7 kakhulu kunazo zonke ezake ukutholwa ososayensi amaplanethi

muva Izazi zesayensi ziye zakhomba iplanethi ezishisa nge lokushisa kwamanzi obukhulu kunobukaJohane ezinye izinkanyezi. Njengoba ukuzingelwa amaplanethi ngaphandle komthala njalo kwenzekani, eziningi nezinye imihlaba ezinezici kakhulu etholakele. Njengoba ucwaningo emkhakheni isikhala nazo zaba neqhaza ekutholakaleni ezinye amaplanethi kunalokho eziyinqaba. Isihloko kuveza eziyisikhombisa ezinzima kakhulu.

ezishisa

Indlela ashisayo iplanethi kuncike, ngokuyinhloko, eduze kangakanani inkanyezi yayo aphethe, futhi ngendlela lapho inkanyezi burns ashisayo. Ohlelweni lwethu, Mercury - iplanethi esiseduzane ilanga. Itholakala at ibanga 57.910.000 km. Amazinga e-emini ezingeni ifinyelela mayelana 430 ° C, kanti Kwamanzi sishisiswe 5500 ° C.

Star HD 195689, eyaziwa ngokuthi KELT-9b, izikhathi 2.5 njengemishini emikhulu edlulisela njengoba ilanga. Indawo yayo ukufuthelana cishe 10 000 ° C. Le planethi useduze nakakhulu aphethe inkanyezi kuka Mercury iwukuba ilanga.

coldly

Lapho Inkomba lokushisa 223 ° C Ogle-2005-BLG-390Lb atholwe isimo iplanethi enomoya. Mhlawumbe njengoba umhlaba, izophinda embozwe okwakheke ngayo amadwala. Nakuba akusiyo ikude inkanyezi yayo aphethe emzileni, okuyinto wasibeka esimisweni sonozungezilanga endaweni ethile phakathi Mars kanye Jupiter, umnikazi walo - inkanyezi eyaziwa ngokuthi oyisichwe abomvu.

Leplanethi ezibandayo kabanzi okukhulunywa ngayo movie "Star Wars." Nokho, ngokungafani sibonelo sakhe yokuzicabangela, ayikwazi ukumelana ingxenye enkulu ebangelwa umkhathi, kanye angafaneli ukuphila. Lokhu zingachazwa ngezinqubo yokuthi ingxenye igesi uzobe simisiwe, kanye ebusweni limbozwa iqhwa okuqhubekayo.

ngobukhulu

Uma iplanethi kungaba njengamalangabi inkanyezi ke yini umehluko phakathi kwalokhu? Izinkanyezi namaplanethi ngoyisiwula kusinda kakhulu. Bona okhela ngesikhathi inqubo ekubumbaneni ngenxa omkhulu amandla adonsela phansi-nucleus. inkanyezi Ezivamile, isibonelo ilanga yethu ibingavuthi yini hydrogen-helium. Kodwa kukhona uhlobo izinkanyezi, ngokuthi dwarfs ensundu. Lezi izinkanyezi zinkulu ngokwanele ukuqala abanye sihlangane, kodwa akanawo usayizi anele ukusekela kwabo.

Planet DENIS-P J082303.1-491201 b izikhathi 28,5 ngoyisiwula kusinda kunakho Jupiter. Kuyinto ukuba mikhulu. ososayensi Poetmu zidingide ngokuthi kwakungase kubhekwe isigaba amaplanethi noma usalokhu inkanyezi brown yemifino. Kuyathakazelisa ukuthi inkanyezi yayo aphethe kuqinisekisiwe yemifino ensundu.

aphansi

Kepler-37b lithé ukuba likhudlwana kune inyanga yethu, nobumbalwa Mercury. Lokhu luncane iplanethi extrasolar. Rock kumiswa eduze inkanyezi yayo aphethe kuka Mercury iwukuba ilanga. Lokhu kusho ukuthi lo mhlaba uyikhaya ashisayo kakhulu ukusekela namanzi, futhi ngaleyo ndlela ukuphila ubuso bayo akunakwenzeka.

Ezindala

PSR B1620-26 b has iminyaka engaba yizigidi eziyizinkulungwane 12.7. Kuyinto iplanethi esidala kunazo zonke ezaziwayo. Kuyinto izikhathi 2.5 ngoyisiwula kusinda kunakho Jupiter.

PSR B1620-26 b has a amabili aphethe-inkanyezi, uzungeza nomunye. Iplanethi kungokwalabo esigabeni ka-neutron izinkanyezi dwarfs ezimhlophe. Njengoba kwamiswa emlandweni ekuseni wendawo yonke, kungenzeka akanayo inombolo ezanele Izakhi ezisindayo ezifana yekhabhoni nomoya-mpilo, okuyinto akhiwa kamuva. Lezo zinto ezidingekile ukuziphendukela kwemvelo kokuphila.

Omncane

uhlelo yemihlaba V830 Tauri iminyaka 2 million. aphethe Star inobungako obufanako njengoba Sun yethu kodwa izikhathi ezimbili enkulu kunemicebo engaba, okusho ukuthi ingakamiswa some ngokugcwele.

Le planethi giant igesi ne izingxenye ezintathu kwezine nenqwaba Jupiter. Ungishiya cishe namanje inqubo yokukhula. Lokhu kusho ukuthi-ke ozuza eyinqwaba, babhekana lezo zidumbu kwamaplanethi, efana asteroyidi, futhi kwenza kube indawo engaphephile.

sezulu esibi kunazo zonke

Uma uthinta isihloko ezifana sezulu kuyisiqalo esibi kunazo zonke, khona-ke siyaqiniseka ukuya mayelana Venus. Planet ubukhulu efanayo Earth. It is igcwele ngu namafu sulfuric acid.

ezinyakazayo Atmosphere on Venus kuyinto ngokushesha okuningi kunalokho ukujikeleza iplanethi uqobo, futhi ifinyelela isiphepho somoya ijubane 360 km / h.

izishingishane kabili ephethwe agcinwa ku isigxobo ngamunye. Isibhakabhaka ku Venus kuyizikhathi 100 nesisindo esikhudlwana kuka Earth, futhi yakhiwa-carbon dioxide. Ngenxa yalokho kwamagesi abamba ukushisa emkhathini kudala lokushisa Infernal okungenani 462 ° C ngaphezulu ukuthi empeleni kwenza kube ibavuthela Mercury. Naphezu ezomile futhi ephikisana ukuphila, lokhu ukushisa kungenzeka kuyisizathu esenza phezu Venus izintaba-mlilo ezincane kuno ku surface eMhlabeni.
