Ka\u017ed\u00fd \u010dlov\u011bk na Zemi je cestovatelem vesm\u00edrem. Zaprv\u00e9, Zem\u011b ob\u00edh\u00e1 kolem Slunce rychlost\u00ed 30 km\/s \u2013 co\u017e je 45kr\u00e1t rychleji ne\u017e Concorde. Jedna ob\u011b\u017en\u00e1 dr\u00e1ha kolem Slunce trv\u00e1 365 dn\u00ed (jeden rok).<\/p>\n<\/div>\n

Krom\u011b toho se ot\u00e1\u010d\u00ed velmi rychle, jako k\u00e1\u010da naklon\u011bn\u00e1 na jednu stranu. Lid\u00e9 \u017eij\u00edc\u00ed na rovn\u00edku se pohybuj\u00ed ze z\u00e1padu na v\u00fdchod rychlost\u00ed 1 670 km za hodinu. (U lid\u00ed \u017eij\u00edc\u00edch v bl\u00edzkosti p\u00f3l\u016f je tato rychlost ni\u017e\u0161\u00ed.) Jeliko\u017e se v\u0161e kolem n\u00e1s pohybuje stejn\u00fdm zp\u016fsobem, obvykle si tuto vysokou rychlost, jakou se pohybujeme, ani neuv\u011bdomujeme. Nejviditeln\u011bj\u0161\u00edm zp\u016fsobem, jak to poznat, je pozorovat Slunce, M\u011bs\u00edc a hv\u011bzdy, jak se zd\u00e1nliv\u011b pohybuj\u00ed po obloze.<\/p>\n

Ji\u017en\u011b od rovn\u00edku jsou ro\u010dn\u00ed obdob\u00ed p\u0159esn\u011b opa\u010dn\u00e1.<\/p>","protected":false},"excerpt":{"rendered":"
