Saturn je zn\u00e1m\u00fd jako \u2018p\u00e1n prstenc\u016f\u2019, a\u010dkoli i ostatn\u00ed t\u0159i ob\u0159\u00ed plynn\u00e9 planety \u2013 Jupiter, Uran a Neptun \u2013 maj\u00ed prstence. Saturnov\u00fd syst\u00e9m zauj\u00edm\u00e1 \u010destn\u00e9 m\u00edsto, proto\u017ee jeho prstence jsou mimo\u0159\u00e1dn\u011b jasn\u00e9 a velmi rozs\u00e1hl\u00e9.<\/p>\n<\/div>\n

Mohou to b\u00fdt zbytky satelitu nebo komety, kter\u00e1 se rozpadla. Kdy\u017e byly objeveny v 17. stolet\u00ed, na kresb\u00e1ch vypadaly jako obrovsk\u00e9 \u2018u\u0161i Mickeyho My\u0161i\u2019 po obou stran\u00e1ch planety. S zdokonalov\u00e1n\u00edm dalekohled\u016f si astronomov\u00e9 uv\u011bdomili, \u017ee jsou tvo\u0159eny miliony \u00falomk\u016f ledu a hornin. Mezery v prstenc\u00edch vznikly p\u016fsoben\u00edm gravitace okoln\u00edch m\u011bs\u00edc\u016f.<\/p>\n

Tyto ploch\u00e9 prstence, p\u0159ipom\u00ednaj\u00edc\u00ed obrovsk\u00e9 kompaktn\u00ed disky, maj\u00ed pr\u016fm\u011br v\u00edce ne\u017e 275 000 km \u2013 co\u017e je dost na to, aby zaplnily v\u011bt\u0161inu vzd\u00e1lenosti mezi Zem\u00ed a M\u011bs\u00edcem \u2013, ale jejich tlou\u0161\u0165ka je men\u0161\u00ed ne\u017e 1 km. Jak se Saturn a Zem\u011b pohybuj\u00ed po sv\u00fdch ob\u011b\u017en\u00fdch drah\u00e1ch nahoru a dol\u016f, m\u011bn\u00ed se i n\u00e1\u0161 pohled na prstence. V roce 2003 byly nejjasn\u011bj\u0161\u00ed a nejkr\u00e1sn\u011bj\u0161\u00ed. Ka\u017ed\u00fdch 15 let je v\u0161ak vid\u00edme z boku. Tehdy jsou neviditeln\u00e9, leda\u017ee by se na n\u011b d\u00edvalo nejv\u00fdkonn\u011bj\u0161\u00edmi dalekohledy. To je vhodn\u00e1 doba k hled\u00e1n\u00ed mal\u00fdch m\u011bs\u00edc\u016f v bl\u00edzkosti prstenc\u016f.<\/p>","protected":false},"excerpt":{"rendered":"
