ʻO ka pōʻino o ka mahina e hoʻokokoke ana i ka honua e hoʻopau i ko mākou ola

ʻO ka hoʻokokoke ʻana o ka mahina i ka honua e hoʻonui i ka wikiwiki o ka ʻōwili ʻana o ka honua a puni kona axis, e like me ke kānāwai o ka mālama ʻana i ka momentum angular. I kēia manawa, e hoʻoulu ʻia nā makani ʻino ma muli o ka wikiwiki o ka holo ʻana o ka lewa. A pōkole ka lā ma ka Honua.

No ka mea nānā, e ʻike nui ʻia ka mahina i kona kokoke ʻana i ka Honua, kahi e kōkua ai i ka pale ʻana i nā kukuna o ka lā. No laila, e lilo ana ka pō o ka lā i mea maʻamau.

A inā hoʻokokoke ka mahina, a hiki i ka mea i kapa ʻia ʻo "Roche palena" (ka mamao e paʻa ai ke kino lani e kona ʻumekaumaha i ka wā e hoʻokokoke aku ai i kahi kino ʻē aʻe), e wāwahi a haki ka mahina ma muli o ka ikaika o ke kai. mai ka umekaumaha o ka honua. ʻO kēia mau ʻāpana wāwahi e hana i nā apo ma ka Honua, e like me ko Saturn. Akā naʻe, ʻaʻole e liʻuliʻu ma mua o ka hāʻule ʻana o kēia mau ʻāpana i ka Honua e like me nā kaukani asteroids.

ʻOiaʻiʻo, ua loaʻa kekahi mea like me kēia ʻano pōʻino i kā mākou ʻōnaehana solar. I ka makahiki 1992 ua hoʻokokoke ka comet Shoemaker-Levy 9) iā Jupiter a ua ʻoi aku ma mua o ka palena ʻo Roche o Jupiter, a ua ʻoki ʻia a ʻoi aku ma mua o iwakālua mau ʻāpana, a hoʻomaka e hoʻopuni iā ​​​​ia, a laila hāʻule kekahi ma hope o Jupiter i ka makahiki 9 AD. Ua manaʻo ʻia kona mana luku ma 1994 miliona mau pōkā atomika!

No laila, ʻike maopopo ʻia nā hopena o ke kūlana hiki ke hoʻokokoke ka mahina i ka Honua. Ua hoʻoikaika kēia hopena pōʻino i kekahi mau hana o dystopia a me apocalypse. ʻO ka ʻoiaʻiʻo, ke neʻe nei ka mahina mai ka Honua ma 3.8 knm i kēlā me kēia makahiki. No laila, ʻaʻole paha e hiki mai kekahi mau hanana hypothetical e like me nā ʻōlaʻi, nā lua pele, a me nā makani ʻino e hiki mai ana, ʻaʻole mākou e ʻike i ka pōloli mau, a ʻaʻohe apo e like me nā apo o Saturn, a e mau ka mahina. he kumu o ka palekana a me ke kūpaʻa no ka honua.
