How fast Umhlaba kwakwenziwa orbit. How fast uhamba umhlaba uzungeza ilanga

abaningi kakhulu ajwayelekile kithi kusuka izici ebuntwaneni zokuphila zibangelwa izinqubo isikali cosmic. Imini nobusuku, izinkathi zonyaka, isikhathi yinkathi ilanga lalingabonakali emkhathizwe, ngenxa yokuthi, kanye nesivinini ngawo Umhlaba phendula, ne izici ukuhamba kwayo emkhathini.

umugqa ngengqondo

I-axis kwanoma iyiphi iplanethi - zokucabangela design wadala for the lula incazelo motion. Uma sithola ngokwengqondo umugqa ngokusebenzisa Kuma-pole, kuzoba-eksisi eMhlabeni. Azungeza ke - omunye ukunyakaza ezimbili eziyinhloko emhlabeni.

Axis akuyona indiza ye Ecliptic (endizeni ukujikeleza Umhlaba uzungeza ilanga) 90º, futhi kuphambuka perpendicular 23º27 '. Kukholakala ukuthi le planethi uzungeza kusuka entshonalanga kuya empumalanga, okungukuthi, esiphikisa. Kubonakala kanjalo ukuhamba kwayo emhlabeni eksisi, uma ubuka kuye ku-North Pole.

ubufakazi obuqand 'ikhanda

It kwakucatshangwa ukuthi iplanethi yethu umile futhi izinkanyezi ilungiswe esibhakabhakeni, ezigxile kukho. Shiya isikhathi eside akekho wayenesithakazelo umlando ijubane ngawo Umhlaba kwakwenziwa orbit emhlabeni eksisi noma, njengoba nabo ngokwabo "-eksisi" kanye umqondo welithi "orbit" alingeni kolwazi lwesayensi kwesikhathi. Ubufakazi yokulinga Iqiniso ezinyakazayo njalo umhlaba emhlabeni axis awo etholwe ngo 1851 ngu-Jean Foucault. It ekugcineni uyaqiniseka zonke labo ekhulwini nesishiyagalolunye namanje bangabaza ke.

Ukuhlolwa kwenziwa e-Paris onkulunkulu, ophahleni olungaphakathi lwesakhiwo okuyinto kwaku pendulum futhi umbuthano ukwahlukana. Wahosha pendulum nge ukunyakaza omusha ngamunye sigudluke ngezigaba eziningana. Lokhu kungenzeka kuphela uma ukujikeleza iplanethi.

isivinini

Umhlaba emhlabeni axis awo uzungeza kanjani ukudla? Impendulo ocacile yalo mbuzo kunzima ngempela ukuba ngiphane ngakho, ngoba ijubane amaphuzu ezahlukene ezindawo kuyahlukahluka. I eduze endaweni yenkabazwe, ngakho ngenhla. Emkhakheni ukubaluleka isivinini Italy, isibonelo, balinganiselwa ku 1,200 km / h. Ngokwesilinganiso, iplanethi kuyalinqoba 15º ngehora.

Ngesivinini Ukujikeleza eMhlabeni ixhunyaniswe ubude kosuku. Ubude besikhathi okuyiwona iplanethi yethu ujikeleza kanye mayelana-eksisi kuchazwe izindlela ezimbili. Ukuze ubone ukuthi inkanyezi okuthiwa noma usuku sidereal njengoba uhlelo inkomba ukhethe enye kunelanga inkanyezi. Uthatha amahora 23, imizuzu 56 no-4 imizuzwana. Uma kuqalwa kuthathwe inkanyezi yethu, ngosuku libizwa welanga. Inani wabo amahora angu-24 ngokwesilinganiso. It kuyahlukahluka kancane kuye kule planethi isikhundla isihlobo ukuba angakuboni ukukhanya, esithinta ijubane azungeza eksisi futhi ngesivinini ngawo Umhlaba ihamba ngaphakathi wo orbit.

sizungeze inkaba

Eyesibili ukunyakaza obaluleke kunayo yonke iplanethi - kuyinto "spin" yayo phezu orbit. ukunyakaza njalo e trajectory kancane side obuzwiwa abantu ngokuvamile ushintsho zonyaka. Ijubane ngawo Umhlaba ihamba phakathi Sun, uzwakalise kithi kwasekuqaleni ngezilinganiso zesikhathi nesilinganiso: omunye ithuba uthatha izinsuku ezingu-365 5:00 imizuzu 48 amasekhondi 46, okungukuthi, ngonyaka yezinkanyezi. Lesi sibalo esiqondile kuchaza ngokusobala ukuthi kungani njalo ngemva kweminyaka emine ngo-February, usuku ezengeziwe. Limelela lemali enqwabelene ngalesi sikhathi amahora ezingafakwanga ku wathola izinsuku ezingu-365 zonyaka.

Izici endleleni

Njengoba sekushiwo, izinto ijubane ngawo Umhlaba ihamba nomjikelezo wawo, ngenxa izici yokugcina. Trajectory of the iplanethi iyahluka kwenye umbuthano ephelele, it is kancane enwetshiwe. Ngenxa yalokho, i-Earth eduze inkanyiso ke kuwo. Lapho iplanethi kanye Sun sihlukanisa ibanga okungenani, lokhu isimo libizwa perihelion. Ibanga esiphezulu okuhambelana aphelion. Eyokuqala uwela ngo-January 3, kwesibili - ku 5 Julayi. Futhi iphuzu ngalinye kulawa ngamunye umbuzo othi: "Ngezinye yini ukukala Umhlaba uzungeza emzileni wawo?" - has impendulo yalo. Ukuze aphelion kuyinto 29,27 km / s, ngoba perihelion - 30,27 km / s.

Ubude usuku

Ijubane ngawo Umhlaba kwakwenziwa umzila wokuzungeza kwalo, futhi wonke ukunyakaza amaplanethi azungeza ilanga abe imiphumela eminingi emibi ngenxa ukuthi ukucacisa umehluko wemisindo nemiqondo yamagama amaningi yezimpilo zethu. Ngokwesibonelo, lezinhlangano kuthinte isikhathi sosuku. Ilanga njalo kushintsha sisendaweni yaso ezulwini, amaphuzu shift ka kwempumalanga nentshonalanga, it is a ukuphakama kancane ezahlukene ukukhanya emkhathizwe emini. Ngenxa yalokho, ukushintsha ubude bemini nobusuku.

Lamagugu azifani kuphela ngesikhathi sokulingana kwemini nobusuku, lapho Sun kweqa yasezulwini yenkabazwe Centre. Itshekisela-eksisi ngaleyo ndlela kuyinto hlangothi sokukhanyisa emaphikweni alo kukhona sigameko wama mpo yenkabazwe. Ngesikhathi sokulingana kwemini nobusuku Vernal ewela Mashi 20-21, ekwindla - ngoSepthemba 22-23.

ngenjikalanga

Kanye ngonyaka, ngosuku iphezulu kakhulu ubude, futhi isigamu ngonyaka - okungenani. Lezi izinsuku abizwa ngokuthi ngenjikalanga. Summer uwela ngoJuni 21-22, futhi ebusika - ngo-December 21-22. Esimweni sokuqala, iplanethi yethu ngakho elise mayelana Inkanyiso amaphethelo angasenyakatho aleli eksisi sibheke endaweni kwelanga. Ngenxa yalokho, imisebe iwe wama mpo Tropic of Cancer bayigubungele yonke indawo ye-Arctic Circle. ENingizimu Nenkabazwe, ngenkathi, Ngakolunye uhlangothi, ilanga imisebe ukufinyelela indawo ephakathi yenkabazwe kanye Ne-Arctic Circle.

Ebusika ngenjikalanga izenzakalo zenzeka ngendlela efanayo, kuphela Nenkabazwe inkinobho izindima: esikhanyayo eSouth Pole.

Izinkathi zonyaka

isikhundla Orbital asithinti nje kuphela ijubane ngawo Umhlaba ihamba ilanga. Ngenxa yalokho, ukushintsha ibanga ukuzihlukanisa ilanga, kanye ukuthambekela ahlangene iplanethi lumelele unyaka Ukuboshelwa basakaza emisebeni yelanga. Futhi lokhu, esikhundleni salokho, kubangela ukushintsha kwezinkathi zonyaka. Ngaphezu kwalokho, isikhathi ebusika kanye nasehlobo semester lihlukile: okokuqala izinsuku 179, kanti eyesibili - 186. Ngalokhu Imiphumela lokungafani wonke efanayo enyakazayo-eksisi ngemva kwendiza ye Ecliptic.

ibhande-ukukhanya

Ejikeleza Umhlaba ngaphakathi wo orbit futhi unenye umphumela. Le nhlangano yenkolo yokulwela yonyaka kubangela ushintsho ekhomba lapho ilanga lingakhona lalingabonakali emkhathizwe, lapho iplanethi kwakhiwa okukhanyisa esishintshashintshayo:

• Hot elisoGwini 40% of the Earth phakathi Wik naseNorthern Tropic. Njengoba leli gama lisikisela, lapha kufika ukushisa kakhulu.

• Ziyisivikelo Maphakathi - phakathi kwe-Arctic Circle futhi ezishisayo - zinezikhathi ushintsho evelele zezinkathi zonyaka.

• indawo elimhlophe itholakala ngenhla kwe-Arctic Circle, abe lokushisa ongaphakeme unyaka wonke.

achaza ukuhamba kwamaplanethi sisonke, ngokukhethekile, ijubane ngawo Umhlaba kwakwenziwa kanye emzileni, kanye nethonya kwezinye izinqubo. Phakathi kwabo, imifula, zonyaka, isigqi ezithile zokuphila phakathi kwezitshalo, izilwane kanye nabantu. Ngaphezu kwalokho, ukujikeleza Umhlaba ngenxa umphumela wawo ukukhanya kanye lokushisa kwamanzi kuthinta emisebenzini yezolimo.

Namuhla yilokhu isivinini eMhlabeni ukujikeleza, yini ibanga lalo ukusuka Sun, kanye nezinye izici ezihambisana nalo ukunyakaza amaplanethi, wafunda esikoleni. Nokho, uma ucabanga ngakho, zisobala ngempela. Lapho umcabango onjalo efika engqondweni, ngifuna ukubonga ngobuqotho ososayensi nabacwaningi abaningi abakhuluphele kakhulu ngoba nje kwengqondo yayo into engavamile anama imithetho zokuphila cosmic Zomhlaba, ukuchaza kubo bese kukhombisa nokuchaza ukuthi lonke izwe.
