Il primo termine fu rigettato durante l'Assemblea, in parte perché già utilizzato in <a href="/wiki/Geologia" title="Geologia">geologia</a> per indicare una tipologia di <a href="/wiki/Rocce_intrusive" class="mw-redirect" title="Rocce intrusive">rocce intrusive</a>, i <a href="/wiki/Plutone_(geologia)" title="Plutone (geologia)">plutoni</a> appunto; il secondo non ottenne la maggioranza dei voti necessaria alla sua approvazione. </p><p>Anche l'elenco delle caratteristiche che sarebbero dovute essere attribuite alla nuova categoria hanno subito alcune variazioni. Quando fu inizialmente proposta, la categoria dei “plutoni” avrebbe dovuto raccogliere i pianeti aventi un periodo di rotazione intorno al Sole superiore a 200 <a href="/wiki/Anno_giuliano" title="Anno giuliano">anni</a> ed un'orbita con un'inclinazione ed un'eccentricità superiori a quelle dei pianeti tradizionali<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>. Quando, nel corso dell'Assemblea, fu avanzata la contro-proposta di stralciare Plutone dal rango planetario, tale categoria di oggetti simili a Plutone fu applicata ai pianeti nani che rispettano i requisiti di essere transnettuniani e "come Plutone" in termini di periodo, inclinazione ed eccentricità orbitali. All'ultimo, la risoluzione finale lasciò la definizione formale della nuova categoria, come ad esempio la scelta del nome, ad un successivo momento. </p><p>Successivamente alla Assemblea Generale dell'Unione Astronomica Internazionale, il termine "plutoide" è stato proposto dai membri del Committee on Small Body Nomenclature ("Comitato per la nomenclatura dei corpi minori", CSBN) - ed accettato dal Gruppo di lavoro per la nomenclatura dei sistemi planetari ed infine approvato dal Comitato esecutivo della IAU durante l'incontro svoltosi ad <a href="/wiki/Oslo" title="Oslo">Oslo</a> l'11 giugno 2008<sup id="cite_ref-nasa_4-0" class="reference"><a href="#cite_note-nasa-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Il termine è stato annunciato al termine dell'incontro insieme ad una definizione grandemente semplificata: tutti i pianeti nani transnettuniani sono plutoidi<sup id="cite_ref-IAU0804_1-1" class="reference"><a href="#cite_note-IAU0804-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>. </p> <div class="mw-heading mw-heading2"><h2 id="Processo_di_assegnazione_del_nome_per_i_plutoidi">Processo di assegnazione del nome per i plutoidi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Plutoide&veaction=edit&section=2" title="Modifica la sezione Processo di assegnazione del nome per i plutoidi" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Plutoide&action=edit&section=2" title="Edit section's source code: Processo di assegnazione del nome per i plutoidi"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>La creazione del termine "pianeta nano" ha creato alcune ambiguità tra due gruppi di lavoro dell'UAI sulla responsabilità di assegnazione dei nomi ai pianeti nani.

In concomitanza dell'annuncio della nuova classe dei plutoidi, l'11 giugno <a href="/wiki/2008" title="2008">2008</a> l'Unione Astronomia Internazionale ha istituzionalizzato tale processo collaborativo che coinvolge i due gruppi di lavoro nell'assegnazione del nome ai nuovi plutoidi. </p><p>In accordo con le linee guida per la nomenclatura dei corpi minori, la priorità sarà data ai nomi proposti dagli scopritori ed i plutoidi non possono condividere il nome con un altro <a href="/wiki/Corpo_minore" title="Corpo minore">corpo minore</a> del Sistema solare. </p> <div class="mw-heading mw-heading3"><h3 id="Complicazioni_relative_alla_definizione_di_"pianeta_nano""><span id="Complicazioni_relative_alla_definizione_di_.22pianeta_nano.22"></span>Complicazioni relative alla definizione di "pianeta nano"</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Plutoide&veaction=edit&section=3" title="Modifica la sezione Complicazioni relative alla definizione di "pianeta nano"" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Plutoide&action=edit&section=3" title="Edit section's source code: Complicazioni relative alla definizione di "pianeta nano""><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Quando la definizione di "pianeta nano" è stata stabilita durante l'Assemblea Generale dell'Unione Astronomica Internazionale del <a href="/wiki/2006" title="2006">2006</a>, <a href="/wiki/Cerere_(astronomia)" title="Cerere (astronomia)">Cerere</a>, Plutone ed Eris sono stati identificati per definizione come i primi membri della classe dei pianeti nani.
