ESA

Nui nā kumuwaiwai i hoʻolaʻa ʻia e nā ʻoihana ʻokoʻa a puni ka honua i ka noiʻi ākea a me ka ʻimi ʻana. Ma loko o kēia mau mea o ke kālā a me nā limahana, pono mākou e hōʻike he hoʻokahi, he mea nui kekahi, i hoʻolaʻa ʻia no ka ʻimi ākea a me ka hoʻāʻo ʻana. e ʻike a ʻike i nā ʻano hoʻoweliweli i kā mākou honua honua Honua aloha.

Ma muli o kēia, ʻaʻole ia he mea kupanaha i kēlā me kēia manawa loaʻa iā mākou nā hōʻike e haʻi iā mākou pehea kekahi asteroids, keu hoʻi nā mea nui loa i hiki ke hoʻokau i kekahi makaʻi i ka Honua, pili loa iā ia. E loaʻa iā mākou kahi hiʻohiʻona maopopo i ka hope ʻOkakopa 12 o kēia makahiki 2017, kahi lā e like me ka mea i hōʻike ʻia e ka ESA, ʻĀina Mokuna ʻEulopa, asteroid 2012 TC4 e hala kokoke loa i ka Honua.

asteroid

ʻO kahi asteroid 15 a 30 mau mika i ke anawaena e hala kokoke i ka Honua akā me ka ʻole o ka hoʻokumu ʻana i kekahi ʻano hopena a i ʻole ka pōʻino

E like me ka inoa o ka asteroid e hōʻike nei, ua ʻikea ʻia kona alo i ka makahiki 2012 e ka Pan-STARRS teleskopa nānā panoramic ma Hawaii. No kāna ʻano hoihoi loa, ʻōlelo e kamaʻilio nei mākou e pili ana i asteroid ma kahi o 15 a 30 mau mika ke anawaena, kahi nui e like paha me ka liʻiliʻi, keu hoʻi inā hoʻohālikelike mākou iā ia me ka mea nui i hala ma kahi kokoke i ka Honua a ma kahi o 620 mau mika ke anawaena, akā inā ia i ku i ka honua, ʻaʻole paha e hiki ke hōʻino nui iā ia, akā inā hiki iā ia ke kumu i kekahi mau pilikia a mākou e hoʻolālā ai a ma mua o ka mākaukau o ke alo, no laila ke neʻe nei nā neʻe like ʻole nānā ʻia i nā manawa āpau.

Wahi a nā manaʻo i hana ʻia e ka poʻe loea mai ESA iho a me ka helu o nā astronomers e nānā nei i kāna neʻe, ua manaʻo ʻia e lele ka asteroid 2012 TC4 ma luna o kā mākou honua ma kahi ka wikiwiki o 14 kilomita i kekona hele ana i kahi ka mamao o 44.000 mau kilomita. Kuhi paha kēia mamao ʻaʻole e hoʻopili ka asteroid i ka hana o nā satelite mamao loa mai ka orbit geostationary o ka Honua a aia ma kahi o 36.000 mau kilomita mai ka Honua.

2012 TC4

Inā kū ka asteroid e like me 2012 TC4 i ka Honua ʻaʻole ia he hopena weliweli

Wahi a nā ʻōlelo akeakamai ʻO Detlef Koschny, lālā o kēia manawa o ka hui noiʻi o nā mea ʻo Earth Hema, kahi kime i kālā pololei ʻia e nā kālā ESA:

ʻIke maopopo loa mākou ʻaʻohe hiki ke loaʻa kēia mea i ka Honua. ʻAʻohe mea weliweli.

Eia naʻe… He aha ka mea e hana ai inā kūʻē i nā ala āpau, hoʻololi a hope loa ka asteroid i kāna alahele a me nā poʻo i ka Honua? ʻIke ʻia a e like me ka loea o ka ESA i nīnau ʻia e pili ana i kēia hiki ke manaʻo, akā ʻaʻole paha ia, ʻo ka hopena o kēia asteroid me ka Honua e like me ka hopena o Chelyabinsk, kahi kūlanakauhale ma Lūkia, i 2013.

Ma ke ʻano he hoʻomanaʻo, e haʻi aku iā ʻoe e kamaʻilio ana mākou e pili ana i kahi ʻāpana o ka comet i pohā i ka lewa. ʻO ka nalu haʻalulu i hana i kēia pahū i kumu Ua wāwahi ʻia nā puka aniani o nā hale he 6.000 a ʻoi aku ka hōʻeha ʻia o 1.500 poʻe. E like me kāu e ʻike ai, ʻo ka ʻāpana maikaʻi o kēia ʻaʻole mākou e kamaʻilio e pili ana i kahi hanana me nā hopena weliweli a i ʻole nā ​​mea like, ʻoiai mākou e hoʻomākaukau.

Mālama Honua

E loaʻa i kā mākou ʻepekema ka manawa kūpono e noiʻi i ka orbit a me ka haku ʻana o kēia ʻano celestial body

Ke waiho nei i kahi hiki ke loaʻa i kekahi mea e like me kēia, ʻo ka ʻoiaʻiʻo ua loaʻa i ka poʻe ʻepekema a puni ka honua i ka manawa kūpono e aʻo hou e pili ana i ka orbit a me ka hoʻohui o asteroids. E like me ka hiki ke heluhelu ʻia i loko o ka paʻi paʻi i paʻi ʻia e ka poʻe loea o ka ESA:

E hoʻolālā kēia hanana i ka pūnaewele puni honua o nā hale kiaʻi a me nā ʻoihana noiʻi e hana nei i ka pale pale honua.

ʻIke hou aku: Nā ʻenehana


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia. i hāliu aku i koi 'ia kula *
