Is é 2004 XR190 (ar a dtugtar an leasainm Buffy) uimhir 55 de réadanna an Ghrianchórais in ord a méid. Tá trastomhas níos lú ná 650 km aige. Tá a fhithis thart ar an ghrian níos sia amach ón ghrian ná fithis Neiptiúin agus tá sé ina bhall de Chrios Kuiper. Is réad tras-Neiptiúnach é agus d'fhéadfadh sé gur abhacphláinéad é freisin.
