Minor nyika - mutumwa kubva muchadenga

High pamusoro pedu, muna nzvimbo pakati kutenderera nyika zvikuru vari kutamira mamiriyoni wokumwe chaizvo uye kujairika kuchekwa. Mumwe Chip, inonzi "nyika duku" rine nyaya yayo zvinoshamisa, ari zvakabatana chaizvo pamwe shanduka ari renzou. Masayendisiti akawanda vanodavira kuti chinokosha anokiyinura zvakavanzika paumbwe yose maumbirwo nzvimbo zvakatipoteredza vanovanza vatorwa zvinhu izvi. Chero nyika diki (asteroid) achiumbwa somugumisiro zviitiko zvinoshamisa - kwakabva renzou.

Kutaura zvazviri, zvose izvi mitumbi yokudenga ndiyo zvigadzirwa uye anyerere zvapupu rose dzinotevedzana yepasi pose njodzi zvikuru simba kuti zvakazoita kuti paumbwe dzedu zvakajeka uye akatsiga yemapuraneti hurongwa. Chero nyika duku - munhu werudzii sahwira ari unopfuurira zvakaitika muchikamu chino Veselennoy anenge mana uye makore mabhiriyoni nehafu apfuura.

kusiyana kwavo, zvichienzaniswa vapfumbamwe nemapuraneti makuru kutenderera zuva, ari kuti asteroids, nemhaka yavo duku kukura uye makuru kure nyeredzi, kunge inini duku zvikuru shanduka kuchinja. Nemamwe mashoko, aumba kubva chete zvinhu sezvo vamwe midziyo yedu yemapuraneti ezvinhu, asteroids vachiri kuchengetedza uchapupu yekare Nguva Disaster Great.

mapuraneti Minor yose zuva nenyika dzinotenderera pariri - chete zvisikwa mariri kuti ano nesayenzi zvidzidzo nenzira mbiri - achishandisa yezvenyeredzi uye unmanned chitundumusere-musere, uyewo zvakananga mumarabhoritari Panyika. Munenge zvose Muzviitiko, kana zvichibvira kuziva chaiyo trajectory pakati ari meteorite, zvinoitika kuti akauya redu kubva yakasiyana nzvimbo iri foreseeable chikamu wezvose - the asteroid bhandi, izvo analogue haisati dzakaonekwa mune chero rakavhurika yemapuraneti hurongwa.

Hapana mubvunzo kuti chero meteorite uye kadiki - muviri une zvachose chete mavambo uye sezvamunoita. In kakawanda kacho, kana asteroid iri kufamba zvikuru elliptical nzira (ndiro kazhinji yo kwavari), achiyambuka muchadenga paNyika, zvishoma nyika ine zvose mikana kupinda yezvirwere uye pasi pakutsvakurudza kwazvo. Chii chingataurwa pamusoro mumwe "vagari" ari renzou. Ndiyo zvinokosha Mapuraneti diki kunyika nesayenzi.

Yunifomu hunhu meteorites uye asteroids chaizvo anowedzera yaaizova kudzidza zvekare. Nokuva ruzivo pamusoro mapuraneti diki, vakawana nehwendefa nzira, mashoko zvidzidzo pamusoro meteorites, unogona kuwana mhinduro mibvunzo inoverengeka cosmological. Zvikurukuru, kugadzirisa dambudziko rakadai unokosha sezvo mavambo asteroid mhete. Zvimwe rimwe zuva vachawanikwa mhinduro yomubvunzo wokuti: "Pane panzvimbo kujairika bhandi zvimedu guru puraneti zviri yepasi pose dambudziko akanga afa, achisiya mamiriyoni nezvimedu? Kana chete mugumisiro kurwadziswa duku mitumbi yokudenga iri nedanho inotungamirwa wedu yemapuraneti ezvinhu? "

Asi kukosha mapuraneti zviduku kwete chete. Inowanikwa meteorites dzakakwirira samolecular uremu Organic yeimwe uye vanonzi "zvakarongwa zvinhu", iro masayendisiti akawanda vanodavira zvasara extraterrestrial zvipenyu, akaisa pamberi ano nyaya sayenzi dzakadai Kushanduka chaivo zvipenyu zviri hwaiitwa muchadenga. Kuti akajekesa mavambo uye kukura upenyu Panyika. Zvinogoneka kuti kudzidza meteorites nemapuraneti diki kuti kugadzirisa izvi nyaya zvikuru kuti vanhu.
