Triton is usually represented as a merman, with the upper body of a human and the tailed lower body of a fish. At some time during the Greek and Roman era, Triton(s) became a generic term for a merman (mermen) in art and literature. In English literature, Triton is portrayed as the messenger or herald for the god Poseidon.
Triton is only slightly larger than Pluto and is nearly identical in composition, which has led to the hypothesis that the two share a common origin. [ 27 ] This has been further supported in a 2024 study of the chemical composition of Pluto and Triton which suggests they originated in the same region of the outer Solar System before the latter ...
Other moons of Neptune are also named for Greek and Roman water gods, in keeping with Neptune's position as god of the sea: [16] either from Greek mythology, usually children of Poseidon, the Greek equivalent of Neptune (Triton, Proteus, Despina, Thalassa); lovers of Poseidon (Larissa); other mythological creatures related to Poseidon ...
Topography does not appear to strongly control the extent of Triton's volatile distribution (in strong contrast to Pluto's Sputnik Planitia ice sheet). However, the extent of Triton's polar caps may be significantly influenced by the internal heat flux from Triton's interior, with larger heat fluxes inducing greater asymmetry in the extent of ...
Many TNOs are often just assumed to have Pluto's density of 2.0 g/cm 3, but it is just as likely that they have a comet-like density of only 0.5 g/cm 3. [ 4 ] For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 ...

In ancient Greek religion and mythology, Pluto (Greek: Πλούτων, Ploutōn) was the ruler of the Greek underworld. The earlier name for the god was Hades , which became more common as the name of the underworld itself.
This is the primary reason it has a larger population than the other Neptunian resonances encountered in the Kuiper Belt. The cloud of low-inclination bodies beyond 40 AU is the cubewano family, while bodies with higher eccentricities (0.05 to 0.34) and semimajor axes close to the 3:2 Neptune resonance are primarily plutinos.
