From Ancient Greek Χάρων (Khárōn). The name of the moon was coined by American astronomer James W. Christy in 1978, in reference to a fictional moon of Pluto in a novel by Edmond Hamilton but also influenced by its similarity to Char, a pet name for Charlene, his wife's name — hence the alternative American pronunciation, which is used at NASA.

Plutonian

en-adj

Plutonian (comparative more Plutonian, superlative most Plutonian)

more Plutonian (comparative)
most Plutonian (superlative)

The adjective is derived from Latin Plūtōnius (“of or relating to Pluto, Greek and Roman god of the underworld”) + -an (suffix forming adjectives). Plūtōnius is from Ancient Greek Πλουτώνιος (Ploutṓnios, “of or relating to Pluto”), from Πλούτων (Ploútōn, “Pluto”) (from πλοῦτος (ploûtos, “riches, wealth”) (ultimately from Proto-Indo-European *plew- (“to fly; to flow; to run”)) + -ων (-ōn)) + -ιος (-ios, suffix forming adjectives). The English word is cognate with Middle French plutonien (modern French plutonien). The noun is derived from the adjective.

plutonien

Cotopaxi is striking not only because it looks like a science fiction conception of another planet; it also is the least realistic among [Frederic Edwin] Church's paintings of the area. […] Below the fiery sun is a lake with a barren shore. As such, the sun hangs over a Plutonian landscape.

Plutonian

From Pluto (“dwarf planet in the Solar System”) + -n- + -ian (suffix forming adjectives meaning ‘from, related to, or like’, or nouns meaning ‘one belonging to, relating to, or like’), probably influenced by Plutonian (“of or relating to Pluto, Greek and Roman god of the underworld”) (see etymology 1).

Another and perhaps more Plutonian view of this would be that David's bondage to his mother and the codes of behaviour which she set for him had extended throughout his life, in both profes[s]ional and personal spheres; and that bondage now had an opportunity of loosening, with all the attendant consequences.

The notion of toxicity is a useful one in our effort to understand the further implications of Pluto in the USA chart. [...] Factor in what we have learned about the second house and we get another meaning of waste, related but distinctly more Plutonian: debris that poses an elimination problem once its value has been used up.

Burl studied the captured Plutonian hand weapons, and was pleased to have one of the Neptunian soldiers pick one up and demonstrate how it was fired. It had apparently simpler controls than most Plutonian products, for it easily blazed forth a bolt of electronic fire that blasted a tall, crystalline tree to shards.

Roure did not carry his work to completion. He derived only four intermediate orbits of Pluto for the combinations of Pluto and the four outer planets, and determined the inequalities in the Plutonian motion under the effect of Neptune which are dependent on the first degree of Plutonian eccentricity and inclination.

[Gerard] Kuiper (1944) searched for spectroscopic evidence of an atmosphere around Pluto as part of the same program that discovered CH₄ on Titan. Because of the difficulty of observing an object as faint as Pluto, no useful results were obtained; however, Kuiper presented arguments in favor of a Plutonian atmosphere based on the stability of the atmosphere against loss to space.

Plutonian

If you are a Plutonian and some of these traits emphatically do not fit you, just let them go and take what is helpful and descriptive of you personally. What will be given is a composite picture, based on working with a great many Plutonians over the years. Plutonians who are negatively inclined are often very guarded and rigid, afraid to let others get close. [...] There are Plutonians who operate predominantly on the positive level—healing, transforming, transmuting themselves and those around them.

(astrology) A person under the astrological influence of Pluto, formerly regarded as a planet.

The Plutonians, who are almost extinct, once held a superscience that they have largely lost. Early Plutonian visits to Earth survived in folk memory as the devil, since Plutonians are gigantic, with horns, hooves, and tail.
