High Quality Content by WIKIPEDIA articles! Makemake, formally designated (136472) Makemake, is a large dwarf planet and plutoid, perhaps the largest Kuiper belt object (KBO) in the classical KBO population. Its diameter is roughly three-quarters that of Pluto. Makemake has no known satellites, which makes it unique among the largest KBOs. Its extremely low average temperature, about 30 K (-243.2 °C), means its surface is covered with methane, ethane, and possibly nitrogen ices.
