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 ...
The planet Neptune has 16 known moons, which are named for minor water deities and a water creature in Greek mythology. [ note 1 ] By far the largest of them is Triton , discovered by William Lassell on 10 October 1846, 17 days after the discovery of Neptune itself.
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.
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.

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 ...
Pluto's four small circumbinary moons orbit Pluto at two to four times the distance of Charon, ranging from Styx at 42,700 kilometres to Hydra at 64,800 kilometres from the barycenter of the system. They have nearly circular prograde orbits in the same orbital plane as Charon. All are much smaller than Charon.
All four, along with Titan, Triton, and Earth's Moon, are larger than any of the Solar System's dwarf planets. The largest, Ganymede, is the largest moon in the Solar System and surpasses the planet Mercury in size (though not mass). Callisto is only slightly smaller than Mercury in size; the smaller ones, Io and Europa, are about the size of ...
