Yintoni izijikelezi yaye oko kwaziwayo ngabo?

Yintoni izijikelezi-langa ezincinane? Into yokuqala ndingathanda bathi ekuthiwa-imizimba eqinileyo onamatye ukuba ngapha zisuke yelanga elliptically iindebe ezifana iiplanethi. Noko ke, izijikelezi-langa ezincinane isithuba abe ubukhulu encinci kakhulu, enyanisweni, izijikelezi-langa ngokwabo. ububanzi yabo ngokuqhelekileyo malunga kolundi zilandelayo: ukusuka emashumini ezimbalwa kweemitha ukuba amawaka eekhilomitha.

Bezibuza ukuba izijikelezi-langa ezincinane, kunye nabantu ababa kunceda ucinge phi yonke le kota, ukuba lithetha ntoni. Yena bubonakala "inkwenkwezi-like", waza wamazisa ukuba ngeenkwenkwezi ngenkulungwane XVIII ogama uWilliam iHerschel.

Enomsila kunye izijikelezi zingabonakala njengemithombo indawo kukhanya ethile, ngaphezulu okanye ngaphantsi eliqaqambileyo. Nakuba data kuluhlu ebonakalayo imizimba yasezulwini musa angakanani - zibonisa kuphela kwelanga lowo uwe phezu kwabo. Kufuneka kuqatshelwe ukuba ezinomsila zahluka izijikelezi. Okokuqala - it le inkangeleko yabo eyahlukeneyo. Enomsila lula liyabonakala by ngumongo oqaqambileyo nomsila eziveliswa lilo.

Uninzi izijikelezi-langa ezincinane, ezaziwa ukuba izazi namhlanje, ehamba phakathi umzila kaZeyus noMars kumgama omalunga 2.2-3.2 kunye. e. (oko kukuthi, iiyunithi ngeenkwenkwezi) ukusuka elangeni. Ukuza kuthi ga ngoku, oososayensi bafumene malunga nama-20 amawaka izijikelezi. Ibhaliswe kubo ekhulwini amahlanu kuphela. Yintoni na izijikelezi lokubhalisa? Lo mzimba wasezulwini, nto leyo unikwe inombolo, yaye ngamanye amaxesha namagama abo. nokujikeleza zabo zilungiselelwe ngokuchanileyo phezulu kakhulu. Kufanele kuphawulwe ukuba ezi imizimba yasezulwini zidla amagama ukuba ziye zabelwa discoverers zabo. Amagama izijikelezi athathe, ngokuqhelekileyo ukusuka kwiintsomi zamaGrike.

Ngokubanzi, ukusuka nkcazelo ingentla, kucacile ukuba izijikelezi-langa ezincinane ezinjalo. Kodwa yintoni enye ekuso kubo?

Ngenxa ye data imigqaliselo kweenkwenkwezi ngokusebenzisa telescope kwafunyaniswa ulwazi olunomdla. zingatshintshwa aqaqambileyo inani elikhulu izijikelezi-langa ezincinane, kwaye ngexesha elifutshane kakhulu - oku kuthatha iintsuku eziliqela okanye iiyure eziliqela. Oosonzuluwazi kudala hypothesized ukuba ezi utshintsho ilitha ezi izijikelezi zinxulunyaniswa ukujikeleza zabo. Kufuneka kuqatshelwe ukuba zibangelwa yi - kanye yokuqala - iimilo zabo ezitenxileyo ezinokwenzeka. Kwaye imifanekiso wokuqala ezi imizimba yasezulwini (imifanekiso zithathwa ngoncedo zafakwa iziphekepheke), ukuqinisekisile mbono, kodwa wabonisa kulandelayo: umphezulu izijikelezi bemba ngokupheleleyo yimingxuma enzulu kunye yimingxuma ezinobukhulu obahlukileyo.

Eli litye likhulu bafumanisa kwisixokelelwano sethu langa, wakha wayicinga into eCeres umzimba yasezulwini, leyo malunga nobukhulu 975 x 909 km. Kodwa ukususela ngo-2006 kuye ufumene iwonga eyahlukileyo. Waza waba yiplanethi encinane. Ke namanye amabini asteroid enkulu (phantsi amagama nguPallas kunye UVesta) abe sangqa kweekhilomitha ezili-500! Kufuneka kwakhona uqaphele omnye okunika umdla. Into yokuba i-West - eli litye kuphela ukuba eneneni nibonwe ngeliso lenyama.
