Abaphandi abafumene i-plutoid 2007 OR10, eyona planethi inkulu engachazwanga ngegama kwiSolar System, bagqiba ekubeni banike igama kumzimba wesibhakabhaka. Umyalezo ohambelanayo wapapashwa kwiwebhusayithi yoMbutho wePlanethi. Abaphandi bakhetha iindlela ezintathu ezihlangabezana neemfuno ze-International Astronomical Union, enye yazo iya kuba ligama le-plutoid.
Umzimba wasezulwini ochaphazelekayo wafunyanwa kwi-2007 ngososayensi beplanethi uMegan Schwamb noMichael Brown. Kangangexesha elide, iplanethi encinci yabonwa njengommelwane oqhelekileyo wePluto, ububanzi bayo bumalunga ne-1280 km. Kwiminyaka emininzi edlulileyo, i-2007 OR10 yatsala umdla wabaphandi abafumanisa ukuba i-diameter yokwenyani yento yayiyi-300 km enkulu kunokuba bekuqikelelwe ngaphambili. Ngaloo ndlela, i-plutoid yajika ukusuka kummi oqhelekileyo webhanti ye-Kuiper ibe yiplanethi enkulu "engenagama". Uphando olongezelelekileyo lwanceda ukufumanisa ukuba iplanethi encinci inenyanga yayo enobubanzi obumalunga neekhilomitha ezingama-250.
Abaphandi bakhetha amagama amathathu anokwenzeka, ngalinye linxulunyaniswa nezithixo ezivela kubantu abahlukeneyo behlabathi. I-Gungun lukhetho lokuqala olucetywayo kwaye ikwaligama lothixo wamanzi kwintsomi yamaTshayina. Ngokwentsomi, esi sithixo sinxulumene ngokuthe ngqo nento yokuba i-axis yokujikeleza kweplanethi yethu ikwi-engile ukuya kumjikelezo wayo. Inketho yesibini yayiligama likathixokazi wamandulo waseJamani uHolda. Uthathwa njengomphathi wezolimo, kwaye ukwasebenza njengenkokeli ye-Wild Hunt (iqela labakhweli bamahashe abazingela imiphefumlo yabantu). Owokugqibela kolu luhlu ligama le-ace Vili yaseScandinavia, owathi, ngokwentsomi, akayena nje umntakwabo kaTor odumileyo, kodwa naye usebenza njengomnye wabadali bendalo yonke kwaye uyabaxhasa abantu.
Ukuvota okuvulekileyo kwiwebhusayithi kuya kuhlala kude kube nguMeyi 10, 2019, emva koko ukhetho lokuphumelela luya kuthunyelwa kwi-International Astronomical Union ukuze ivunywe ekugqibeleni.
