Umdlavuza ungomunye wemilaza eyishumi nambili ye-zodiac, etholakala enyakatho nenkabazwe, ikleliswe endaweni yama-31 phakathi kwemilaza enendawo enkulu yasezulwini, ehlanganisa indawo engama-506 square degrees. Ingabonakala ezindaweni eziphakathi kuka-+90° no -60°. Kwe Umdlavuza womlaza Iyaziwa kodwa abantu abaningi abazi ukuthi ingayithola kanjani esibhakabhakeni.
Kulesi sihloko sizokutshela zonke izici, umsuka kanye nencazelo yomlaza weCancer.
Izici eziyinhloko
I-Cancer inento eyingqayizivele yokuthi yizimpawu ezinzima kakhulu ze-zodiac. Ayinazo izinkanyezi ezinobukhulu obungaphansi kuka-3. Ayinkulu kakhulu, kepha ikleliswe endaweni yama-31 ukusuka kwenkulu kuye kwencane phakathi kwamaqoqo ezinkanyezi esimanje angama-88. Ihlanganisa indawo ephelele yama-degrees square angama-506.
Umlaza utholakala kuquadrant yesibili ye-northern hemisphere futhi ubonakala kunoma iyiphi i-latitude engaphezu kwama-degree angu-60 eningizimu. Imilaza engomakhelwane bayo iLynx, Gemini, Canis Minor, Hydra, Leo, neLeo Minor. Ku-zodiac, iphakathi kukaLeo noGemini. Lo mlaza uqukethe imithala ehlukene kanye nezinto zikaMesiya ezithakaselwa kakhulu izazi zezinkanyezi.
Umsuka kanye nezinganekwane of the Umlaza Cancer
Ezinganekwaneni zamaGreki, izinkalankala zihlotshaniswa nemisebenzi eyishumi nambili yeqhawe uHercules. Ngokusho kwezinganekwane, inkalankala yathunyelwa isitha sikaHercules, unkulunkulukazi uHera, ukuze imphazamise lapho ebhekene ne-monster Hydra. U-Hercules wakwazi ukunqoba i-Hydra ne-Crab futhi ubeke izidalwa ezimbili esibhakabhakeni njengezinkanyezi.
Ezikhathini zasendulo, i-solstice yasehlobo yenzeka kuCancer yomlaza. Njengamanje, i-solstice yasehlobo ithuthele e-Taurus ngenxa yokudlula kwe-vernal equinoxes.
Izinkanyezi zomdlavuza womlaza
Umdlavuza uwuphawu olufiphele. Awunazo izinkanyezi ezingaphansi kobukhulu obungu-3, futhi izinkanyezi ezimbili kuphela ngaphansi kobukhulu obungu-4. Nakuba ungakhanyi kangako, umlaza unezinkanyezi ezingu-104 ngaphansi kobukhulu obungu-6,5, ngakho ungabonakala ngeso lenyama uma izimo zezulu zipholile.
Izinkanyezi ezilandelayo zingezinye ezibaluleke kakhulu kumlaza.
- I-Alpha Cancri: iwuhlelo lwenkanyezi oluhlanganisa okungenani izinkanyezi ezimbili (mhlawumbe ezintathu). Ingxenye eyinhloko inkanyezi emhlophe emfishane enobukhulu obungu-4,26. Lokhu kwenza inkanyezi ibe inkanyezi yesine egqama kakhulu emlazeni. Inkanyezi yaziwa nangokuthi ama-Acubens, okusho ukuthi uzipho lwenkalankala ngesi-Arabhu. Elinye igama elisetshenziswe ukuchaza le nkanyezi nguSertan.
- I-Beta Cancri: Yaziwa nangokuthi i-Altarf, okusho indawo ecijile ngesi-Arabhu. Lena inkanyezi ekhanya kakhulu kumlaza weCancer enobukhulu obungu-3,5. Inkanyezi iyisidondoshiya esiwolintshi esitholakala eminyakeni engama-290 yokukhanya ukusuka esistimu yethu sonozungezilanga. Okunye okugqamayo ngale nkanyezi ukuthi ineplanethi enkulukazi eyizungezile. Iplanethi ilinganiselwa ukuthi inkulu ngokuphindwe kasishiyagalombili kuneJupiter.
- I-Delta Cancri: iyinkanyezi yokubona kanambambili eyakhiwe yiDelta Cancri A kanye neDelta Cancri B. I-Delta Cancri A enye inkanyezi ekabili, eyaziwa nangokuthi i-Asellus Australis, okusho ukuthi imbongolo yaseningizimu ngesiLatini. Itholakala eminyakeni engu-180 yokukhanya ukusuka ku-Solar System futhi inobukhulu obubonakalayo obungu-3,94. Isondelene kakhulu ne-ecliptic futhi kwesinye isikhathi isithwe yiNyanga.
- I-Gamma Cancri: Futhi iyisistimu yezinkanyezi engu-158 yeminyaka yokukhanya kusukela ku-Solar System enobukhulu obubonakalayo be-4,66. Igama layo lendabuko i-Asellus Borealis, okusho ukuthi imbongolo yasenyakatho. Ilele eduze ne-ecliptic kanye ne-Alpha Cancer kanye ne-Delta Cancer futhi ngezinye izikhathi ifihliwe yiNyanga ngisho namaplanethi athile.
- Iota Cancri: iyinkanyezi kanambambili etholakala eminyakeni engama-300 yokukhanya ukusuka kusistimu yethu sonozungezilanga. Ingxenye eyinhloko inkanyezi enkulu ephuzi, futhi ingxenye yesibili i-dwarf emhlophe. Lezi zinkanyezi ezimbili zinobukhulu obubonakalayo buka-4,03 no-6,58, ngokulandelana. Lokhu kwenza ingxenye yayo yokuqala ibe inkanyezi yesithathu egqama kakhulu kumlaza.
- I-Zeta Cancri: eyaziwa nangokuthi i-Tegmine, empeleni iwuhlelo lwezinkanyezi eziningi olunezinkanyezi okungenani ezinhlanu. Lolu hlelo luneminyaka engaba ngu-83,4 ukukhanya ukusuka kuSolar System. Ingxenye yokuqala, ebizwa ngokuthi i-Zeta 1 Cancri, inkanyezi kanambambili eyenziwe nguZeta Cancri A kanye ne-Zeta Cancri B. I-Zeta Cancri A iyinkanyezi ekhanyayo eqenjini, enobukhulu obubonakalayo be-5,63. Ingxenye yesibili inkanyezi kathathu ebizwa ngokuthi i-Zeta 2 Cancri. Lolu hlelo lwenkanyezi luqukethe i-Zeta Cancri Ca kanye nenkanyezi kanambambili i-Zeta Cancri Cb.
ezinye izinkanyezi
Ezinye izinkanyezi kuCancer zonke zinkulu kunobukhulu besihlanu. Phakathi kwazo, Kuyafaneleka ukubalula izinkanyezi ezimbili ezinezinhlelo zamaplanethi ezakhiwe ngamaplanethi ayi-5.
Ngokombono wesayensi, inkanyezi ethakazelisa kakhulu i-55 Cancri. Lena kanambambili inkanyezi 41 ukukhanya iminyaka kusukela esimisweni sethu sonozungezilanga, futhi isimiso sayo samaplanethi iqukethe okungenani amaplanethi 5. Kula maplanethi amahlanu, amane ayimidondoshiya yegesi kanti eyodwa iyiplanethi yekhabhoni. Amaplanethi amahlanu abizwa ngokuthi uJansen, uGalileo, uBrahe, uHarriot, noLibercy.
Kukhona nohlelo lwamaplanethi amaplanethi amahlanu azungeze inkanyezi i-HIP 41378. Kulokhu, amaplanethi alinganiselwa ukuthi aphakathi kwesisindo soMhlaba kanye nesisindo seJupiter kabili.
Ilukuluku lomlaza weCancer
- Ingabonakala kuzo zombili izifunda ezisenyakatho naseningizimu.
- I-ecliptic inqamula inkaba yomlaza phakathi kokuphela kukaJulayi nokuqala kuka-August.
- Umdlavuza utholakala ku-30º enyakatho ye-Milky Way futhi, kanjalo, ibonakala ngamaqoqo ezinkanyezi ezimbili ezinhle nezinkanyezi eziningi ezikabili.
- Enyakatho nenkabazwe ingabonakala kusukela ngasekupheleni kwekwindla kuya entwasahlobo, kuyilapho eningizimu nenkabazwe ingabonakala ehlobo nasekwindla futhi ibonakala phakathi nobusuku.
- Alinazo izinkanyezi ezinobukhulu bokuqala, izinkanyezi zifiphele kakhulu, futhi inkanyezi ekhanya kakhulu yomlaza i-Altarf, ekhanya ngokuphindwe izikhathi ezingu-500 kunelanga.
- Umumo weCancer esibhakabhakeni awufani nenkalankala, kodwa uphenduke u-"Y".
- Ibonakala enyakatho nenkabazwe, ikakhulukazi ekuqaleni kwentwasahlobo, naseningizimu ye-hemisphere ekuqaleni kwekwindla.
- Incazelo yeCancer ngesiLatini ithi inkalankala.
- I-Tropic of Cancer yethiwa ngalo mlaza, umugqa we-latitude ophawula indawo esenyakatho kakhulu lapho ilanga lingabonakala khona ngokuqondile phezulu.
- Isekelwe kumlaza waseBabiloni oneminyaka engu-3000 owaziwa ngokuthi iCrab.
- Ine-Tau Cancrids meteor shower
- Kunezinkanyezi ezingu-104 kulo mlaza, ezingu-50 kuzo zibonakala ngeso lenyama.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nenkanyezi yeCancer kanye nezici zayo.
