Triton is the largest natural satellite of the planet Neptune. It is the only moon of Neptune massive enough to be rounded under its own gravity and hosts a thin, hazy atmosphere. Triton orbits Neptune in a retrograde orbit—revolving in the opposite direction to the parent planet's rotation—the only large moon in the Solar System to do so.
An annotated picture of some of Neptune's many moons as captured by the James Webb Space Telescope. The bright blue diffraction star is Triton, Neptune's largest moon; while Hippocamp, its smallest regular moon, is too small to be seen. The planet Neptune has 16 known moons, which are named for minor water deities and a water creature in Greek ...
The climate of Triton encompasses the atmospheric dynamics, weather, and long-term atmospheric trends of Neptune's moon Triton. The atmosphere of Triton is rather thin, with a surface pressure of only 1.4 Pa (1.38 × 10 −5 atm) at the time of Voyager 2 ' s flyby, [1]: 873 but heavily variable. Despite its low surface pressure, it still drives ...
Trident is a proposed NASA mission that is to further study Neptune's moon Triton. The proposed launch date of Trident is set for October 2025, arriving at the Neptune system by 2038. Triton is a probable ocean world of very high priority because of the glimpses of activity shown from the Voyager 2 flyby.
An annotated picture of Neptune's many moons as captured by the James Webb Space Telescope. The bright blue diffraction star is Triton, Neptune's largest moon. Neptune has 16 known moons. [155] Triton is the largest Neptunian moon, accounting for more than 99.5% of the mass in orbit around Neptune, [i] and is the only one massive enough to be ...
Along with its bright rings, the Webb observatory spied Neptune's fainter dust bands and seven of the planet's 14 known moons. The last time Neptune's rings were seen in detail was during a flyby ...
The geology of Triton encompasses the physical characteristics of the surface, internal structure, and geological history of Neptune's largest moon Triton. With a mean density of 2.061 g/cm 3, [1] Triton is roughly 15-35% water ice by mass; Triton is a differentiated body, with an icy solid crust atop a probable subsurface ocean and a rocky core.
Triton, Neptune's largest moon, has a tenuous nitrogen atmosphere with small amounts of methane. Tritonian atmospheric pressure is about 1 Pa . The surface temperature is at least 35.6 K, with the nitrogen atmosphere in equilibrium with nitrogen ice on Triton's surface.
