Ukuhamba komhlaba: ujikelezo, uguqulo, ukuvela kunye nenutation

iintshukumo zomhlaba

Xa sithetha ngokuhamba koMhlaba ngaphakathi kwethu ISistema Solar Ukujikeleza kunye neentshukumo zokuguqulela kuthi qatha engqondweni. Zezona zimbini iintshukumo ezaziwayo. Enye yazo sisizathu sokuba kukho imini nobusuku kunye nezinye izizathu zokuba kukho amaxesha onyaka. Kodwa ezi ntshukumo ayizizo zodwa ezikhoyo. Kukho nezinye iintshukumo ezibalulekileyo kwaye ezingaziwayo njenge Yintshukumo yokuhamba kunye nokuhamba kwangaphambili.

Kule nqaku siza kuthetha ngeentshukumo ezine iplanethi yethu ejikeleze iLanga kunye nokubaluleka kwazo. Ngaba uyafuna ukwazi ngakumbi ngayo? Kufuneka uqhubeke ufunda.

Isindululo sokujikeleza

ukujikeleza okujikelezayo

Le yeyona ntshukumo yaziwayo kunye noguqulelo. Nangona kunjalo, ngokuqinisekileyo kukho izinto ezibalulekileyo ongazi malunga noku. Kodwa ayinamsebenzi, kuba sizakuhamba sonke. Siqala ngokuchaza ukuba yintoni le ntshukumo. Yijikelezo uMhlaba onawo kwii-axis zawo kwicala laseNtshona okanye laseMpuma. Ithathelwa ingqalelo njenge-anti-clockwise. Umhlaba uyajikeleza ngokwawo kwaye uthathe umndilili weeyure ezingama-23, imizuzu engama-56 kunye nemizuzwana emi-4.

Njengoko ubona, ngenxa yale ntshukumo yokujikeleza kukho imini nobusuku. Oku kwenzeka kuba iLanga likwindawo emiselweyo kwaye likhanyisa kuphela ubuso boMhlaba obuphambi kwawo. Icandelo elichaseneyo liya kuba mnyama kwaye kuya kuba sebusuku. Esi siphumo sinokubonwa nasemini, sijonga izithunzi emva kwexesha lomsebenzi. Singayiqonda indlela uMhlaba xa ushukuma ubangela ukuba izithunzi zibekho kwenye indawo.

Esinye isiphumo sale ntshukumo ibaluleke kakhulu yokujikeleza kukudalwa komhlaba womazibuthe. Ngombulelo kule ntsimi yemagnethi sinokuba nobomi eMhlabeni kunye nokukhuselwa okuqhubekayo kwimisebe evela kumoya welanga. Ikwavumela ubomi eMhlabeni ukuba butho emoyeni.

Ukuba sithathela ingqalelo imeko kwindawo nganye yomhlaba, isantya esijikeleza ngaso asifani macala onke. Ukuba silinganisela isantya esivela kwiikhweyitha okanye ezipalini siyakwahluka. Kwikhweyitha kuya kufuneka ihambe umgama omde ukuvula i-axis yayo kwaye iya kuhamba ngesantya se-1600 km / h. Ukuba sikhetha indawo kwinqanaba lama-45 degrees kumantla, singabona ukuba ijikeleza kwi-1073 km / h.

Intshukumo yoToliko

ukuhamba komhlaba

Siyaqhubeka nokuhlalutya intshukumo yesibini entsonkothileyo yoMhlaba. Yintshukumo uMhlaba onayo equka ukwenza ujikelo kumjikelezo wawo ujikeleze iLanga. Lo mjikelo uchaza intshukumo ye-elliptical kwaye uyenza ukuba isondele eLangeni kwaye ngamanye amaxesha kude kude.

Kukholelwa ukuba ngexesha iinyanga zasehlotyeni zishushu kuba iplanethi isondele kwiLanga kwaye ikude ebusika. Yinto ehambelanayo ukucinga ngayo, kuba ukuba sikude, ubushushu obuncinci buya kusifikelela kunokuba sikufutshane. Nangona kunjalo, kuchasene kakhulu. Ehlotyeni sikude nelanga kunasebusika. Yintoni egqiba ukuba ukulandelelana kwamaxesha awukho umgama ukusuka eMhlabeni ngokubhekisele kwiLanga kodwa kukuthambekela kwemitha yelanga. Ebusika, imitha yelanga yabetha iplanethi yethu ngendlela ethambekele ngakumbi kwaye ehlotyeni iyafana. Yiyo loo nto kukho iiyure ezininzi zokukhanya kwelanga ehlotyeni kunye nobushushu obungakumbi.

Kuthatha uMhlaba iintsuku ezingama-365, iiyure ezi-5, imizuzu engama-48 kunye nemizuzwana engama-45 ukwenza inguqu epheleleyo kwi-axis yayo yokuguqulela. Ke ngoko, rhoqo emva kweminyaka emine siba nonyaka wokutsiba apho uFebruwari anosuku olunye ngaphezulu. Oku kwenzelwa ukulungelelanisa iishedyuli kwaye zihlala zigcinekile.

Umjikelezo woMhlaba malunga neLanga unomjikelezo weekhilomitha ezingama-938 ezigidi kwaye ugcinwe kumgama ophakathi kwe-150 km ukusuka kuwo. Isantya esihamba ngaso si-000 km / h. Ngaphandle kwesantya esikhulu, asiwuxabisi umbulelo womxhuzulane woMhlaba.

I-Aphelion kunye ne-perihelion

I-aphelion kunye ne-perihelion

Indlela eyenziwa yiplanethi yethu phambi kwelanga ibizwa ngokuba yi-Ecliptic kwaye idlula ikhweyitha ekuqaleni kwentwasahlobo nasekwindla. Bayabizwa iiquinoxes. Kule ndawo, imini nobusuku zihlala ngokufanayo. Kwezona ndawo zikude ze-ecliptic esizifumanayo Ihlobo lasehlotyeni kunye ebusika. Ngethuba lala manqaku, imini inde kwaye ubusuku bufutshane (kwihlobo lasehlotyeni) kwaye ubusuku bude ngolona suku lufutshane (ebusika solstice). Ngeli nqanaba, imitha yelanga iwela ngokuthe nkqo kwenye ye-hemispheres, iyifudumeze ngakumbi. Yiyo loo nto, ngelixa emantla e-hemisphere kusebusika emazantsi ihlobo kwaye ngokuchaseneyo.

Ukuguqulelwa koMhlaba kwiLanga kunomzuzu xa ukude ekuthiwa yiAphelion kwaye kwenzeka ngenyanga kaJulayi. Ngokuchasene noko, eyona ndawo ikufutshane yoMhlaba kwiLanga yi-perihelion kwaye yenzeka ngenyanga kaJanuwari.

Ukuhamba kwangaphambili

phambi komhlaba

Lutshintsho olucothayo noluthe chu uMhlaba onawo kuqhelwaniso lwe-axis yokujikeleza. Le ntshukumo ibizwa ngokuba yimvume yoMhlaba kwaye ibangelwe ngumzuzu wamandla owenziwa yinkqubo yoMhlaba-yeLanga. Le ntshukumo ichaphazela ngokuthe ngqo ukuthanda kwelanga ukufikelela emhlabeni. Okwangoku le axis ithambekele kwiidigri ezingama-23,43.

Oku kusixelela ukuba i-axis yoMhlaba yokujikeleza ayisoloko ikhomba kwinkwenkwezi enye (Pole), kodwa ijikeleza ngokwewotshi, ibangela ukuba uMhlaba uhambe intshukumo efana naleyo ijikelezayo ngaphezulu. Ukujika okupheleleyo kwi-axis kwangaphambili kuthatha malunga neminyaka engama-25.700, ke ayisiyonto iyancomeka kwinqanaba lomntu. Nangona kunjalo, ukuba silinganisela nge Ixesha lejoloji siyabona ukuba inokubaluleka okukhulu kumaxesha e- glaciation.

Ukuhamba kwesondlo

isondlo

Le yintshukumo yokugqibela enkulu esinayo kwiplanethi yethu. Yintshukumo encinci nengaqhelekanga eyenzeka kwi-axis yokujikeleza kwazo zonke izinto ezilinganayo ezijikeleza kwi-axis yayo. Thatha iigyros kunye nokujikeleza okuphezulu, umzekelo.

Ukuba sihlalutya uMhlaba, le ntshukumo ye-nutation kukususwa kwamaxesha e-axis yokujikeleza ujikeleze indawo yayo yomndilili kwibala lasezulwini. Le ntshukumo yenzeka e unobangela wamandla obangelwa ngumxhuzulane woMhlaba kunye nomtsalane phakathi kweNyanga, iLanga kunye noMhlaba.

Olu jiko lincinci lwe-axis yomhlaba lwenzeka ngenxa ye-equatorial bulge kunye nomtsalane wenyanga. Ixesha le-nutation li-18 iminyaka.

Ndiyathemba ukuba ngolu lwazi unokukuqonda ngcono ukuhamba kweplanethi yethu.
