Ua ʻike ʻia i kēia manawa, akā ua hāʻawi mua ia iā mākou i ka pīhoihoi: asteroid 2023DW e hoʻokokoke i ka Honua ma kahi ala pōʻino ma kahi o ʻelua mau makahiki. ʻO kēia pōhaku, ka nui o ka loko ʻauʻau ʻOlumepika, he hoʻokahi ma 600 ka manawa e hui pono ai me ko kākou honua, e like me ka hōʻike ʻana e NASA.
ʻO kēia mea wale nō ka mea ma ka papa inoa pilikia o ke keʻena kikowaena US e loaʻa ana ka helu o 1 ma ka Turin Scale, kahi anana e hoʻokaʻawale i ka pilikia o kahi mea e pili ana i ka Honua. ʻO nā kino ʻē aʻe a pau, ma ka liʻiliʻi loa i kēia manawa, he 0 ka helu ma ka pālākiō. Akā ʻoiai ʻoi aku ka kiʻekiʻe ma mua o ka awelika o ka pilikia no nā asteroids kokoke i ka Honua, ua ʻōlelo ʻo NASA he "liʻiliʻi liʻiliʻi loa ia" o ka hopena. Eia kekahi, ke manaʻo nei mākou e emi iho kēia pae o ka pilikia no ka mea he nui ka nānā ʻana o ka asteroid.
ʻIke ʻia no ka manawa mua ma Pepeluali 27, ua manaʻo ʻia ka asteroid i kapa ʻia ʻo 2023 DW, ʻo ia hoʻi ma kahi o 50 mau mika ke anawaena, ua manaʻo ʻia e kokoke loa i ka Honua ma Pepeluali 14, 2046; Mai ka lā Malaki 8, ua wānana ka European Space Agency's Near-Earth Object Coordination Center i kahi 1 i 625 manawa o ka hopena pololei, akā naʻe, helu hou ʻia kēia mau mea i kēlā me kēia lā.
"ʻO ka manawa pinepine, i ka uhi ʻia ʻana o nā mea hou no ka manawa mua, pono nā pule he nui e hōʻemi i ka maopopo ʻole a kūpono i kā lākou orbit i ka wā e hiki mai ana," i hoʻopuka ai ʻo NASA. "E hoʻomau ka poʻe loiloi Orbit i ka nānā ʻana i ka asteroid 2023 DW a e hoʻonui i nā wānana i ka hiki ʻana mai o nā ʻikepili hou aku."
Akā, pehea inā e hiki mai ana?
Eia naʻe, inā e hoʻokō ʻia nā wānana ʻino loa, he aha ka hopena? ʻAʻole i like ka pōʻino e like me ka asteroid i pepehi i nā dinosaurs 66 miliona mau makahiki i hala aku nei, ʻo ia hoʻi he 12 mau kilomita ka lōʻihi. Eia nō naʻe, hiki i ka 2023 DW ke hōʻeha i ka pōʻino koʻikoʻi inā pae ʻo ia ma kahi kokoke i ke kūlanakauhale nui a i ʻole ka nui o nā kānaka. No ka laʻana, ua pahū ka meteorite i ka hapalua o ka nui o 2023 DW ma Chelyabinsk, Rūsia, i ka makahiki 2013, e hana ana i ka nalu haʻalulu i hōʻino i nā kilomita o nā hale a paʻi i 1500 poʻe, a me ka hoʻopilikia nui ʻana i nā kilomita o nā hale.
ʻOiai ʻaʻole paʻa ka hopena me 2023 DW, ʻaʻole kū wale ke kanaka. I ka pule i hala aku nei, ua hoʻopuka nā kānaka ʻepekema NASA i ʻelima mau haʻawina e hōʻoia ana ua hoʻololi maikaʻi ka misionari DART i ke ala o kahi asteroid liʻiliʻi ma hope o ka hāʻule ʻana o kahi mokulele i loko. Ke hana nei nā mikiona ukali e hoʻomaʻemaʻe hou i ka pono o kēia pale honua.
