WASHINGTON – Vedci potvrdili presn\u00fd term\u00edn v\u00fdnimo\u010dn\u00e9ho kozmick\u00e9ho \u00fakazu. Obrovsk\u00fd asteroid Apofis prelet\u00ed okolo Zeme v nezvy\u010dajne malej vzdialenosti, bli\u017e\u0161ie ne\u017e niektor\u00e9 dru\u017eice.<\/p>\n
\t\t\t\t\u201eBoh chaosu\u201c mieri k Zemi<\/p>\n
Americk\u00e1 agent\u00fara NASA ozn\u00e1mila detailn\u00e9 inform\u00e1cie o prelete asteroidu (99942) Apophis, ktor\u00fd dostal prez\u00fdvku \u201eBoh chaosu\u201c. N\u00e1zov odkazuje na staroegyptsk\u00e9 bo\u017estvo sp\u00e1jan\u00e9 so skazou, no tentoraz ide sk\u00f4r o fascinuj\u00faci ne\u017e hroziv\u00fd jav.<\/p>\n
K Zemi sa pribl\u00ed\u017ei v piatok 13. apr\u00edla 2029 \u2013 d\u00e1tum, ktor\u00fd mnoh\u00ed pova\u017euj\u00fa za ne\u0161\u0165astn\u00fd. Asteroid v\u0161ak bude mo\u017en\u00e9 sledova\u0165 vo\u013en\u00fdm okom priamo na no\u010dnej oblohe.<\/p>\n
Nezvy\u010dajne tesn\u00e9 pribl\u00ed\u017eenie<\/p>\n
Apofis prelet\u00ed pribli\u017ene vo vzdialenosti 32 000 kilometrov od zemsk\u00e9ho povrchu, \u010do je menej ne\u017e obe\u017en\u00e1 dr\u00e1ha niektor\u00fdch umel\u00fdch dru\u017e\u00edc.<\/p>\n
Pre porovnanie \u2013 ide o vzdialenos\u0165 takmer 12-kr\u00e1t men\u0161iu, ne\u017e je priemern\u00e1 vzdialenos\u0165 medzi Zemou a Mesiacom.<\/p>\n
Pod\u013ea vedcov p\u00f4jde o najbli\u017e\u0161ie zaznamenan\u00e9 pribl\u00ed\u017eenie objektu takejto ve\u013ekosti v modernej hist\u00f3rii.<\/p>\n
Obavy z minulosti sa rozplynuli<\/p>\n
Ke\u010f bol asteroid objaven\u00fd v roku 2004, vedci zva\u017eovali scen\u00e1r mo\u017enej kol\u00edzie so Zemou \u2013 a to v rokoch 2029, 2036 alebo 2068. P\u00f4vodn\u00e9 v\u00fdpo\u010dty dokonca prip\u00fa\u0161\u0165ali pravdepodobnos\u0165 n\u00e1razu na \u00farovni 2,7 percenta.<\/p>\n
Postupne sa v\u0161ak v\u010faka presnej\u0161\u00edm meraniam trajekt\u00f3rie tieto obavy vyvr\u00e1tili. K\u013e\u00fa\u010dov\u00fa \u00falohu zohrali radarov\u00e9 pozorovania z roku 2021, ktor\u00e9 definit\u00edvne vyl\u00fa\u010dili riziko zr\u00e1\u017eky minim\u00e1lne na najbli\u017e\u0161ie storo\u010die.<\/p>\n
Jedine\u010dn\u00e1 pr\u00edle\u017eitos\u0165 pre vedcov<\/p>\n
Bl\u00edzky prelet Apofisu predstavuje v\u00fdnimo\u010dn\u00fa pr\u00edle\u017eitos\u0165 pre vedcov z cel\u00e9ho sveta. Takto ve\u013ek\u00e9 teleso sa tak bl\u00edzko k Zemi dost\u00e1va len mimoriadne zriedkavo.<\/p>\n
\u201eP\u00f4jde o najbli\u017e\u0161ie pribl\u00ed\u017eenie objektu tejto ve\u013ekosti, ak\u00e9 v s\u00fa\u010dasnosti pozn\u00e1me. Asteroid bude nieko\u013eko hod\u00edn vidite\u013en\u00fd vo\u013en\u00fdm okom a gravita\u010dn\u00e9 p\u00f4sobenie Zeme pravdepodobne ovplyvn\u00ed jeho rot\u00e1ciu,\u201c uviedla NASA.<\/p>\n
Tvar aj rozmery prekvapuj\u00fa<\/p>\n
Pod\u013ea doteraj\u0161\u00edch pozorovan\u00ed m\u00e1 Apofis nepravideln\u00fd tvar pripom\u00ednaj\u00faci ara\u0161id. Jeho d\u013a\u017eka dosahuje pribli\u017ene 375 metrov, \u010do je viac ne\u017e v\u00fd\u0161ka Eiffelovej ve\u017ee (asi 330 metrov).<\/p>\n
Zem sleduje tis\u00edce objektov<\/p>\n
NASA v s\u00fa\u010dasnosti monitoruje pribli\u017ene 2000 asteroidov, kom\u00e9t a \u010fal\u0161\u00edch telies, ktor\u00e9 sa m\u00f4\u017eu pribl\u00ed\u017ei\u0165 k Zemi. V\u00e4\u010d\u0161ina z nich nepredstavuje \u017eiadne riziko, ke\u010f\u017ee nezasahuj\u00fa do atmosf\u00e9ry.<\/p>\n
Len v\u00fdnimo\u010dne doch\u00e1dza k stretu s ve\u013ek\u00fdm telesom. Posledn\u00fd katastrofick\u00fd dopad podobn\u00e9ho rozsahu sa odohral pred pribli\u017ene 66 mili\u00f3nmi rokov, ke\u010f asteroid prispel k vyhynutiu dinosaurov.<\/p>\n","protected":false},"excerpt":{"rendered":"WASHINGTON – Vedci potvrdili presn\u00fd term\u00edn v\u00fdnimo\u010dn\u00e9ho kozmick\u00e9ho \u00fakazu.
