'''Haumea''' ([[Simbol planet|simbol]]: [[File:Haumea symbol (fixed width).svg|16px|🝻]];<ref>{{cite web |url= https://www.jpl.nasa.gov/infographics/what-is-a-dwarf-planet |author= JPL/NASA |date= 2015-04-22 |website= Jet Propulsion Laboratory |title= What is a Dwarf Planet? |access-date= 2022-01-19 |archive-date= 2021-01-19 |archive-url= https://web.archive.org/web/20210119181743/https://www.jpl.nasa.gov/infographics/what-is-a-dwarf-planet |dead-url= no }}</ref> {{pron-en|haʊˈmeɪə}} ''how-<small>MAY</small>-ə''), secara resmi disebut '''(136108) Haumea''' dan sebutan sementara '''(136108) 2003 EL61''' adalah [[planet katai]] di [[sabuk Kuiper]], secara kasar sekitar sepertiga massa [[Pluto]], ditemukan oleh tim [[Michael E. Brown|Mike Brown]] di [[Caltech]] di [[Amerika Serikat]] atau [[José Luis Ortiz Moreno|J. L. Ortiz]] et al. dari Instituto de Astrofísica de Andalucía di [[Observatorium Sierra Nevada]] di [[Spanyol]] (masih merupakan kontroversi). [[Minor Planet Center]] menyatakan grup Ortiz sebagai penemu karena merupakan yang pertama mengumumkan objek tersebut. Pada tanggal 17 September 2008, Haumea diklasifikasikan sebagai planet katai oleh IAU. Haumea dikitari oleh dua satelit alami yang diberi nama Namaka, dan Hi'iaka, keduanya merupakan asteroid yang terperangkap oleh medan gravitasi Haumea. Haumea tergolong planet katai unik, karena memiliki bentuk elips. Haumea diperkirakan mempunyai luas permukaan sekitar 2×10^7 km2 atau 20,000,000 km2 yang berarti bahwa Haumea memiliki luas permukaan yang hanya sedikit lebih besar dari Negara Rusia.😃
