Oort gore uye Kuiper bhandi - muganhu zuva nenyika dzinotenderera pariri muviri

The Oort Cloud - a tsvagai Bhandi zuva nenyika dzinotenderera pariri akazara asteroids uye comets. To musi, hapana teresikopu haasati kukwanisa kuziva zvinhu zviduku zvakadai kure, asi chaizvo nemamiriro ezvinhu uchapupu hunoratidza kuti pane miganhu kure dzedu renzou pane zvakafanana dzidzo. Zvisinei, regai kunyonganisa Kuiper bhandi uye Oort gore. Rokutanga zvakare yakafanana iri asteroid bhandi , uye zvinosanganisira zvakawanda diki masangano. Chakazarurwa tichishandisa yapfuura, vari vaviri gore kuzviuru, kana zvakanga yakawanikwa kuti mhiri muchadenga kuti Pluto kuti kupota zuva dzitendererane mitumbi yokudenga, zvimwe zvacho yakatokura kupfuura repfumbamwe nyika, asi kwete vose ainyatsoona uye hauchazvidzwi muchadenga, nguva dzose kuchinja yake trajectory pasi zvinoitwa mumwe. Dilemma: rumwe rutivi, ivo aisagona kunzi nyika, asi Ukuwo, maererano noukuru avo akakura kupfuura Pluto. Nepo masayendisiti ano kokutanga munhoroondo akasika pasi zvakajeka zvinodiwa kuti vakasangana nevanhu muviri yokudenga kupfeka nyika mamiriro. Somugumisiro, Pluto hachisisina kuti chinzvimbo. Mumakore achangopfuura, masayendisiti vakawana hwakawanda zvinhu zviri Kuiper bhandi. Remasangano pavo - Eris uye Sedna.

Uye chii Oort gore?

Kana Kuiper bhandi zvinhu zviri nyore kuti materesikopu ano, muviri negore kure kubva Sun panguva chiedza-gore. Funga kure zvakananga materesikopu dzavo asi zvakakwana zvakaoma. Saka zvokuongorora nyeredzi, nyika akaziva hwakawanda mapuraneti, kunyange dzimwe nyeredzi enyika, asi, chokutanga, ndiyo nyika hombe anenge zvose kufanana Jupiter, uye chepiri havaiti kuitika voga, asi nokuda rinokweva nomugumisiro ayo nyeredzi. Zvisinei, Oort gore chaizvoizvo anotumira isu yakawanda uchapupu ivepo. Tiri kutaura comets zvinouya dzose periodicity munyika nenyika dzinotenderera pariri, senhume bhora ichi. Zvichida anozivikanwa kupfuura muenzaniso ndiye Halley. The Oort gore akanzi ari kukudzwa Dutch astrophysicist, uyo ari pakati XX remakore, vakafanotaura zvakawanikwa kwayo, kwakavakirwa zvaanorumbidza ose-refu comets. nzvimbo iyi, uyewo bhandi Kuiper une TNOs, izvo zvaizoitawo vanoumbwa zvikurukuru echando uye methane, carbon monoxide, rehydrogen cyanide, ethane uye zvimwe zvinhu. Angangove chaizvo kuti rinogona zvayaitenderera paguyo uye ibwe zvinhu.

Mabviro nokure

Modern astrophysicists vanodavira kuti Kuiper Belt, kuti Oort gore - ndizvo Zvinosara pachinopiwa zvinhu akaumba dzaro, asi havana vanobatanidzwa Zvinoumba munhu nyika. Makore anenge mashanu bhiriyoni akapfuura, vakawanda zvinhu kuti raputika chizvarwa chokutanga nyeredzi (inopfurwa nguva pfupi Big Bang) somugumisiro regiravhiti uye mamiriyoni makore compaction yakashandurwa kuva nyeredzi itsva - zuva. A duku chikamu protoplanetary dhisiki Rotating vakaungana huru zvinogumbura uye akaumba dzomuchadenga maitiro edu. Vamwe guruva uye zviduku zvinhu nebula zvaikandwa pamusoro kumucheto Solar System, achiumba Kuiper bhandi, uye zvoupenyu pamusoro Oort gore kwazvo kwazvo.
