Oort mtambo Kuiper lamba - kumalire a dongosolo dzuwa thupi

The Oort Mtambo - lamba Wonenedwa padziko dongosolo la zowalitsa wodzazidwa ndi asteroids ndi comets. Pakali pano, palibe zakutali silinaizindikire atha kudziwa zinthu ochepa chapatali, koma ambiri umboni umboni zikuonetsanso kuti malire kutali a dongosolo lathu dzuwa pali maphunziro ofanana. Komabe, musati kusokoneza Kuiper lamba ndi Oort mtambo. Woyamba ndi ofanana ndi lamba asteroid , kuphatikizapo ambiri mabungwe ang'onoang'ono. Iwo linatsegulidwa ndi posachedwapa, mu awiri chaka masauzande, atazindikira kuti kupitirira kanjira wa Pluto padziko dzuwa umakhudza zakuthambo, zomwe zina mwa ngakhale zazikulu kuposa dziko chinayi, koma osati onse a iwo omveka ndipo chitakonzedwa kanjira, zonse kusuntha kwake njira yodutsamo pansi zochita za mzake. Njakata: pa dzanja limodzi, izo sizikanakhala kutchedwa dziko, koma Komano, malinga ndi kukula kwa iwo amakhala akuluakulu kuposa Pluto. Ngakhale asayansi amakono kwa nthawi yoyamba mu mbiri analenga mndandanda bwino yosayambitsa kuti anakumana ndi thupi wakumwamba kuvala udindo dziko. Chifukwa, Pluto wataya udindowu. M'zaka zaposachedwapa, asayansi atulukira ambiri zinthu mu Kuiper lamba. Yaikulu ya iwo - Eris ndi Sedna.

Ndipo kodi Oort mtambo?

Ngati Kuiper lamba zinthu zimapezeka mosavuta kuti telesikopu ano, mtembo wa mtambo lakutali ku Sun pa kuwala chaka. Taonani pa mtunda mwachindunji mu telesikopu awo koma mokwanira kovuta. Choncho Astrophysics anapeza ambiri mlengalenga, ngakhale ena machitidwe nyenyezi, koma, choyamba, ndi pafupifupi Mapulaneti akuluakulu monga Jupiter, ndipo kachiwiri, iwo sanalembedwepo pa okha, koma chifukwa zotsatira yokoka pa nyenyezi ake. Komabe, Oort mtambo kwenikweni anatituma ife wambiri umboni linakhalapo. Tikuyankhula zokhudza comets amene amabwera periodicity zonse mu dongosolo la zowalitsa, monga amithenga a dera lino. Mwina chitsanzo chotchuka kwambiri Halley. The Oort mtambo dzina lake polemekeza Katswiri Dutch, amene pakati pa XX atumwi, ananeneratu anapeza ake, zochokera kuzipenya wa kuleza nthawi comets. Kudera limeneli, komanso lamba Kuiper tichipeza TNOs, amene amapatsidwa anapeka makamaka ayezi ndi methane, mpweya monoxide, cyanide wa hydrogen, ethane ndi zinthu zina. N'kutheka kuti akhoza zimayenda ndi zinthu mwala.

Magwero a dera la

astrophysicists zamakono zomwe amakhulupirira kuti Kuiper lamba, ndi Oort mtambo - ndi zotsala za zipangizo anapanga dongosolo dzuwa, koma sanali m'gulu zikuchokera aliyense dziko lina. Biliyoni zaka zisanu zapitazo, ambiri mwa zinthu chakumene m'badwo woyamba wa nyenyezi (kuti aumbike patangopita nthawi yochepa Big Bang) chifukwa yokoka ndi zaka mamiliyoni compaction anali lidzasinthidwa nyenyezi yatsopano - dzuwa. A mbali yaing'ono ya protoplanetary litayamba onsewo anasonkhana midadada yaikulu ndipo anapanga dziko lapansili. Otsala a fumbi ndi zinthu zazing'ono Nebula anaponyedwa m'mphepete mwa System Dzuwa, kupanga Kuiper lamba, ndipo kwambiri lakutali kwambiri dera la Oort mtambo.
