation ca...

The planets of the outer Solar System are known for being strange, as are their many moons. This is especially true of Triton, Neptune’s largest moon. In addition to being the seventh-largest moon in the Solar System, it is also the only major moon that has a retrograde orbit – i.e. it revolves in the direction opposite to the planet’s rotation. This suggests that Triton did not form in orbit around Neptune, but is a cosmic visitor that passed by one day and decided to stay. And like most moons in the outer Solar System, Triton is believed to be composed of an icy surface and a rocky core. But unlike most Solar moons, Triton is one of the few that is known to be geologically active. This results in Discovery and Naming: Triton was discovered by British astronomer William Lassell on October 10th, 1846, just 17 days after the discovery of Neptune by German astronomer Johann Gottfried Galle. After learning about the discovery, John Herschel – the son of famed English astronomer William Herschel, who discovered many of Saturn’s and Uranus’ moons – wrote to Lassell and recommended he observe Neptune to see if it had any moons as well.

The moon Triton Triton is the largest of Neptune’s moons. Triton has a diameter of roughly 2,700 kilometers. It rotates and orbits Neptune every 5.9 Earth days. And it is the seventh largest moon in solar system. While Neptune has a dozen other moons, Triton’s mass is literally twenty times greater than the rest of the moons put together. Triton is about two thirds the size of Earth’s moon. Triton is unique for being a large moon with a retrograde orbit and its exotic early history. History of Triton Triton may have originated in the Kuiper Belt, a region beyond Neptune filled with rocky bodies ranging from tiny asteroids to the Plutoids. The Plutoids include the dwarf planet Pluto and similarly sized objects like Sedna and Makemake. This theory is further supported by the melted and reformed surface of Triton, giving it a relatively smooth surface. This theory is also backed up by the fact that Pluto itself crosses Neptune’s orbit; this means that Triton could have been a similar dwarf planet that crossed Neptune’s orbit but was captured by its gravity. Triton was discovered in 1846. William Lassell discovered Triton almost three weeks after Neptune itself was discovered by German astronomers. Triton is named for a son of the Greek god Poseidon or Neptune. Triton's odd orbit Triton orbits Neptune every 141 hours. Triton also rotates once per orbit, so that the same side always faces Neptune. Triton is unique because it is the only large moon that has a retrograde orbit, a...
