A sezijikelezi Bajikeleza kwi circumstellar - ntoni na?

Xa isithuba, ngeenkwenkwezi baye bafumana izinto ezininzi ezahlukeneyo. Ezi iinkwenkwezi, exoplanets, amafu, izijikelezi-langa ezincinane, quasars. Ezinye zezi izinto kwindawo yazo ethile. A move kukho imizimba yasezulwini omise zabo ngeenxa zonke iinkwenkwezi?

A sezijikelezi Bajikeleza kwi circumstellar - ntoni na?

Okokuqala kufuneka ukuba siqwalasele oko kuthethwa "okuwo". Le indlela apho umzimba yasezulwini iyajikeleza. Umzekelo, i-Earth eyayisaya inkwenkwezi yethu - ilanga. Ehlabathini Earth, ke, yenza indlela yayo eNyangeni. sezijikelezi at orbit circumstellar kuba, okokuqala, umhlaba, okwesibini, ke, ilitye, kunye enomsila. imizimba ezincinci yasezulwini azithathwa yi izazi, ukusukela ukuba zifakwe kudidi kobutyobo isithuba. Ngapha koko, nokujikeleza babo ngenxa ubunzima encinane imizimba yasezulwini iya kuba iimpawu eziphambili - rhoqo. Naliphi na iqumrhu mass luya kuchaphazela isikhokelo bentshukumo lwabo - ukuya ngxi.

Kananjalo banalo Hewana orbit esiqingqiweyo se-Earth, wadalwa ngumntu. Xa uhlobo ziyafana ellipses evuthelweyo. Ingongoma abakhulu komzila a perigee, kwaye zikude - Apogee. emzimbeni ngalinye Iziko kwi orbit circumstellar ilanga edakasa kwicala elinye. Yinto sisiganeko emangalisayo inkqubo elanga, nto leyo kububungqina enye yeengcinga yemvelaphi yako. Ngokwalo mbono, inkqubo solar kuvele ilifu uthuli kunye negesi. Ukongeza amawaka iiplanethi ezincinane, izijikelezi-langa ezincinane, nokuba ihamba kwicala elinye.

Asteroids kwi Solar System

izazinzulu Asteroids ubize imizimba yasezulwini enobubanzi ngaphezu kweemitha ezingama-30. Nabo ke, ukuze babe Hewana zabo. Igama elithi "njengokuntlithwa" kwacetyiswa yi umqambi Charlzom Berni kunye ngeenkwenkwezi uWilliam iHerschel, lithetha "ngathi inkwenkwezi". Xa sigcina izijikelezi imbonakalo yazo phantse yinto enzima iinkwenkwezi. Iinkwenkwezi kwakukhangeleka amavili yigolide evuthiweyo, kunye izijikelezi ziziswa ngohlobo amanqaku yokukhanya. Okwangoku, unomdla kakhulu yenzululwazi ukuba izazi, ebizwa ngokuba yi- ibhanti asteroid. Bona omnye izinto indawo enkulu kwinkqubo elanga. Ngaphakathi inkqubo elanga ibhanti asteroid engundoqo ibekwe phakathi umzila iiplanethi iMars Jupiter.

Ezinomsila - kunye nesikhokelo imizimba yasezulwini

Yintoni enye ingafunyanwa kwi zasezulwini circumstellar umzimba Bajikeleza? Impendulo ingase ibonakale Akumangalisi, kodwa oko - enomsila. Le zasezulwini kwakhona zijikeleza kumzila zabo ngeenxa ilanga. Iguqulwe ukusuka 'unomgca "ulwimi lesiGrike elithetha" inkwenkwezi ixhonti ". Njengoko enomsila lisondela ilanga okuya kusanda, yaye isabelo sakhe luzizi uza kuncothulwa. ezinomsila Bright kunokubonwa esibhakabhakeni ngeliso lenyama. Amaxesha ujikeleza ezi imizimba yasezulwini ngokujikeleze iLanga ekungabonini ukusuka kwiminyaka embalwa ukuya kangangoko eminyaka.

Xa enomsila kuthiwa kude eLangeni, oko ayibonakali Earth. A sisondela, iba ifumaneke okhangeleka kumbukeli eziqhelekileyo. Ngokuba lixesha lokuqala nezihlandlo ukujikeleza ezinomsila ngokujikeleze iLanga yafunyanwa Isazinzulu Halley ngenkulungwane XVII. Ukubukela enomsila, wafumanisa ukuba sihamba ngendlela efanayo njengoko eminye imihlaba yenkqubo elanga. Halley kwangaphambili umhla wokubuyiswa le nonomgca Emhlabeni babukeleyo. Umphengululi Ukuqikelela yakhiwe ugwetyelwe.

izazinzulu Nakhodka Ibhanti Bajikeleza inkwenkwezi ofayo

Ngo-Oktobha 2013, izazi abeyifumene isidumbu yasezulwini kwi circumstellar Bajikeleza yinkwenkwezi iqhawuka elikude. Isikhanyiso ogama G61 ebesiphe kwiqela UDema ezimhlophe kwaye lisuswe kwinkqubo elanga kumgama omalunga nezigidi 150 iminyaka elula. umzimba yasezulwini bexakeke le nkwenkwezi, kwaba Ibhanti, apho iingcali zenzululwazi zifumanise isixa esikhulu zolondolozo lwamanzi. Le lokufumanisa ukuba ngeenkwenkwezi sicinge ukuba kule nkqubo xa kungakho izijikelezi-langa kwelimiweyo efana neyethu.

Oku kunjalo yokuqala xa ngaphandle umnyele wethu iimeko ezimbini eziphambili ukuvela ubomi kwafunyanwa - kumphezulu Etsolweni lengxondorha, amanzi, nto leyo unomzimba yasezulwini Bajikeleza kwi circumstellar. Oku kubonisa ukuba xa kwakukho ubomi. Yintoni eyenza oko kuthabatha kule nkqubo - izazinzulu nga ndicinga kuphela. Uhlalutyo ofayo Ibhanti wabonisa ukuba izilingo amanzi 26%. Xa oku kufana yiplanethi encinane kwi Solar System - Ceres. Njengoko afumaneka eli litye eCeres ubunzima ekhoyo amanzi phezu kwabo likhulu kakhulu on Earth.

G61 kunye sezijikelezi Bajikeleza kwi circumstellar - impendulo ifumaneka elizayo komhlaba

Umhlaba ngokuyimfuneko iplanethi elomileyo. 0,02% kuphela ubunzima bayo yonke amanzi. Iingcali zenzululwazi zikholelwa ekubeni iilwandle zibonakele emva kokuba lisekiwe Umhlaba. Yi vekeleke, abaphandi, uMhlaba kumelana inani elikhulu izijikelezi yamanzi-rich. ezingaqondakaliyo Kuqala umzimba yasezulwini Bajikeleza kwi circumstellar, oosonzululwazi baye bafunda malunga nekamva loluntu kunokwenzeka. Bacebise ukuba emva kweminyaka 6 billion, kanye njengoko abaphandi ophambukele kufunda lowo doti lengxondorha Bajikeleza yokufa lethu ilanga, yaye uya kuza kwisigqibo sokuba umhlaba kanye nako ukuxhasa ubomi.
