"PARIS, July 19, 2008 - Members of the International Astronomical Union's Committee on Small Body Nomenclature (CSBN) and the IAU Working Group for Planetary System Nomenclature (WGPSN) have decided to name the newest member of the plutoid family Makemake, and have classified it as the fourth dwarf planet in our Solar System and the third plutoid.

Makemake (pronounced MAH-keh MAH-keh) is one of the largest objects known in the outer Solar System and is just slightly smaller and dimmer than Pluto, its fellow plutoid. The dwarf planet is reddish in colour and astronomers believe the surface is covered by a layer of frozen methane.

Like other plutoids, Makemake is located in a region beyond Neptune that is populated with small Solar System bodies (often referred to as the transneptunian region). The object was discovered in 2005 by a team from the California Institute of Technology led by Mike Brown and was previously known as 2005 FY9 (or unofficially "Easterbunny"). It has the IAU Minor Planet Center designation (136472). Once the orbit of a small Solar System body or candidate dwarf planet is well determined, its provisional designation (2005 FY9 in the case of Makemake) is superseded by its permanent numerical designation (136472) in the case of Makemake.

The discoverer of a Solar System object has the privilege of suggesting a name to the IAU, which judges its suitability. Mike Brown says: "We consider the naming of objects in the Solar System very carefully. Makemake's surface is covered with large amounts of almost pure methane ice, which is scientifically fascinating, but really not easily relatable to terrestrial mythology. Suddenly, it dawned on me: the island of Rapa Nui. Why hadn't I thought of this before? I wasn't familiar with the mythology of the island so I had to look it up, and I found Makemake, the chief god, the creator of humanity, and the god of fertility. I am partial to fertility gods. Eris, Makemake, and 2003 EL61 were all discovered as my wife was 3-6 months pregnant with our daughter. I have the distinct memory of feeling this fertile abundance pouring out of the entire Universe. Makemake was part of that." WGPSN and CSBN accepted the name Makemake during discussions conducted per email."
