Triton
/ˈtraɪtən/noun
The son of Poseidon, a merman who calms the waves with a conch, and the largest moon of Neptune.
The Greek roots
Literally: “the sea god, Poseidon's herald”
The story of the word
William Lassell found the moon seventeen days after Neptune itself was identified in 1846, but it went unnamed for decades; Flammarion proposed Triton in 1880 and the name only became standard in the twentieth century. The moon orbits backwards, which means it was captured rather than formed there, and Voyager 2 photographed nitrogen geysers on it in 1989. The god's own name is old and its origin is unsettled, though it clearly belongs with Amphitrite.
