Nov\u00e9 \u00fadaje pritom nezmenili samotn\u00fa dr\u00e1hu asteroidu a iba zlep\u0161ili presnos\u0165 meran\u00ed, v\u010faka \u010domu je mo\u017en\u00e9 presnej\u0161ie predpoveda\u0165 jeho polohu. T\u00edm veden\u00fd Laborat\u00f3riom aplikovanej fyziky Univerzity Johns Hopkins sa zameral na vyu\u017eitie teleskopu Webb. Asteroid 2024 YR4 bol po prv\u00fd raz objaven\u00fd koncom roka 2024 syst\u00e9mom Asteroid Terrestrial-impact Last Alert System (ATLAS) v \u010cile. Prv\u00e9 sledovania nazna\u010dovali mal\u00fa mo\u017enos\u0165, \u017ee by mohol zasiahnu\u0165 Zem, \u010do pritiahlo pozornos\u0165 vedcov.

Emeritn\u00fd profesor astron\u00f3mie na Durhamskej univerzite, Martin Ward uviedol: \u201eSp\u00f4sob, ak\u00fdm sa tieto percent\u00e1 pravdepodobnosti zr\u00e1\u017eky po\u010d\u00edtaj\u00fa, je zalo\u017een\u00fd na extrapol\u00e1ci\u00e1ch trajekt\u00f3rie asteroidu a polohy Zeme v \u010dase, ke\u010f asteroid doraz\u00ed. S prib\u00fadaj\u00facimi \u00fadajmi sa tieto v\u00fdpo\u010dty postupne spres\u0148uj\u00fa. Predstavte si to ako kruh na oblohe (ove\u013ea v\u00e4\u010d\u0161\u00ed ne\u017e samotn\u00fd asteroid). Smer bud\u00faceho pohybu spolu s polohou Zeme m\u00f4\u017ee vies\u0165 \u013eubovo\u013en\u00fa \u010diaru z tohto kruhu smerom k Zemi. V\u00e4\u010d\u0161ina tak\u00fdchto \u010diar Zem minie, no niektor\u00e9 by ju mohli zasiahnu\u0165.\u201c <\/p>\n

Je to ve\u013emi n\u00e1ro\u010dn\u00e9 predpoveda\u0165<\/p>\n

Doktor Darren Baskill z Univerzity v Sussexe vysvetlil, pre\u010do je predpovedanie v\u00fdsledkov vo vesm\u00edre ve\u013emi n\u00e1ro\u010dn\u00e9. \u201eAsteroid prelet\u00ed okolo Zeme vo vzdialenosti men\u0161ej ako obe\u017en\u00e1 dr\u00e1ha Mesiaca zvy\u010dajne pribli\u017ene raz za mesiac, \u010do je z kozmick\u00e9ho h\u013eadiska ve\u013emi bl\u00edzko. Naposledy sa to stalo 4. febru\u00e1ra 2025, ke\u010f okolo n\u00e1s preletel asteroid s priemerom 26 metrov. Sledova\u0165 pribli\u017euj\u00faci sa asteroid je ako sledova\u0165 dlh\u00fd \u00fader v\u00a0biliarde. Neviete, \u010di gu\u013ea skon\u010d\u00ed v diere, a\u017e do \u00faplne poslednej chv\u00edle, a v\u017edy existuje \u0161anca, \u017ee naraz\u00ed do okraja a minie. Aj preto je okolo asteroidu to\u013eko neistoty. Samozrejme, vzdialenosti v astron\u00f3mii s\u00fa ove\u013ea, ove\u013ea v\u00e4\u010d\u0161ie a preto s\u00fa presn\u00e9 dlhodob\u00e9 predpovede ve\u013emi n\u00e1ro\u010dn\u00e9.\u201c<\/p>\n","protected":false},"excerpt":{"rendered":"NASA – Asteroid 2024 YR4, ktor\u00fd vedci v minulosti pozorne sledovali kv\u00f4li mo\u017enej kol\u00edzii s Mesiacom, napokon n\u00e1\u0161ho…\n","protected":false},"author":2,"featured_media":21501,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[32],"tags":[10446,34,37,10447,10449,33,43,40,39,42,41,36,10448,38,35],"class_list":{"0":"post-21500","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-spravy","8":"tag-asteroid","9":"tag-headlines","10":"tag-hlavne-spravy","11":"tag-kolizia","12":"tag-mesiac","13":"tag-news","14":"tag-sk","15":"tag-slovak","16":"tag-slovakia","17":"tag-slovencina","18":"tag-slovensko","19":"tag-spravy","20":"tag-teleskop","21":"tag-titulky","22":"tag-top-stories"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@sk\/116248664014459579","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/21500","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/comments?post=21500"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/21500\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media\/21501"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media?parent=21500"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/categories?post=21500"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/tags?post=21500"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
