North Star, nendlela yokufumana i-Little Dipper kwi Big Dipper?

Ukuba ujonga emva iinkulungwane, phakathi asterisks ezininzi indawo kunokuba ibalulekileyo kuhlala yi lekroza Ursa Minor. Bonke ubungqina bubonisa ukuba uhambo wamandulo esekelwe kwindawo beenkwenkwezi kulo. Nangona ngamanye amaxesha amaFenike ukusebenzisa orienteering Big Dipper, nangona nokubengezela ephakamileyo yayo, ukuze abanike ezingachanekanga ebalulekileyo Ukumiselwa endleleni.

Indlela yokufumana Ursa Minor for ngakumbi?

Ngokucacileyo, abaninzi kuni ngokulula uya kufumana i-Big Dipper. Kuyinto ekhululekile kunye eliqaqambileyo. Ukwazi ukuba imilindo yeenyanga ezimbini apho, akukho mathandabuzo, kuya kuba kucace ukuba ukufumana indlela Ursa Minor kwi-Big Dipper. Ukuze wenze oku, kufuneka ukudibanisa engqondweni iinkwenkwezi ezimbini zokugqibela Big Dipper ukusuka leMeraka (β Big Dipper) ukuya Dubhe (α Ursa Major)), ukuqhubeka le umgca ukuya kumgama omalunga izihlandlo ezi-5 mkhulu umgama phakathi kwabo. Ngale ndlela, uya kufumana alpha (polaris) umlaza Ursa Minor.

Phambi kokuba ukwazi ukufumana indlela umlaza Ursa Minor, esazi kuphela indawo polaris, kufuneka uqonde uhlobo mzobo zenze ntoni na ukukhanya, nendlela asterisk imalunga Big Dipper. Ukuze uqonde ngokupheleleyo: ngokwamagama abo, ukuba ziyafana ngokwaneleyo kwaye bafana imilo ukhamba. Njengoko ngokuba indawo, i Dipper Little iphantse ngamahla ndinyuka indawo ngokuphathelele Big Dipper.

Ulwazi - amandla

Hlola kwimephu yeenkwenkwezi phambi kokuqala uphendlo, oko kuya kwenza kube lula uphendlo lwakho ukuba asterisk. Emva koko, qiniseka ukuba ningenakumbi ekufumanekeni iqela ogcwele ezinqwenelekayo. Ke ukuba umntu ucela ukuba ufumane indlela Dipper Little the Big Dipper, unalo ulwazi epheleleyo iifekthi ziya kuba nako ukuchaza ngokucacileyo ukuba khangela ngayo.

Kulungile, ngoku siyazi ukufumana indlela umlaza Ursa Minor. Makhe sithethe North Star ngazo ukwenza abahambi ngendlela elide kwaye nzima kunye nabahloli yexesha elidlulileyo. Nangona le nto inkwenkwezi aqaqambe esibhakabhakeni ebusuku, kodwa ibekwe kufutshane kwinxalenye esemantla yehlabathi, impazamo ayidluli 1 °. Emva kweminyaka 145 kuphela, impazamo indawo, mkhulu isidanga enye.

Kuphela emva 3200, inkwenkwezi leyo kufutshane nje kwinxalenye esemantla yehlabathi, iza Alderamin (Alpha Cephei).

"Cool" ibhere ngomsila of axis bomhlaba

North Star ayitshintshi indawo yayo, nangona ukuhamba imihla ngemihla Umhlaba ngeenxa axis yayo kwaye isindululo ngonyaka ijikeleza ilanga. Brightness ekukhokeleni ukukhanya kungekho rhoqo kunye notshintsho kunye iintsuku periodicity 4, ngaphakathi 2,02 ± 2%. Eku sunguleni, lo awo le luminance ubemde namhlanje iye yazinza. Aqaqambileyo yeli North Star ikhula rhoqo kwaye liye landa nge phantse i-15% kwiminyaka elikhulu edluleyo.

pulsation yemvelo edibene iimpawu ukukhanya, le yindlela mabaziphathe Cepheids. Ekukhokeleni Star yenye Cepheids ziqaqamba esibhakabhakeni ebusuku.
Dipper Little esibhakabhakeni ithatha indawo izidanga square malunga 255,9. Abamelwane balo basondeleyo unguye Dragon, Cepheus. E asterisk, njengoko sele kuchaziwe, ukuba ligcinwe, eMntla Pole of the World - ingongoma kwisigaba yasezulwini, apho zijikeleza zonke izinto ngeenxa zonke. Sisihlandlo sokuqala Imithombo yembali yenziwa yi-nabakhwitsi Greek uPtolemy kwinkulungwane II.

Ursa Minor neenkwenkwezi yayo

Ubume bale Small Dipper leKima siquka izinto ezisixhenxe olukhazimlisiweyo. Kuzo zonke iinkwenkwezi Dipper amancinane ngokucacileyo ibonakala ezintathu kuphela kakhulu umxhelo. It ferhad and Beta Ursae Minoris oyinxalenye iindonga ukhamba, kwaye ebekwa yi lekroza ajongane North Star. Ngaphezu nomsila Big Dipper ibekwe ezidlulileyo iinkwenkwezi ezimbini.

Indlu Small yahlukile kwezinye namakroza. Akunamsebenzi tshintsha indawo esibhakabhakeni, efana Big Dipper kunye namanye asterisk ukuba ngamaxesha athile onyaka. Baya kunokubonwa ngaxesha lithile besisihla, yaye eshukumayo esibhakabhakeni kulo nyaka. Ursa Minor itshintsha indawo yayo, ejikelezayo ngeenxa Alpha yayo.

"NdinguAlfa no-Omega" ye lekroza Ursa Minor kumntla ikhweyitha

Alpha (North Star) Little Dipper imi kumgama ukusuka Umhlaba 431 ngonyaka ukukhanya. Ngenxa yobukhulu ngokucacileyo ilingana 2,02. Njengoko Kwazeka oko, akukho namnye, kodwa iinkwenkwezi ezintathu amanyene kwinkqubo enye. Ezikhanya phakathi kwabo, phantse izihlandlo 2000 kokuqaqamba kwelanga. Le nkwenkwezi yesibini Ursa Minor enobunzima 1.39 elanga. Oku kunokubonwa kunye iteleskopu encinane. Le nkwenkwezi yesithathu okukhulu ngakumbi Sun wethu Alpha we 1.25, kwaye usondele ngokwaneleyo ukuya kowokuqala. Ngoncedo lwe telescope "Hubble" iye yaba lula ukuqwalasela njengokuba inkwenkwezi enye.

Beta Ursae Minoris - orange omkhulu, Arabic for "The Star of the North". Okwesibini star likhanya ngamandla, le beta, xa lekroza le emele Small kunye ubukhulu ka-2.8 kwaye yasuswa komhlaba 126 ukukhanya-iminyaka.

Ferhad - gamma Ursa Minor, kunye ubukhulu 3.6, umgama kuso 480 ukukhanya iminyaka. Le propati ingqalelo, ingxilimbela eshushu kunye lobushushu 8600 K kwaye ibhekisa kudidi star bume.

Delta Small Dipper, okanye Yildun - nengcungcuthekileyo, nenomlanga emhlophe, nto leyo imi kumgama 183 iminyaka elula.

Zeta - enye, nenomlanga, abamhlophe yaye zibekwe kumgama 380 kwiminyaka ukukhanya Earth. Ubunzulu kukona ayo malunga nezihlandlo 200 ngaphezu koko kwelanga. Uhlala ngendlela kweenkwenkwezi kwi ngxilimbela.

North Star ukuba akayi kukuyekela

Kungenzeka khumbula konke oku akusebenzi, kodwa ulwazi lwakho ebanzi kakhulu. Kwaye ukuba ngebhaqo ulahlekile ehlathini yaye akukho iselula, zama ukukhumbula ukufumana indlela Ursa Minor kwi-Big Dipper. Wena sisingise ukufumana polaris kunye Orient sikekelele kuliphi na icala singasentla.

Isibhakabhaka izele iimfihlakalo kunye eemfihlelo angayaziyo

Nokuba ngaphandle iteleskopu, umzobo nje iliso kwi izikhanyiso ebusuku, uya kubona indlela ezahlukeneyo indalo yethu enkulu. Constellation Ursa Minor - kuphela inxalenye encinane ebonakalayo kuyo. Imida kunye nobukhulu wendalo obonakalayo kuthi namhlanje ngokuqinisekileyo. Le ubungakanani omkhulu ngokwenene, ubude balo - malunga ne-14 billion ukukhanya-iminyaka.

Kodwa ke ukuba yonke enyanisweni? Ingcinga Iyandonwabisa iingqondo oosonzululwazi ezinkulu. Bathi hypothesize, uphando, mpikiswano kwaye uzame ukuqonda ukuba ingaba kunjalo? Ezinye iingcali yabonisa imbono yokuba indalo akupheli, abanye - ukuba kukho imfundiso.

Kwaye kusenokuba kuhle ukuba omnye kubo le planethi, eli lizwe kunye nekopi kuni. Nantoni na ingenzeka, inzululwazi rhoqo utyhala umkhusane engayaziyo kwimboniselo wethu efihliweyo, gqolo engqina ukuba oko kubonakala kwamnandi namhlanje abe ngokoqobo ngomso.
