Makemake (simbol: .svg){kind=small}
;[7] pocapan jroning basa Inggris /ˌmɑːkiːˈmɑːkiː/, utawa sajeroning Rapanui 
[ˈmakeˈmake] (pitulung·info)[8]), kanthi resmi diarani (136472) Makemake, iku planit cilik ing Tata Surya sing ana ing sabuk Kuiper. Dhiameter planit cilik iki watara telung prapat Pluto.[9] Makemake ora duwé satelit. Rata-rata suhuné sing asor banget (watara 30 K) nuduhaké yèn lapisan Makemake kapérang saka metana, etana lan kamungkinan ès nitrogen.[9]
