Minor dziko - Mtumiki wochokera danga

Pamwamba ife, mu malo pakati pa zili m'njira ya mapulaneti aakulu ikuyenda mamiliyoni cuttings chachilendo kwambiri ndi zachilendo. Aliyense Chip amatchedwa "zazing'ono dziko" ali chodabwitsa chake nkhani, ndi inextricably zogwirizana ndi zamoyo wa dongosolo la zowalitsa. Asayansi ambiri amakhulupirira kuti amvetse zinsinsi za mapangidwe dongosolo lonse la danga otizungulira kubisa zinthu izi zachilendo. Aliyense dziko yaing'ono (asteroid) aumbike chifukwa cha zochitika zapadera - chiyambi cha dongosolo la zowalitsa.

Ndipotu, awa onse matupi akumwamba ndi mankhwala ndi mboni chete wa mndandanda wonse wa masoka mphamvu yoposera dziko kuti zinachititsa kuti pakhale a dongosolo lathu ndi khola m'mapulaneti. Iliyonse yaing'ono dziko - mtundu wa mbiri ya zochitika zoopsa zimene zinachitika mu gawo ili la Veselennoy zinayi biliyoni theka zapitazo.

apadera, poyerekeza ndi mapulaneti asanu ndi anayi akuluakulu likuzungulira dzuwa, ndi kuti asteroids, ndi ukoma wa msinkhu wawo waung'ono ndi kutalika lalikulu nyenyezi, akhala akukonza laling'ono kwambiri kusintha chisinthiko. M'mawu ena, anapanga ku nkhani mofanana ndi ena a zinthu za dongosolo lathu mapulaneti, asteroids akadali kusunga umboni wa nyengo wakale wa Ngozi Wamkulu.

Minor dziko lapansili dzuŵa - yekha zakuthambo mmenemo kuti sayansi yamakono maphunziro m'njira ziwiri - kudzera mwa zakuthambo ndi opanda spacecraft, komanso mwachindunji mu Laboratories Padziko Lapansi. Pafupifupi onse milandu, pamene n'zotheka kudziwa enieni njira yodutsamo wa kugwa kwa miyala yochokera, izo likukhalira kuti anabwera padziko lathuli ku malo apadera mu gawo lowonekeratu wa chilengedwe chonse - ndi asteroid lamba, amene analogue silinakwaniritsidwe wapezeka chilichonse cha machitidwe lotseguka m'mapulaneti.

Palibe kukaika kuti kugwa kwa miyala yochokera uliwonse ndi dziko laling'ono - thupi ndi kwathunthu chiyambi chomwecho ndi zikuchokera. Nthawi kawirikawiri, pamene asteroid ikuyenda panjira kwambiri elliptical (chomwe nthawi zambiri khalidwe la iwo), kudutsa kanjira dziko lapansi, ndi dziko laling'ono ali mwayi onse kulowa labu ndi pansi yofufuza. Kodi tinganene za ena "anthu" a dongosolo la zowalitsa. Izi ndi wofunika kwambiri kwa mapulaneti yaing'ono kwa dziko la sayansi.

Chikhalidwe yunifolomu ya meteorites ndi asteroids kwambiri zambiri mwayi wa kuphunzira zapitazi. Mwa kaphatikizidwe zokhudza mapulaneti ang'ono analandira kudzera zakuthambo, deta maphunziro a meteorites, ndipo mukhoza kupeza mayankho a mafunso angapo Cosmological. Makamaka, kuthetsa vuto limeneli yokhudza monga chiyambi asteroid mphete. Mwina tsiku lina adzapezeka yankho la funso lakuti: "Kodi Pali malo a zotsala zachilendo lamba lalikulu dziko amene ali ndi chiwonongeko dziko anamwalira ndipo anasiya mamiliyoni zidutswa? Kapena kodi basi chifukwa cha kuphwanya yaing'ono zakuthambo m'kati mapangidwe dongosolo lathu mapulaneti? "

Koma si mtengo wa mapulaneti zazing'ono. Opezeka meteorites mkulu maselo kulemera organic mankhwala ndi otchedwa "bungwe zinthu", amene asayansi ambiri amakhulupirira zotsalira za zinthu zakuthambo, anaika pamaso pa nkhani sayansi yamakono monga zamoyo wa zamoyo kwachilengedwenso mu malo a m'mlengalenga. Kuti mwina kuunikira pa chiyambi ndi chitukuko cha moyo padziko lapansi. N'zotheka kuti kuphunzira meteorites ndi maiko yaing'ono kuti muthetse ofunika kwambiri kwa anthu.
