Makemake je t\u0159et\u00ed nejv\u011bt\u0161\u00ed zn\u00e1m\u00fd objekt v Kuiperov\u011b p\u00e1su, po Plutu a Eris. Je klasifikov\u00e1na jako trpasli\u010d\u00ed planeta, co\u017e znamen\u00e1, \u017ee je p\u0159\u00edli\u0161 mal\u00e1 a nepravideln\u00e9ho tvaru na to, aby byla pova\u017eov\u00e1na za plnohodnotnou planetu. Makemake se nach\u00e1z\u00ed miliardy kilometr\u016f za ob\u011b\u017enou dr\u00e1hou Neptunu a skl\u00e1d\u00e1 se z ledu, hornin a dal\u0161\u00edch materi\u00e1l\u016f.<\/p>\n\n
M\u011bs\u00edc ob\u00edhaj\u00edc\u00ed Makemake byl pojmenov\u00e1n MK2, neboli S\/2015 (136472) 1. M\u00e1 pr\u016fm\u011br p\u0159ibli\u017en\u011b 200 kilometr\u016f a na sn\u00edmc\u00edch z Hubbla se jev\u00ed jako slab\u00e1 te\u010dka. Astronomov\u00e9 se domn\u00edvaj\u00ed, \u017ee ob\u011b\u017en\u00e1 dr\u00e1ha MK2 je pravd\u011bpodobn\u011b vid\u011bna z boku, co\u017e znamen\u00e1, \u017ee je \u010dasto obt\u00ed\u017en\u00e9 ji vid\u011bt, proto\u017ee se ztr\u00e1c\u00ed v z\u00e1\u0159i Makemake.<\/p>\n\n
Prvn\u00ed odhady nazna\u010duj\u00ed, \u017ee ob\u011bh MK2 kolem Makemake trv\u00e1 12 a\u017e 660 dn\u00ed. M\u011bs\u00edc se nach\u00e1z\u00ed p\u0159ibli\u017en\u011b 21 000 kilometr\u016f od Makemake.

Tvar a vzd\u00e1lenost ob\u011b\u017en\u00e9 dr\u00e1hy MK2 by mohly poskytnout cenn\u00e9 stopy o tom, jak vznikl. Astronomov\u00e9 se domn\u00edvaj\u00ed, \u017ee MK2 mohl vzniknout p\u0159i sr\u00e1\u017ece mezi Makemake a jin\u00fdm objektem v Kuiperov\u011b p\u00e1su. Studium MK2 m\u016f\u017ee v\u011bdc\u016fm poskytnout informace o procesech, kter\u00e9 formovaly vn\u011bj\u0161\u00ed slune\u010dn\u00ed soustavu p\u0159ed miliardami let.<\/p>\n\n
Objev MK2 vyvolal mezi astronomy nad\u0161en\u00ed a otev\u0159el nov\u00e9 mo\u017enosti pro v\u00fdzkum. Hubble\u016fv vesm\u00edrn\u00fd teleskop a jeho n\u00e1stupce, Vesm\u00edrn\u00fd teleskop Jamese Webba, budou v nadch\u00e1zej\u00edc\u00edch letech vyu\u017e\u00edv\u00e1ny ke studiu MK2 podrobn\u011bji. Tato pozorov\u00e1n\u00ed pomohou astronom\u016fm pochopit povahu MK2 a jeho vztah k planet\u011b Makemake.<\/p>\n\n
Objev MK2 je d\u016fle\u017eit\u00fd nejen pro pochopen\u00ed Makemake, ale tak\u00e9 pro srovn\u00e1vac\u00ed planetologii, studium r\u016fzn\u00fdch planet a jejich m\u011bs\u00edc\u016f. Porovn\u00e1n\u00edm MK2 s jin\u00fdmi m\u011bs\u00edci ve slune\u010dn\u00ed soustav\u011b mohou astronomov\u00e9 z\u00edskat informace o rozmanitosti planet\u00e1rn\u00edch syst\u00e9m\u016f a procesech, kter\u00e9 je formuj\u00ed.<\/p>\n\n
