Makemake (pronounced Mah-keh Mah-keh) is a dwarf planet that was first discovered in 2005.
Its radius is roughly three-quarters that of Pluto. Makemake has no known moons and observations suggest an extremely low average temperature of around -243°C (or 30K).
Makemake is also a type of plutoid. These are dwarf planets that circle the Sun beyond the orbit of Neptune. It's so far away that if we sent a spacecraft to it, when it was at it's closest point to the Earth, even with a boost given by Jupiter, it would take 16 years for the spacecraft to arrive at Makemake.
