ʻO ka pōʻino .. ke kokoke mai nei kahi asteroid nui i ka honua

Ke nānā pono nei ʻo NASA i kahi asteroid nunui e hele mai ana i ko kākou honua, a ke neʻe kokoke mai nei i kēia lā (Palima, Ianuali 10). Ua wehewehe ka US space agency i ka asteroid 2019 UO ma ke ʻano he "Near-Earth Object" (NEO).

Ke ʻimi nei nā kānaka ʻepekema i ʻumi kaukani mau mea kokoke i ka Honua e hōʻoiaʻiʻo ʻaʻole lākou e hui pū me ko mākou honua, no ka mea, hiki i kahi hoʻololi liʻiliʻi i ko lākou ala ke alakaʻi i ka pōʻino ma ka Honua.

Aia ma kahi o 550 mika ka lōʻihi o ka asteroid, a ke neʻe nei i ka māmā ma mua o 21 mau mile i kēlā me kēia hola. Manaʻo ʻia e hala i ka Honua ma 23:50 GMT ma Ianuali 10.

ʻO ka mea pōmaikaʻi, manaʻoʻiʻo ʻo NASA e hele ana ka pōhaku ākea kokoke i ka Honua ma kahi mamao palekana o 2.8 miliona mau mile. Wahi a ka ʻoihana lewa, ʻo kēlā me kēia mea e hele i loko o 120 miliona mau mile o ka Honua e manaʻo ʻia kokoke iā mākou.

Ua hopohopo nā kānaka ʻepekema

Ua hōʻike ʻia ua haʻi aku ka ʻoihana kikowaena ʻaʻole i hoʻopiha ʻia kāna palapala NEO, ʻo ia ka mea e hiki mai ana kahi hopena i manaʻo ʻole ʻia i kēlā me kēia manawa, kahi e hopohopo nei i nā ʻepekema a me nā loea a puni ka honua.

Ua ʻike pū ʻo ia "ua manaʻo ka poʻe loea i ka nui o ka hopena o kahi mea i pahū ma luna o Chelyabinsk, Russia, i ka makahiki 2013 - ʻo ia ka 55 kapuaʻi (17 mau mika) ka nui - hoʻokahi a ʻelua paha i ke kenekulia, a ʻoi aku ka nui o ka hopena. Ua manaʻo ʻia e emi pinepine nā mea ola ma nā haneli he nui. No nā kaukani mau makahiki, akā naʻe, no ka hemahema o ka papa inoa o NEO i kēia manawa, kahi hopena i manaʻo ʻole ʻia - e like me ka hanana Chelyabinsk - hiki ke hana i kēlā me kēia manawa. "

Ua haʻi aku ka Luna Hoʻokele o ka Center for Near-Earth Object Studies, ʻo Paul Chodas, i ka Newsweek, ʻo ka hele ʻana o nā asteroids kokoke i ka Honua he mea ia e hana ʻia ma luna o nā makahiki he mau makahiki, me ka ʻike ʻana "he mea naʻauao ke hoʻomau i nā kānaka e hahai iā lākou no nā makahiki he mau makahiki. a e noʻonoʻo pehea e ulu ai ko lākou mau ʻōpuni." E hala ka asteroid kokoke i ka Honua, ma kahi o 44 km i kēlā me kēia hola.

Ua wehewehe pū ʻo ia ʻoiai ʻo ka "pōhaku pilikua" e pili kokoke ana i ka Honua, ʻaʻole mamao loa ia i ʻole mākou e hopohopo.
