=== Symbol === Once named, Pluto's [[planetary symbol]] {{angbr|[[File:Pluto monogram (fixed width).svg|20px|♇|link=wikt:♇]]}} was then created as a [[monogram]] of the letters "PL".<ref name="JPL/NASA Pluto's Symbol" /> This symbol is rarely used in astronomy anymore,{{efn|name = PL |For example, {{angbr|♇}} (in [[Unicode]]: {{unichar|2647|PLUTO}}) occurs in a table of the planets identified by their symbols in a 2004 article written before the 2006 IAU definition,<ref>{{cite book |editor=John Lewis |date=2004 |title=Physics and chemistry of the solar system |edition= 2 |page=64 |publisher=Elsevier}}</ref> but not in a graph of planets, dwarf planets and moons from 2016, where only the eight IAU planets are identified by their symbols.<ref>{{cite journal |author1= Jingjing Chen |author2= David Kipping |year=2017 |title= Probabilistic Forecasting of the Masses and Radii of Other Worlds |journal= The Astrophysical Journal |volume= 834 |issue= 17 |page= 8 |publisher= The American Astronomical Society|doi= 10.3847/1538-4357/834/1/17 |arxiv= 1603.08614 |bibcode= 2017ApJ...834...17C |s2cid= 119114880 |doi-access= free }}</ref> (Planetary symbols in general are uncommon in astronomy, and are discouraged by the IAU.)<ref name="iau_1989">{{cite book|date=1989|language=en|page=27|title=The IAU Style Manual|url=http://www.iau.org/static/publications/stylemanual1989.pdf|access-date=January 29, 2022|archive-date=July 26, 2011|archive-url=https://web.archive.org/web/20110726170213/http://www.iau.org/static/publications/stylemanual1989.pdf|url-status=live}}</ref>}} though it is still common in astrology. However, the most common [[astrological symbol]] for Pluto, occasionally used in astronomy as well, is an orb (possibly representing Pluto's invisibility cap) over Pluto's [[bident]] {{angbr|[[File:Pluto symbol (large orb, fixed width).svg|20px|⯓|link=wikt:⯓]]}}, which dates to the early 1930s.<ref>Dane Rudhyar (1936) ''The Astrology of Personality'', credits it to Paul Clancy Publications, founded in 1933.</ref>{{efn|name = bident|The bident symbol ({{Unichar|2BD3|PLUTO FORM TWO}}) has seen some astronomical use as well since the IAU decision on dwarf planets, for example in a public-education poster on dwarf planets published by the NASA/JPL ''Dawn'' mission in 2015, in which each of the five dwarf planets announced by the IAU receives a symbol.<ref>NASA/JPL, [https://www.jpl.nasa.gov/infographics/what-is-a-dwarf-planet What is a Dwarf Planet?] {{Webarchive|url=https://web.archive.org/web/20211208181916/https://www.jpl.nasa.gov/infographics/what-is-a-dwarf-planet |date=December 8, 2021 }} 2015 Apr 22</ref> There are in addition several other symbols for Pluto found in astrological sources,<ref>Fred Gettings (1981) ''Dictionary of Occult, Hermetic and Alchemical Sigils.''

In 1930, [[Walt Disney]] was apparently inspired by it when he introduced for [[Mickey Mouse]] a canine companion named [[Pluto (Disney)|Pluto]], although [[Disney]] animator [[Ben Sharpsteen]] could not confirm why the name was given.<ref name="Heinrichs2006" /> In 1941, [[Glenn T. Seaborg]] named the newly created [[Chemical element|element]] [[plutonium]] after Pluto, in keeping with the tradition of naming elements after newly discovered planets, following [[uranium]], which was named after Uranus, and [[neptunium]], which was named after Neptune.<ref name="ClarkHobart2000" /> Most languages use the name "Pluto" in various transliterations.{{efn|The equivalence is less close in languages whose [[phonology]] differs widely from [[Ancient Greek phonology|Greek's]], such as [[Somali language|Somali]] ''Buluuto'' and [[Navajo language|Navajo]] ''Tłóotoo''.}} In Japanese, [[Houei Nojiri]] suggested the [[calque]] {{nihongo3|"Star of the King (God) of the Underworld"|冥王星|Meiōsei}}, and this was borrowed into Chinese and Korean. Some [[languages of India]] use the name Pluto, but others, such as [[Hindi]], use the name of ''[[Yama]]'', the God of Death in Hinduism.<ref name="nineplan" /> [[Polynesian languages]] also tend to use the indigenous god of the underworld, as in [[Māori language|Māori]] ''[[Whiro]]''.<ref name="nineplan" /> Vietnamese might be expected to follow Chinese, but does not because the [[Sino-Vietnamese vocabulary|Sino-Vietnamese]] word 冥 ''minh'' "dark" is homophonous with 明 ''minh'' "bright". Vietnamese instead uses Yama, which is also a Buddhist deity, in the form of ''Sao Diêm Vương'' 星閻王 "Yama's Star", derived from Chinese 閻王 ''[[Yama (Buddhism)|Yán Wáng / Yìhm Wòhng]]'' "King Yama".<ref name="nineplan" /><ref name="RenshawIhara2000" /><ref name="Bathrobe" />
