Le izijikelezi inkulu kunye nentshukumo zabo. Asteroids System Solar

Asteroids okanye izijikelezi-langa ezincinane, kakhulu obuphantsi imilinganiso zabo imizimba enjalo wezijikelezi, njenge Earth, Venus nkqu Mercury. Noko ke, abanako kuqwalaselwa "abemi" yinxalenye iqhekeza lethu le Galaxy.

main ibhanti

Asteroids nelanga ekugxilwe kwimimandla emininzi. Eyona onomtsalane zazo zifumaneka phakathi umzila iMars Jupiter. Eli qela lwemizimba ezincinane uye wabizwa engundoqo ibhanti asteroid. Mass zonke izinto zibekwe apha ngemilinganiselo space ayinamsebenzi: kuba%-4 kuphela ubunzima iNyanga kaThixo. Kunye negalelo isigqibo ngale ndlela yenza ngayo izijikelezi inkulu. Yaye intshukumo yayo, kunye nokuhamba kunezixhobo ezincinane, kwakunye parameters ezifana ekwakhiweni, ifomu kunye imvelaphi, kuye kwatsala ingqalelo ngeenkwenkwezi kwinkulungwane XIX ekuqaleni: Ceres, ngaphambili ingqalelo eli litye inkulu, kwaye ngoku kungayanyaniswa inani kwiiplanethi ezincinanana, yavulwa kuqala ngoJanuwari 1801.

ngaphaya Neptune

I Kuiper ibhanti, Horta ilifu kwaye saa idiskhi ziye ziqwalaselwe kwaye bafunda njengeendawo apho kukho inani elikhulu ezincinane imizimba yasezulwini kamva. Eyokuqala kwezi ime ngaphaya komzila kweneptune. Kuye kwavulwa kuphela ngo-1992. Abaphandi baqikelela ukuba Kuiper Belt kakhulu elide ngakumbi ezibanzi ngaphezu kokuba ukuyilwa efanayo phakathi iMars Jupiter. imizimba encinane apha ezahlukileyo eziphambili izinto ibhanti ukubunjwa: methane, ammonia kunye namanzi busa rock kunye nentsimbi, "abahlali" uphawu Belt izijikelezi.

Clouds ubukho Horta namhlanje esiqinisekisiweyo, nangona kunjalo , lo mbono iyahambelana ezininzi mibono echaza elanga kwinkqubo. Wavele ilifu Orta, leyo yeyona ndawo ungqukuva ime ngaphaya komzila iiplanethi kumgama omalunga kukukhanya nyaka- ukusuka elangeni. Nazi izinto isithuba ubunjwe ammonia, methane kunye ice namanzi.

Ummandla we disc saa esilala kunye eziliqela nebhanti Kuiper. Izazinzulu abayazi imvelaphi yayo. Lubeke Kwakhona izinto eziquka iintlobo ezahlukeneyo ngumkhenkce.

Thelekisa asteroid enomsila

Ukuze ufumane ulwazi oluchanileyo mba kufuneka exutywe ngeengongoma ezimbini ngeenkwenkwezi: "comet" yaye "Asteroid". kwakungekho ukuqiniseka ukuba somahluko kwezi zibonelelo de kwango-2006. E General Assembly of IAU kunyaka wathi enomsila kunye neempawu ke, ilitye zigxile ethile, kuvumela ngaphezulu okanye ngaphantsi ngokuthembekileyo wathi wonke umzimba yasezulwini kudidi ethile.

Enomsila - into ihamba kwindawo orbit evuthelweyo kakhulu. Xa besondela ilanga ngenxa sublimation komkhenkce, zibekwe kufutshane kumphezulu womhlaba, kusekwe nonomgca lowo - ilifu uthuli kunye negesi, nto leyo eyandisa njengoko kunciphiso umgama phakathi kwento kunye yesikhanyiso kwaye soloko ilandelwa yi ukuyilwa i "Yibambe ngomsila".

Asteroids isiqaqa awakhi kunye jikelele babe orbit kangako evuthelweyo. Abo iqhubeka trajectories ezifanayo ezinomsila zithathwa ekuthiwa-umphakathi ezinomsila extinct (enomsila ekuthiwa izinto zibhangile balahlekelwe zonke izinto eguqukayo kwaye ezizo ngoko umntu).

Le izijikelezi inkulu yaye intshukumo yayo

Ngokwenene enkulu kwimigangatho isithuba izinto ibhanti engundoqo asteroid lincinane kakhulu. Uninzi ubunzima imizimba iphakathi Jupiter noMars, ebangela ezine into - kodwa Ceres, UVesta, nguPallas kunye gig. Okokuqala ngo-2006 ingqalelo eli litye inkulu; ke wanikwa iwonga yiplanethi encinane. Ceres - umzimba kakhulu setyhula ububanzi of 1000 km. ubunzima bayo-32% yabo ubunzima lilonke ezaziwayo iziza bhanti.

Eyona nto inkulu emva Ceres yi UVesta. Kubungakanani eli litye ngaphambi kuphela palladium yayo (emva ukuqondwa Ceres, yiplanethi encinane). Pallas umahluko ukusuka ekuphumleni womelele ngokungaqhelekanga nokujikeleza axis.

Gig - yesine ubukhulu kunye nobunzima yento Main Belt. Nangona ubukhulu bayo, kwafunyaniswa izijikelezi-langa ezincinane kakhulu eziliqela kamva ezincinane. Oku kubangelwa yinto yokuba gig - into omncane.

Zonke ezi imizimba enye ixhomekeke kweLanga kwicala elinye njengoko iiplanethi, yaye musa niwele indlela sesindululo woMhlaba.

iimpawu ilawula

Le izijikelezi inkulu kwaye intshukumo yabo ngokuxhomekeke kwimithetho efanayo njengoko zihamba ngako nezinye nibhinqe ihamba ngayo imizimba efanayo. nokujikeleza yawo rhoqo ukuba zakohlwaywa, ziyabonakalaliswa iiplanethi, ingakumbi Jupiter inamandla ebalulekileyo nempembelelo omkhulu.

Kancinci emzileni ome ukutshintsha zonke izijikelezi-langa ezincinane. izijikelezi Movement thile emva exposure Jupiter akunika Bayeka emzileni. Ezi izinciphiso linokuchazwa ngokuthi libe oscillation ngeenxa zonke ezinye avareji sikhundla. Kwi ezinjalo Ibhanti nganye oscillation ichitha ukuya amakhulu eziliqela eminyaka, ngoko ke imigqaliselo ukuya kumhla alonelanga ukucacisa nokungqinisisa zilungiso theoretical component. Lilonke ke, hypothesis wezijikelezi utshintsho kuqhelekile.

Isiphumo zisuke ukubana - ukwandisa amathuba zingenzi ngozi. Ngo-2011, i-data icebisa ukuba eCeres UVesta nazo kwixesha elizayo zaye zenziwa.

Le izijikelezi inkulu neentshukumo zabo rhoqo phantsi ziyapicothwa liQela izazinzulu. Properties utshintsho zabo umzila kunye nezinye iimpawu ukukhanyiswa ezinye kwisithuba lwemilinganiselo kule data kuhlalutyo nqubo ivame extrapolated kwaye izinto ezinkulu kuno izijikelezi. movement izijikelezi ngelixa ukufunda nokusebenzisa kwisiphekepheke, eziyifaneleyo Hewana zezinto ezahlukeneyo okwethutyana. Enye Matshi 6, 2015 wakhululwa ngomhla eCeres orbit.
