Ukuze amaplanethi eliwumhlaba yizo iplanethi? izici Jikelele amaplanethi eliwumhlaba

I isimiso sonozungezilanga - itholakala kuphela cwaningo eqondile isakhiwo amaplanethi. Imininingwane etholwe ngesisekelo ucwaningo kule ndawo isikhala, ezisetshenziswa ososayensi ukuqonda izinqubo ezenzeka endaweni yonke. Benza-ke kungenzeka ukuba baqonde indlela ohlelweni lwethu yavela efana ke, onjani ikusasa sonke.

Ukwahlukanisa amaplanethi yesimiso sonozungezilanga

Ucwaningo baye bavumela akhona ukuze uhlukanise amaplanethi yesimiso sonozungezilanga. Ayehlukaniswe zibe izinhlobo ezimbili: Umhlaba-kanye negesi imidondoshiya. Ukuze amaplanethi eliwumhlaba kukhona Mercury, Venus, uMhlaba, Mars. Negesi imidondoshiya - kuyinto Jupiter, Saturn, i-Uranus ne-Neptune. Pluto ngo-2006 wathola isimo iplanethi ezimfushane, futhi kungokwalabo Kuiper ibhande izinto, ezahlukene izici zayo kusukela abameleli kokubili kula maqembu.

Izimpawu amaplanethi eliwumhlaba

Uhlobo ngalunye has iqoqo izici ezihambisana isakhiwo sangaphakathi kanye nokusungulwa. Ephakeme ukuminyana isilinganiso nokudlanga idwala nensimbi kuwo wonke amazinga - izimfanelo main ukuthi ukuhlukanisa amaplanethi eliwumhlaba. Imidondoshiya Ngokuphambene, abe ongaphakeme ingxenye ukuminyana futhi ngokuyinhloko amagesi.

Zonke amaplanethi ezine abe Sakhiwo sangekhatsi efanayo: uqweqwe okuqinile Yisiphuku viscous, esigubuzele ekujuleni kwenhliziyo. isakhiwo Core, esikhundleni salokho, ihlukaniswe yaba amazinga ezimbili: core Liquid futhi eliqinile. Izingxenye ezisemqoka ke - kuba nickel nensimbi. Isiphuku ihlukile predominance core of Silicon oxides kanye manganese.

Osayizi amaplanethi yesimiso sonozungezilanga ezihlobene eliwumhlaba, kwasakazwa ngendlela (kusuka phansi kuya phezulu): Mercury, Mars, Venus, uMhlaba.

isikhwama somoya

amaplanethi Earth-like kakade kusaqalwa lasungulwa esasikuyo manje nayo yayibiyelwe isimo. Ekuqaleni kwalo elanqoba ngezithako zawo -carbon dioxide. Shintsha isimo jikelele, zaba negalelo ukuvela ukuphila. Ukuze amaplanethi eliwumhlaba nemizimba cosmic ngakho, lizungezwe emkhathini. Nokho, phakathi kwabo kukhona umuntu oselahle ikhava yakhe emoyeni. Lokhu Mercury, mass zazo ayivunyelwe silondoloze emoyeni eyinhloko.

I abaseduze to the Sun.

Emincane kakhulu iplanethi eliwumhlaba kuyinto Mercury. Ucwaningo lwakhe uye olwathi ukuthiya iseduze ilanga. Kusukela ekuqaleni isikhala yobudala idatha emayelana Mercury atholwa kuphela kusuka izimoto ezimbili: "Mariner-10" futhi "Isithunywa". Kususelwa kubo, sakwazi dala imephu zezwe futhi sibone ezinye zezici zalo.

Mercury ngempela ukuqaphela komncane kunabo iplanethi yasemhlabeni; engaba kancane esingaphansi kuka 2.5 ayizinkulungwane amakhilomitha. inhlanganiso salo eduze eMhlabeni. Isilinganiso sale index ubukhulu kunikeza isizathu sokukholelwa ukuthi le planethi siqukethe kakhulu metal.

ukunyakaza Mercury sika has eziningi izici. orbit kakhulu side: at ibanga isakhomba ilanga izikhathi ezingaphezu kuka-1.5 ngaphandle eliseduze. Omunye revolution emhlabeni inkanyezi iplanethi izenza mayelana 88 Umhlaba izinsuku. Ngakho ngonyaka Mercury has isikhathi niguquke axis awo, ingxenye kuphela okuningi. "Ukuziphatha" okunjalo akuyona ejwayelekile kwamanye amaplanethi zesimiso sonozungezilanga. Kucatshangwa Ukwehla ekuqaleni ukunyakaza ngokushesha kwabangelwa ithonya olwandle kwelanga.

Beautiful nelesabekayo

Ukuze amaplanethi eliwumhlaba kukhona kokubili emizimbeni ngekufana nekwehluka kwato cosmic. Okucishe isakhiwo, zonke zibe izici ezenza akunakwenzeka ukudida. I eziseduze Sun Mercury akuyona iplanethi ezishisayo. Lize has izigaba, njalo embozwe iqhwa. Venus, olandelayo useduze inkanyezi, libhekene okushisa aphakeme.

Sekuyisikhathi eside ogama lakhe behlonipha unkulunkulukazi wothando iplanethi kwaba nembangi isikhala letigcogcwe ngaphambilini efanelekayo ukuphila. Nokho, izimishini ngowokuqala Venus baye waphikisa lo mbono. Ingqikithi yalo iplanethi kweqiniso efihla esimweni obukhulu eyakhiwa carbon dioxide futhi nitrogen. Lokhu isikhwama somoya kunomthelela Isivuvu. Ngenxa yalokho, ngo-izinga lokushisa kwamanzi ifinyelela 475 ° C. Lapha, Ngakho-ke, ngeke kube ukuphila.

I ngobukhulu kanye nebanga elivela iplanethi ilanga has eziningi izici. Venus - iphuzu bhá esibhakabhakeni ebusuku ngemva Moon. orbit cishe umbuthano ephelele. Babalelwa ku-axis awo ihamba kusukela empumalanga kuya entshonalanga. Lena akuyona into ejwayelekile iningi amaplanethi. Revolution uzungeza ilanga elizenzayo 224,7 izinsuku Earth, nasemaceleni eksisi - I-243, okungukuthi ngonyaka emifushane kunosuku lapha.

Rock Okwesithathu Kusukela Welanga

Umhlaba uhlukile ngezindlela eziningi. Itholakala okubizwa ngokuthi habitable zone, lapho imisebe yelanga abakwazi ukuvula kobuso ehlane, kodwa efudumele ngokwanele ukuthi iplanethi engamboziwe nge ice. Kancane kancane kuka 80% of the surface kuthatha ulwandle, ukwakha ndawonye ngemifula namachibi, le hydrosphere, engekho kwamanye amaplanethi yesimiso sonozungezilanga.

Umhlaba kumiswa emkhathini ekhethekile ehlanganisa ngokuyisisekelo of nitrogen ne-oxygen nomthelela ekuthuthukiseni zokuphila. Ngokwandisa lokuhlushwa-mpilo ka ungqimba lwe-ozone kwamiswa, okuyinto ndawonye ngamandla kazibuthe ivikela iplanethi emiphumeleni elimazayo emisebeni yelanga.

Okuwukuphela satellite Zomhlaba

Inyanga has ngempela kungazithinta kakhulu eMhlabeni. Iplanethi yethu eseke umngane zemvelo cishe ngokushesha ngemva kokuba lasungulwa. Umsuka wegama Moon kuseyimpicabadala, nakuba kulesi sici kukhona imibono eyayisinesikhathi eziningana ozwakalayo. I-satellite has kuzinze enyakazayo ukutsheka eMhlabeni, futhi kubambezela iplanethi. Ngenxa yalokho, zonke izinsuku entsha iba yinde. I Ukwehla - phetho ithonya olwandle zenyanga, ungamandla kubangela namagagasi olwandle.

Iplanethi Ebomvu

Lapho ebuzwa ukuthi yini amaplanethi eliwumhlaba abangu wafunda emva engcono, njalo impendulo yethu ocacile: Mars. Ngenxa ubunjalo indawo nesimo sezulu Venus futhi Mercury wafunda kancane kakhulu.

Uma siqhathanisa osayizi amaplanethi yesimiso sonozungezilanga, Mars ivuliwe endaweni yesikhombisa ohlwini. Ubukhulu bayo - 6800 km, futhi isisindo 10.7% we ipharamitha efanayo ngaphezu komhlaba.

On kwale planethi ebomvu umoya rarefied kakhulu. Indawo yayo embozwe asemigodini, njengoba ungabona izintabamlilo ezigodini nasezintabeni glacial yiqhwa. Mars has iziphuphutheki amabili. I eziseduze iplanethi - Phobos - kancane kancane futhi ngeke esikhathini esizayo yesisindo Mars ngobugebengu. Ukuze Deymos Kunalokho, it libhekene ukususwa kancane.

Umqondo benethuba lokuphila on Mars kade baba khona eminyakeni engaphezu kweyikhulu. Ucwaningo lwamuva olwenziwa ngo-2012, wathola ku kwale planethi ebomvu izinto eziphilayo. Kuye kwasikiselwa ukuthi udaba eziphilayo phezu ungase ulethe rover Earth. Nokho, ucwaningo luye waqinisekisa umsuka imfuyo; lwaluvelaphi - planethi ebomvu uqobo. Nokho, isiphetho ocacile mayelana nokwenzeka empilweni on Mars ngaphandle ucwaningo olwengeziwe kungenziwa.

Ukuze amaplanethi eliwumhlaba esisondelene nabo izinto cosmic ngendawo. Futhi ngenxa yokuthi bayaqabukela zingcono enhle eyaziwa kakhulu. Izazi zezinkanyezi ziye kakade wathola exoplanets eziningana, mhlawumbe futhi ezihlobene zalolu hlobo. Yiqiniso, wonke ukutholakala ucingo ngale ndlela kwandisa ithemba lokuthola ukuphila ngaphandle komthala wethu.
