Amaplanethi esimisweni sonozungezilanga

Uhlelo elanga - omunye izinhlelo eziningi kwamaplanethi emthaleni enkulu, i-Milky Way, kodwa lokho kumane nje ucishe waqonda. Ngaphandle kwayo, emthaleni kuyinto ngaphezu kwesigidi inkanyezi izinhlelo, lapho asazi lutho. ubuchwepheshe Wanamuhla ukuhlola umkhathi banikezwe ithuba lokufunda okuningi ulwazi mayelana sonozungezilanga futhi isakhiwo isakhiwo, isikhundla amaplanethi nemingcele zabo, kanye nezinye izindikimba zasezulwini, okuyizinto wakhe. Manje siyazi ukuthi phakathi kuba ilanga emhlabeni lapho amazinga ehlukene ngaphansi kwethonya amandla adonsela phansi ukushintshanisa iplanethi, kuhlanganise i-Earth. Ingxenye enkulu mass kohlelo kuyadingeka ukuze ilanga - cishe 99,866%, futhi 99% kusukela lonke mass bagxila amaplanethi amakhulukazi.

Kuqala kwakukholelwa bazitshela ukuthi 9 Amaplanethi azungeza ilanga lethu, kodwa kusukela ukususwa ohlwini amaplanethi Pluto ngo-2006, kuthathwa ngokuthi baba 8. Ngamunye wabo ayisebenzisa ngayo azungeza ilanga ngaphakathi wo orbit eqondile futhi uzungeza basesimweni esifanayo Ecliptic. Basuke evamile ngamaqembu amabili. Ngo amaplanethi lokuqala Earth-like yakhiwa ngokuyinhloko nsimbi netshe rocks kukhona Mercury, i-Earth, Venus ne-Mars. Amaplanethi leqembu esiseduzane ilanga. Mercury kanye Venus abanalo izinyanga, Mars has bobabili - Awamademo futhi Phobos uhamba emhlabeni Umhlaba njengoba Moon.

Planet neqembu lesibili abizwa ngokuthi giant amaplanethi sibonga abangelwa yisisindo esikhulu futhi ivolumu, izikhathi eziningana ephakeme ukwedlula izinto eliwumhlaba. Lawa Uranus, Saturn, i-Jupiter ne-Neptune. Bona igesi, ngokuvamile yakhiwa hydrogen ne-helium, futhi Saturn kuphela has a core okuqinile. Amaplanethi yalolu hlobo wukuthi zazo zingaphazami kukhona okuningi phambidlana eLangeni kuka abamele iqembu lokuqala. Futhi komunye umahluko okhona phakathi kwabo kuba khona inani elikhulu iziphuphutheki ngokusondelene nalezi amaplanethi. Ngokwesibonelo, i-Jupiter kuhambisana 63 iziphuphutheki eduze Saturn of 62 kanye amasongo ambalwa, i-Uranus unabo 27 ne-Neptune - 13.

Mercury esiseduzane ilanga. orbit singu-57-9 million kuphela,. Km kusukela ilanga. Emzileni Venus okuncane okwengeziwe - ukuze 108,2 izigidi ezingu Km.. Ibanga lesithathu Earth. ngendlela yakhe azungeza umzimba wasezulwini sise ibanga 149 600 000. Km ngamancozuncozu, okuyinto enhle ukuze ukuphila kuqhubeke kukhona emhlabeni. Empeleni, omunye iplanethi lonke uhlelo kuphela impilo. Mares, uma siqhathanisa nabanye izinto eliwumhlaba, ezingxenyeni ezikude kakhulu. orbit - yesine - 227 900 000 km ..

Indawo amaplanethi amakhulukazi kukhona okuningi ezikude ilanga. I oseduze kakhulu-Jupiter - esikhulu kunazo zonke wonke amaplanethi ezisesimisweni sethu sikanozungezilanga. It uzungeza kuma emzileni wesihlanu 778,6 wezigidi. Km kusukela ilanga. orbit Sixth ku 1433700000. Amakhilomitha kuthatha Saturn, okuyinto endaweni yesibili phakathi amaplanethi ngosayizi. Uranus ehamba orbit lwesikhombisa okuyinto ezikude eLangeni at 2870400000. Km. Futhi ezikude kakhulu zaleli zonke iplanethi - Neptune. orbit itholakala at ibanga 4.491.100.000. Km.

Ngo o uhle eziningi, amaplanethi yesimiso sonozungezilanga evamile ziboniswe Isikhala elilinganayo phakathi umzila wenyanga wonke amaplanethi, kodwa kubonakala ehlukile kancane empeleni. Ngokwengxenye enkulu, ibanga elibahlukanisile kwandisa yakheke nge remoteness esuka ekukhanyeni.

Ukuzungelezisa cishe wonke amaplanethi uya okuhlukile ngokwewashi ukuthi, lapho libhekwa North Pole, kodwa Venus futhi Uranus kukhona ngaphandle. Athuthela kolunye uhlangothi. Kodwa nokho ngesikhathi esifanayo Uranus esitshekile ahlangene cishe ngo-90 °, okuyinto sengathi it is ngohlangothi yayo.

Amaplanethi esimisweni sonozungezilanga kanye nesisindo yabo ngokuyinhloko nomthelela ijubane ukujikeleza wabo njengoba uzungeza ilanga. Mercury uzungeza ngokushesha kunanoma ubani - senza emhlabeni wonke kwaba khona ukuvukela ephelele ezinsukwini 88 (omhlaba). Futhi okulengayo - Neptune - ithuba lakhe edingekayo eminyakeni 165.
