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 composition of Bernini's Neptune and Triton consists of Neptune standing astride over Triton; Triton lies in sort of a "crouching" position; [a] the two figures mounted on a large half-shell, [14] [15] which serves as socle. [16] Neptune aims his trident seawards, [17] while Triton is blowing his conch. The conch was designed to spurt out ...
Triton was referred to as "trumpeter of Neptune (Neptuni tubicen)" in Cristoforo Landino (d. 1498)'s commentary on Virgil; [76] this phrasing later appeared in the gloss for "Triton" in Marius Nizolius's Thesaurus (1551), [77] and Konrad Gesner's book (1558). [78] Triton makes appearance in English literature as the messenger for the god ...
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 ...
In this scenario, Triton directly interacts with surrounding gas and dust around Neptune, inducing drag that bleeds energy from Triton's orbit. A close encounter with Neptune, where Triton's relative velocity is larger due to gravitational acceleration, is capable of directly capturing Triton from Solar orbit in a single pass.
Triton is massive enough to have achieved hydrostatic equilibrium and to retain a thin atmosphere capable of forming clouds and hazes. Inward of Triton are seven small regular satellites, all of which have prograde orbits in planes that lie close to Neptune's equatorial plane; some of these orbit among Neptune's rings. The largest of them is ...
Triton was discovered by William Lassell just 17 days after the discovery of Neptune itself. Unlike all other large planetary moons in the Solar System, Triton has a retrograde orbit, indicating that it was captured rather than forming in place; it was probably once a dwarf planet in the Kuiper belt.

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.
