Makemake (minor-planet designation 136472 Makemake) is a dwarf planet (and plutoid) 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's extremely low average temperature, about 30 K (−243.2 °C), means its surface is covered with methane, ethane, and possibly nitrogen ices.

Makemake was discovered on March 31, 2005, by a team led by Michael E. Brown, and announced on July 29, 2005. Initially, it was known as 2005 FY9 and later given the minor-planet number 136472. Makemake was recognized as a dwarf planet by the International Astronomical Union (IAU) in July 2008. Its name derives from Makemake in the mythology of the Rapa Nui people of Easter Island.

History - Name

he provisional designation 2005 FY9 was given to Makemake when the discovery was made public. Before that, the discovery team used the codename "Easterbunny" for the object, because of its discovery shortly after Easter.

In July 2008, in accordance with IAU rules for classical Kuiper belt objects, 2005 FY9 was given the name of a creator deity. The name of Makemake, the creator of humanity and god of fertility in the myths of the Rapa Nui, the native people of Easter Island, was chosen in part to preserve the object's connection with Easter.

Physical Characteristics


Makemake is currently visually the second-brightest Kuiper belt object after Pluto, having a March opposition apparent magnitude of 17.0[13] in the constellation Coma Berenices.[14]This is bright enough to be visible using a high-end amateur telescope.
