Makemake (minor-planet designation 136472 Makemake) is a likely dwarf planet and perhaps the second largest Kuiper belt object in the classical population, with a diameter approximately two-thirds that of Pluto. Makemake has one known satellite, S/2015 (136472) 1.
Makemake was named after the Rapanui god of fertility.
Along with fellow dwarf planets Pluto, Eris and Haumea, Makemake is located in the Kuiper Belt, a region outside the orbit of Neptune. Slightly smaller than Pluto, Makemake is the second-brightest object in the Kuiper Belt as seen from Earth (while Pluto is the brightest).
With an estimated mean density of 1.4–3.2 g/cm³, Makemake is believed to be differentiated between an icy surface and a rocky core. Like Pluto and Eris, the surface ice is believed to be composed largely of frozen methane (CH4) and ethane (C2H6).
Makemake has one provisional moon, S/2015 (136472) 1 and nicknamed MK 2. It is more than 1,300 times fainter than Makemake.
Makemake takes 305 Earth years to make one trip around the sun. As Makemake orbits the sun, it completes one rotation every 22 and a half hours, making its day length similar to Earth and Mars.
The temperature on Makemake is usually around -406 degrees Fahrenheit or – 243 degrees Celsius.
