Makemake (minor-planet designation: 136472 Makemake) ek bauna grah aur Kuiper belt ke chij me se sab se barraa hae. Iske diameter Saturn ke chaand, Iapetus ke baraabar hae, nai to Yamgrah ke 60% Iske ek jaana jaae waala satellite hae. Iske average temperature bahut kamti rahe hae, lagbhag 40 K (−230 °C), jiske matlab hae ki iske surface methane, ethane, aur solid nitrogen se covered rahe hae. Makemake me geothermal activity ke sabuut hae aur saait isme active geology aur active subsurface ocean bhi hoi.[7]
