Amaplanethi we Solar System. Izingane kanye nabantu abadala

Uhlelo elanga - kuyinto 8 zasemkhathini ezinkulu, futhi eziningi izinyanga amaplanethi, lezinkanyezi ezinomsila kanye asteroyidi. Abantu abanesifiso astronomy kusukela kudala. Khona-ke zo wazama yizinkanyezi ukunquma ezizokwehlela abantu, lokubikezela izenzakalo zesikhathi esizayo. Ngisho ne-yiso lenyama amaplanethi ayisihlanu angase, ngakho ukwakheka sonozungezilanga ngalezo zinsuku lalithé: Venus, Mercury, Mars, Saturn kanye Jupiter.

Kuphela obhekwe izibonakude, ososayensi bakwazi ukuhlola kabanzi isakhiwo kwezindikimba zasezulwini eyaziwa futhi ubone iplanethi kude futhi ezazingaziwa. Ukwethulwa isikhala esiteshini lokuqala kuvulwe imibono abantu abaningi futhi ukukhanya entsha wembula iplanethi we Solar System. Ngoba abantwana kuba lesi sihloko okuthakazelisayo nokuwusizo ngokuthi "pochemuchek" ezincane edonsela engaziwa.

Eziseduze Sun luncane ohlelweni we nendikimba ethile esemkhathini - Mercury. Sisekhona ebizwa nge- "iplanethi kokuqhathanisa", njengoba uhlangothi olulodwa ukuncibilika kwezinguzunga beshiswa degrees 300, futhi ezinye nokubusa abandayo nobumnyama. Lokhu kwenzeka ngenxa yokuthi Mercury uzungeza ilanga, ebe ngokushesha futhi kancane kakhulu kuma-axis awo. Satellites elalingazange.

Abacwaningi babenegunya elikhulu lokudlela, kodwa bahluleka ukwenza ngokuvumelana ukuhlola Venus. Leplanethi ongaqondakali zimbozwe 20-ikhilomitha, ngakho asiboni itholakala ngaphansi okuyinto esihogweni, kusukela ebusweni umzimba yasezulwini kuyinto red-hot-degrees 500. Ngenxa okuqhubekayo esigaxeni yelanga musa ukungena lapha, nokunye Venus ebumnyameni ebusa. Isibhakabhaka siqukethe carbon dioxide, i-sulphur kukhona imvula njalo nomoya ngesivinini jaha amafu.

Mars ayedumile njengoba ethandwa kakhulu le planethi sonozungezilanga. Ezinganeni, kunezindlela eziningi yesayensi amabhuku owaziwa kwekhulu elidlule, owayekholelwa ukuthi indawo lapha, futhi, kukhona ukuphila. Lokhu umzimba wasezulwini ngempela kuthi akufane nokwenzeka Umhlaba, ebusuku lapha zokugcina kancane ngaphezu kwamahora angu-24, isikhundla-eksisi kuyafana-eksisi kule planethi yethu. Kodwa ukuphila Mars Namanje hhayi bekubona, umkhathi ugcwele kwaphela kakhulu, it is ukufuthelana ngu ilanga kubi, unjalo lokushisa ingeqi 0 degrees.

Ngu amaplanethi amakhulukazi kukhona Saturn, i-Jupiter, Neptune and Uranus. Jupiter ayedumile njengoba planethi enkulu sonozungezilanga. Ezinganeni uzobe sizibuza ukuthi it is ukuphotha ngesivinini, nomkhathi wawo, amafu abonakala kuphela ngokushesha odlulayo. nendikimba ethile esemkhathini unenkambu enamandla kakhulu kazibuthe. It has 16 iziphuphutheki ezaziwayo.

Saturn siqukethe ane-helium ne-hydrogen, kuyabanda, is imimoya asheshe ezaziwayo. ezithakazelisayo kakhulu ohlelweni izindandatho ozungeza nendikimba ethile esemkhathini. Kuze kube manje, ososayensi baye ayitholakalanga izincazelo zabo, futhi ezinqwabelene imibuzo engaphezu kuka izimpendulo. It has iziphuphutheki eyaziwa 15.

Uranus ne-Neptune nazo imidondoshiya kodwa iqhwa esikhundleni igesi. Eyokuqala has a ebusweni okuyisidina kakhulu, sabuthana eduze iziphuphutheki wakhe 5. Eyesibili ungathi Umhlaba ngenxa blue ezijulile. Ngokwe isivinini somoya ancintisane Neptune bengayi akukho amaplanethi yesimiso sonozungezilanga. Ezinganeni ngisho imfihlo ukuthi lalibhekwa njengendawo iplanethi, futhi Pluto, kodwa ke kwanqunywa ukuba ngakususi kuye ohlwini bese zibalwa njengoba ethanda imizimba yemifino lasezulwini, amaplanethi kuthiwani 50.
