Izwe elikhanyayo, elisha kakhulu ngaphezu kweNeptune, ligoqelekile ngeqhwa le-methane.

I-Makemake iyinye yezinto ezikhulu eziziwa nge-Kuiper belt. Ingxenye yayo engaphandle ifakwe umfutho obandayo we-methane, owenza ukuthi ibonakale kakhulu.

Inyanga encane yatholakele ngo-2016. Isisindo sayo asiziwa kahle kakhulu kunaso sePluto noma iEris, futhi inani ethebulani ledatha yi-JPL’s current estimate.
