Ubukhulu amaplanethi nezinye izinto zesimiso sonozungezilanga

Ihamba ilanga zasemkhathini ngobukhulu eziyisishiyagalombili - amaplanethi. Ngaphezu kwalokho Earth ku solar system namaplanethi khona ezifana Mercury - esiseduzane inkanyiso, Venus - iplanethi yesibili ukusuka elangeni, Mars, Saturn, i-Jupiter, Neptune, Uranus. Lona oda amaplanethi. Ngaphambili isibaluli amaplanethi Pluto, kodwa kusukela ngo-2006 into isikhala ilahlekelwe simo sayo, futhi namuhla libizwa isigaba planetoids, amaplanethi ezincane. Cishe zonke izinto isikhala kungabonakala esibhakabhakeni ngeso lenyama, kodwa i-Uranus ne-Neptune angabona ngokusebenzisa isibonakude.

Ubukhulu amaplanethi Welanga  

Mayelana amaplanethi kwaziwe abantu kusukela ezikhathini zasendulo. Omakhelwane eliseduze kukhona Earth Mars Venus, ogama engaba ilingana 6052 amakhilomitha, ibanga - Uranium futhi Neptune.

Zonke izindikimba zasezulwini sonozungezilanga zihlukaniswe ngezigaba ezimbili. Esokuqala into kukodwa, noma okuthiwa amaplanethi kwangaphakathi eziseduze Sun - iyona Earth, Mars, Mercury ne Venus. Konke lezi zindikimba zasemkhathini endaweni eqinile, banalo high density, naphezu nengaphakathi bangaphakathi ketshezi. Umhlangano omkhulu kunayo yonke kuleli qembu yilona Earth.

Isigaba sesibili sihlanganisa zonke ezinye izinto, eyaziwa ngokuthi "amaplanethi amakhulukazi." Basuke etholakala Kukude Sun, amaplanethi usayizi leli qembu kakhulu bebakhulu emhlabeni. Nokho bebizwa amaplanethi yangaphandle. Ngokwesibonelo, isisindo kaJupiter ezikhathini ezingamakhulu amathathu ubukhulu Earth isisindo. Ngaphezu kwalokho, amaplanethi amakhulukazi kuhluke isakhiwo kusuka izinto yasemhlabeni; basuke ngokuyinhloko yakhiwe amagesi (hydrogen ne-helium), futhi lezi zifana nezinye izinkanyezi. Futhi abizwa ngokuthi "igesi imidondoshiya".

Osayizi amaplanethi kuthinte zabo ijubane ukuzungeza emhlabeni axis awo siqu, ubude bemini nobusuku.

Ngaphandle kwalezi zasezulwini isakhiwo kwesimiso sethu siqukethe amaplanethi satellites. Zonke amaplanethi lizungeza iziphuphutheki 54. Inyanga engumngane Zomhlaba, Mars kanye Neptune babe ezimbili satellite. Iningi iziphuphutheki of Saturn - nesikhombisa, futhi abanye babo babe ube usayizi omkhudlwana kunalokho the Moon. iziphuphutheki Abaningi Uranus futhi i-Jupiter ne-Mercury kuphela Venus bezisele zodwa.

Esinye isimiso sonozungezilanga travel udabule ubude nobubanzi imizimba ezincane ezihlukahlukene ayizinkulungwane: lezinkanyezi ezinomsila, asteroyidi, emkhathini izigidi izinhlayiya gas nothuli impahla, ama-athomu abahlakazekile izakhi zamakhemikhali ezahlukene, imifudlana zama-athomu.

Ibhande elisemkhathini elise phakathi Jupiter ne-Mars. Asteroid - a imizimba ezincane cosmic. Osayizi amaplanethi, asteroyidi lisukela emashumini ambalwa amamitha ezinkulungwaneni amakhilomitha. Elikhulu kunawo wonke kulo bayizinkulungwane Juno, uPallas, Ceres.

Ngokuvamile, wonke izindikimba zasezulwini sonozungezilanga zilingana ngenxa Luhambo kwelanga. Bonke lizungeza ukukhanya e indiza eyodwa (the Ecliptic) futhi siye ohlangothini olufanayo. Okukhishwayo kuphela ezinye lezinkanyezi ezinomsila. Cishe zonke izindikimba zasezulwini singaxoxi axis awo.

On the mass of the Sun ebangela cishe 99,80% we mass lonke zesimiso sonozungezilanga. Ungqimba esisele 99% lokucabanga igesi imidondoshiya (Saturn Jupiter). Izazi zezinkanyezi zithi usayizi uhlelo lwethu akuzona esingaphansi bhiliyoni 60,0 amakhilomitha - ukwethula libe liqhele kangaka kunzima kakhulu. Phakathi izinkanyezi ibanga kukalwa amayunithi yezinkanyezi. Omunye kahle. e. ibanga phakathi kwelanga nomhlaba (angaba yizigidi 150,0. km).

Ukuze ukucabanga esikalini we isimiso sonozungezilanga amaplanethi Ubukhulu, ungasebenzisa imodeli elandelayo, kwemigomo okuzokwenza zingancishiswa ngokushintsha izikhathi eziyinkulungwane. Ngakho, emhlabeni ububanzi ka 1.3 cm, Moon uzobe akhiwe kude kuwo of cm 30, i-Jupiter kuyoba usayizi kwangangopapamusi kanye umuntu ingafaniswa athomu. Sun ubukhulu kuyoba amamitha eyodwa nengxenye, futhi itholakala 150 amamitha away. Inkanyezi eliseduze ungaphakathi imodeli uzobe sise ibanga amakhilomitha yizinkulungwane ezingamashumi amane.
