AI overview

Makemake is a dwarf planet in the Kuiper Belt beyond Neptune's orbit, making it the fourth largest trans-Neptunian object and the largest member of the classical Kuiper Belt. Its discovery in 2005 by American astronomers at Palomar Observatory was significant enough to contribute to the scientific decision to reclassify Pluto as a dwarf planet in 2006.

Makemake, ufficialmente designato (136472) Makemake, precedentemente noto con la designazione provvisoria di (136472) 2005 FY9) è il terzo pianeta nano per dimensioni del sistema solare ed è appartenente alla classe dei plutoidi. Il suo diametro è pari all'incirca a 3/4 di quello di Plutone. La sua orbita è per intero situata esternamente rispetto all'orbita di Nettuno, pertanto è corretto definirlo un oggetto transnettuniano, appartenente al gruppo dei cubewani. Ha un satellite conosciuto, S/2015 (136472) 1, la cui scoperta è stata resa nota nell'aprile del 2016. La temperatura estremamente bassa (circa 30 K) che si registra sulla sua superficie fa sì che essa sia ricoperta da ghiacci di metano, etano e probabilmente azoto. Il suo nome richiama la figura di Makemake, divinità della creazione secondo la mitologia pasquense.
