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.
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 ...
Triton, the largest moon of the ice giant planet Neptune, is hypothesized to have been captured from heliocentric orbit. Triton is unusual as it is the only known large moon on a retrograde, highly-inclined orbit; that is
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.
The next-largest satellite in the Solar System suspected to be captured, Saturn's moon Phoebe, has only 0.03% of Triton's mass. The capture of Triton, probably occurring some time after Neptune formed a satellite system, was a catastrophic event for Neptune's original satellites, disrupting their orbits so that they collided to form a rubble disc.
Triton's southern polar cap and dark plume streaks. 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 ...
The largest moon of the planet Neptune has been given the name Triton, as Neptune is the Roman equivalent of Poseidon. A family of large sea snails, the shells of some of which have been used as trumpets since antiquity, are commonly known as "tritons", see Triton (gastropod) .
Leviathan Patera is a major cryovolcanic caldera on Neptune's largest moon Triton. [3] Discovered by the Voyager 2 spacecraft in 1989, Leviathan Patera is located in Monad Regio and within Cipango Planum's western regions.
