Phakathi kwezidalwa zasezulwini ezingenakubalwa ezigcwele iNdawo Yonke, kumelwe nakanjani kube neplanethi eyodwa edlula yonke eminye ngobukhulu. Abantu abaningi bafuna ukwazi iyiphi iplanethi enkulu kunazo zonke endaweni yonke eyaziwayo nokuthi yiziphi izici abanazo.
Ngakho-ke, kulesi sihloko sizokutshela ukuthi iyiphi iplanethi enkulu kunazo zonke endaweni yonke nokuthi ziyini izici zayo.
Ungazi kanjani ukuthi iyiphi iplanethi enkulu kunazo zonke endaweni yonke
Ngokwe-Canadian Space Agency (CSA), cishe kunemithala ekhonjiwe eyizigidi eziyinkulungwane eMkhathini. Kuwo ngamunye wale mithala kunezinhlelo eziningi sonozungezilanga, ngamunye uneqoqo lawo lamaplanethi. Ngakho-ke, kunengqondo ukucabanga ukuthi phakathi kwalolu hlu olubanzi lwezinkanyezi namaplanethi, kumelwe kube khona iplanethi engaphezu kwawo wonke amanye ngobukhulu, okungenani ngaphakathi kwendawo yonke ebonakalayo.
Isihloko esifiselekayo seplanethi enkulu kunazo zonke ku-Solar System yethu sasiphethwe yi-Jupiter kwaze kwaba ngu-1992. Kodwa-ke, ukutholakala kwe-exoplanet yokuqala ngalowo nyaka kwavula umncintiswano kuhlu olubanzi lwabazoqhudelana nabo, konke okungase kwehlise kalula ubukhosi bethu umdondoshiya wegesi esiwuthandayo.
Isayithi eliyisipesheli I-Live Science iphakamisa ukuthi uma kucutshungulwa lolu daba, kunezilinganiso ezimbili ezinquma iplanethi enkulu kunazo zonke ku-Universe: ububanzi nobukhulu.
Nakuba kukhona ukuxhumana phakathi kwalokhu kokubili, akukhona ngaso sonke isikhathi ukuhlobana okulula. Ake sithathe njengesibonelo i-exoplanet HAT-P-67 b, ene-radius cishe ephindwe kabili kune-Jupiter. Ngokumangalisayo, le ndikimba yasezulwini inokuminyana okuphansi ngokuphawulekayo, okuholela ekubeni kube nesisindo esiyingxenye eyodwa kwezintathu kuphela yeJupiter. USolène Ulmer-Moll, umcwaningi we-exoplanet e-University of Geneva, unikeze lolu lwazi ku-Live Science.
Njengamanje, amaplanethi amakhulu kunawo wonke akhona ayaziwa ukuthi anesisindo esiphindwe izikhathi ezingu-13 kuneJupiter. Ilungu eliphawulekayo lalesi sigaba yi-HD 39091 b, etholakala cishe iminyaka engu-60 yokukhanya ukusuka eplanethini yethu, enesisindo esidlula leso sendikimba yasezulwini enkulu kunazo zonke kuSolar System yethu ngesilinganiso esingu-12.
Iyiphi iplanethi enkulu kunazo zonke endaweni yonke
Ngokusekelwe kokutholwe ngu-Andrea Fischer, intatheli edabuka eMexico futhi esebenzisana ne-National Geographic en Español, Kunqunywe ukuthi i-ROXs 42Bb, indikimba yasezulwini, ibambe umehluko wokuba into enkulu kakhulu phakathi kolwazi lwethu lwamanje lwe-Universe.. Ngosayizi ophindwe kabili nohhafu lowo we-Jupiter, futhi okungenzeka ube mkhulu nakakhulu, kufanele kuqashelwe ukuthi izilinganiso ezitholiwe zingase zinganembile ngokuphelele.
U-Andrea Fischer uchaza ukuthi enye yezindlela ezisetshenziswayo ukuze kutholwe ububanzi bayo ihlanganisa ukukala inani lokukhanya elikuvimbayo phakathi nokuhamba kwayo ngenkanyezi yayo emaphakathi. Nokho kuyacaca ukuthi uma buqamama kungase kube khona imidondoshiya ethe ukudlula isicoco esikhona njengamanje.
I-ROXs 42Bb, i-exoplanet etholwe kuze kube manje, Idlula i-Jupiter okungenani izikhathi ezingu-2,5 ngosayizi, okuyenza ibe i-exoplanet enkulu kunazo zonke eyaziwayo.
I-ROXs 42Bb
I-ROXs 42Bb, iplanethi enkulu kunazo zonke emlandweni we-Universe, idlula ngisho ne-Jupiter, i-gas giant ebusa phakathi kwamaplanethi angomakhelwane bethu. Ngokuphindwe izikhathi ezingu-11 ubukhulu boMhlaba, isikhundla sikaJupiter njenge-colossus ephakeme sihlala singenakuphikiswa. Nokho, ngobukhulu be-cosmos, iplanethi yesihlanu kuSolar System yethu ayilutho uma iqhathaniswa nobuhle be-ROX 42Bb. Ngeshwa, ulwazi lwethu ngalendikimba yasezulwini engavamile lulinganiselwe kule mininingwane embalwa.
Emkhathini omkhulu weNdawo Yonke, kunezinto ezinobukhulu obumangalisayo nezihlukahlukene kangangokuthi zifiphaza ngisho namaplanethi amakhulu kunawo wonke kuSolar System yethu. Isibonelo yi-UY Scuti, inkanyezi enkulukazi enesihloko sokuba enkulu kunazo zonke ezikhona. Uma kuqhathaniswa, iLanga lethu lizobonakala lilincane, lifana nesinambuzane esilula lapho sikhona.
Akukhona okungalindelekile, uma kubhekwa lezi zimo, ukuthi indikimba yasezulwini eyaziwa ngokuthi i-ROXs 42Bb idlula i-Jupiter, iplanethi enkulukazi enegesi eSolar System yethu, ngobukhulu obuphindwe kabili nengxenye. Kungenzeka nokuthi lesi silinganiso senzakala, njengoba izilinganiso zaleli bhizinisi elikhulu zingase zingathembeki ngandlela thile. Enye indlela esetshenziswayo ukuze kutholwe ububanzi bayo, ngokwesibonelo, ihilela ukubheka ukukhanya okuvimbile phakathi nohambo lwayo ngenkanyezi engumzali wayo.
I-Jupiter efana ne-ROX 42Bb ingeyesigaba semidondoshiya yegesi. Nokho, ubukhulu bayo buphindwe izikhathi ezingaphezu kweziyisishiyagalolunye kokweplanethi yesihlanu kuSolar System yethu. Ososayensi be-NASA basebenzise ukuhlukahluka kwejubane leplanethi ukubala ubukhulu bayo, okubavumela ukuba banqume izici ezengeziwe zalesi sigungu sasezulwini.
Ezinye izici ze-ROXs 42Bb
Lezi ezinye zezici zeplanethi enkulu kunazo zonke endaweni yonke erekhodiwe njengamanje:
- I-orbit yayo ihlanganisa ibanga elimangalisayo lamayunithi angu-157 ezinkanyezi.
- Isikhathi se-orbital se-ROXs 42Bb nxazonke Inkanyezi yayo cishe ineminyaka engu-1968,3 ubudala, iqeda umjikelezo ogcwele ngaleso sikhathi.
- Inkanyezi eyinhloko yale ndikimba yasezulwini ingeyohlobo luka-M, okubonisa ukuthi ikhipha ukukhanya okufiphele ngokuphawulekayo.
Yatholwa ngo-2013 futhi yaqanjwa ngokuthi i-ROXs 42Bb. Njengoba iqhele ngebanga elingama-488 light years, isibekela uMhlaba ngesilinganiso esingu-22. Itholakala kuphela ngemishini yesimanjemanje ye-telescopic, le nhlangano enkulu yatholwa eduze kakhulu nomlaza we-Ophiuchus. Kuze kube manje, ayikho enye i-exoplanet esiye yavela engaqhudelana nenani layo elikhulu, iqinise isimo sayo njengompetha obusa usayizi ngaphakathi kwendawo yonke ebonakalayo.
Njengoba ubona, umkhathi wethu uhlale usinikeza ulwazi olusha olusenza kudingeke sibuyekeze yonke idatha esinayo. Into efanayo, okwamanje sikholelwa ukuthi i-ROXs 42Bb iyiplanethi enkulu kunazo zonke endaweni yonke futhi, nokho, phakathi neminyaka embalwa kuzotholakala ukuthi kunenye iplanethi enkulu nakakhulu.. Konke lokhu kufezwa ngokuthuthuka kobuchwepheshe.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi iyiphi iplanethi enkulu kunazo zonke endaweni yonke kanye nezici zayo.
