M'mlengalenga Pluto n'chiyani? Pluto mlengalenga: zikuchokera

Pluto mlengalenga - thumba kwambiri chachinsinsi mpweya wa System Dzuwa. Choyamba, chifukwa zimakhala ngati kuti asakhalenso pamwamba, ankasiyana zingalowe m'malo a. Ena mwa particles ake kufika Charon. Chachiwiri, osalimba pa avareji kangapo kuposa osalimba a m'mlengalenga. Komabe, mipweya umene uli, mwatsoka, si abwino kwa anthu. Bwino ndi chachitatu, zinkakhalira Pluto - chodabwitsa variable. Popeza kachulukidwe ake ndi kulemera akhoza asamasanduke nthunzi otchedwa "chilimwe" pa dziko. Ngati izi ndi zambiri zochitika zina zimene zimachitika pa Pluto, ndinu chidwi, timapereka kwa agwera mu dziko lake.

Kodi kufufuza dziko chinayi?

Pluto - chinayi chinthu ku Sun, amene ali nawo mu gulu la mapulaneti nyenyezi yaing'ono ya SS. Kwenikweni m'zaka watha, iye anali malo a ulemu pa dziko kumalekezero a nyenyezi wathu. Patapita anapeza kuti chinthu ndi mbali ya Kuiper lamba, ndi magawo ake ngakhale zochepa wosayankhula ena mapulaneti nyenyezi yaing'ono imene ili lamba asteroid. Pluto ndi kanjira - waukulu mu dongosolo lathu, chifukwa kukhota wathunthu mozungulira dzuwa pano kumatenga 248 Earth zaka. M'nyengo yathu, -lenga mwayi kusunga chilimwe Plutonian. Zimenezi ndi zabwino chifukwa dziko pafupi ndi dzuwa, izo Tingaone bwino lomwe kudzera zakutali ndi. Nthawi imeneyi, mpweya Pluto ndi kwamphamvu uko. Poyamba, linakhalapo chimene chasonyeza ndi Wonenedwa, koma kenako ankaona mpweya chivundikirocho anali zikomo zotheka Optics lapansi.

Kutsegula mlengalenga

Dziko Pluto anapeza posachedwapa - mu 1930. Iye ananena chinayi zonse kunachitika CC chinthu ndi ngati inu kuyiwala za izo kwa kanthawi. Mu zaka 80 ananena dziko adapitiriza. Kwambiri zithunzi zimapezeka chifukwa cha Hubble Space Telescope, amene adatitsegulira zinsinsi za chilengedwe cha. Mu 1985 iye anali woyamba anatulukira mpweya Pluto a. The zikuchokera thumba mpweya analephera kukhazikitsa njira masamu, monga sikunali kotheka kukhazikitsa yoyenda potenga zitsanzo mpweya. Likufanana ndi ichi, wakhala anaphunzira ndipo pamwamba lathuli. Kunapezeka kuti tichipeza crystalline ayezi youma ongokhala hydrogen ndi madzi. Ngakhale kuti dzikoli ndi olimba, ngati Lapansi, ndi pamwamba ukuphwera, ndipamene wosanjikiza mpweya. Chifukwa zikuchokera zigawo ziwiri izi ndi zofanana kwa wokongola kwambiri amachita zakuthambo ntchito mosavuta.

Chemical chigawo chimodzi

Akuyendera kuphunzira katundu ndiponso zimene ankachita mpweya zosiyanasiyana malo, kuyang'ana pa zomwe zili m'mlengalenga Pluto a. Izi chipolopolo mwachilungamo wandiweyani, m'lifupi umene uli wofanana makilomita 3000. Bukuli lili asafe - izo ali 99% ya malo onse mpweya. peresenti 0,9 ndi carbon monoxide ndi yotsala kukhala dziko. mipweya zonsezi kuuluka padziko lonse chifukwa iwo asanduke nthunzi ayezi kuphimba nkhope yake. M'kupita kwa nthawi, ndondomeko ya ukuwonjezeka evaporation mu lonse, potero kuwonjezeka Pluto mlengalenga. kapangidwe kake Komabe, akanali yemweyo, koma sublimation amatenga sikelo kwambiri padziko lonse. Iyi imalimbikitsa kuwonjezeka kutentha kwa zakuthambo, komanso kuwongola wa kumunda yokoka. Mwina mtsogolo, zomwe sizingafanane ndi moyo wa munthu, Pluto adzakhala lokhalamo dziko.

Pluto m'chilimwe thumba mpweya

Ife tanena kale kuti tsopano akuyang'ana kupyolera makinawa pa Pluto mukhoza kuona mmene zimakhalira chilimwe. Nthawi imeneyi, dziko pafupi Dzuwa ndi kutentha lalikulu. Inali pa nthawi imeneyi anapanga mlengalenga gaseous wa Pluto, lomwe ndi dziko lapansi, ndipo ofufuza anali kuona kupyolera zakutali ndi. M'chaka chifukwa zotsatira kutentha, lomwe limapezeka mchikakamizo cha dzuwa, evaporation amapezeka. Only ndiye pamwamba si lidzasinthidwa madzi oundana, ndi kamodzi mu mpweya, kuyambira yokoka pa Pluto olumikizidwa ku makina. gasi tichipeza kwakukulukulu wa asafe, kunama chimphona rekodi-mtambo wa dzikoli, ngakhale pang'ono kubwera pa izo ndi kupanga otchedwa zingalowe wosanjikiza. Ena mamolekyulu wa asafe ndi methane ndi kukwaniritsa padziko Charon. Kudzera chaka chino zotsatira kutentha, mu Ndipotu, zatsimikizira kuli mpweya Pluto a. Asayansi aona kuti dziko alibe ndondomeko, ndipo monga ngati mu kuya kwa mtambo waukulu. Pa anayendera pafupi ife anakhazikitsa lonse la mfundo.

Zima mu ufumu ozizira

Ngati anthu wafika lero pamwamba njira zamakono zaka 200 zapitazo, kutsimikizira kuli mpweya Pluto zidzakhala zosatheka,. Mu nthawi imene dziko nyenyezi yaing'ono ukusunthira kutali Sun, mipweya zonse, zimene ndifungatire pa izo m'chilimwe, anabwerera pamwamba ndi mbali ya glacier limene iwo mbisoweka kumayambiriro kwa nyengo lomaliza. Pankhaniyi, Pluto zikuwoneka kwathunthu "maliseche", ndipo maphunziro ake kuoneka bwino bwino mu zakutali, monga si chosokonezedwa ndi mpweya cladding.

Kutentha mu zigawo zosiyanasiyana za m'mlengalenga

Ife ndaphunzira kuti mpweya akamazizira chipolopolo dziko lapansi monga mtunda kuchokera pamwamba, ndi ambiri amakhulupirira kuti mapulaneti onse, zinthu chimodzimodzi. Koma izi si choncho, ndi chitsanzo chabwino cha zimenezi ndi chikhalidwe cha Pluto. Padziko lapansili ndi amazipanga ozizira - madigiri 231 pansi pa ziro. Ndi khalidwe chithunzi ndi wosanjikiza m'munsi ya mpweya. Monga mtunda kuchokera ayezi pepala okhazikika okhudza Pluto, kutentha limatuluka. Mu chapamwamba zigawo za m'mlengalenga , ife kale anakumana chizindikiro madigiri -173, amene mfundo zachilendo kwa chilengedwe danga. Komanso, apa pali chododometsa chidwi. Mu chilimwe, pamene mpweya ndi wosiyana dziko, chifukwa sublimation padziko akamazizira pansi kwambiri. Izi otchedwa odana ndi Kufunda. M'nyengo yozizira, chifukwa chakuti mpweya zikawoneka, ndi Pluto dzuŵa mwachindunji, kuwundana wamuyaya kutenthetsa pang'ono.

kumwamba Pluto

Chifukwa chakuti munda yokoka ya dziko nyenyezi yaing'ono ndi chochepa, kuti sasunga mlengalenga momuzungulira. mipweya imeneyo kuti asanduke nthunzi, ndi kuchotsedwa pamwamba, palibe njira kuteteza dziko chifukwa cheza dziko ndi asteroids. Koma ngakhale nthunzi ya osakaniza asafe ndi carbon monoxide akhoza yochulukirapo pa kutumphuka wa Pluto, moyo wotere, munthu ndithudi sindikanatha. Chifukwa sitili a hayidirojeni, ndi chifukwa cha malo otsika kwambiri osalimba, Pluto maximally zatha mlengalenga. Zimenezi zikutanthauza kuti pali simungakhoze kupanga wosanjikiza wapadera umene kusintha mtundu wa thambo, malingana ndi nthawi ya tsiku. Choncho, theoretically, pamene Pluto, iwe sungakhoze kuwauza usana ndi usiku. Ataima pamaso panu adzatembenuza wakuda dera limene cheza yowala adzauka nyenyezi ndi zouluka zapitazi dziko.

Pomaliza

Tsopano zakuthambo ndi chidwi kwambiri ndi mtundu wanji wa mlengalenga Pluto kwenikweni. Kodi anapezazo ndi kuyang'anila zinthu molondola ndiponso ngati akugwirizana ndi chenicheni? Pali mapulani kukhazikitsa kachipangizo kuti adzakhala wakutheker kugonjetsa zili m'njira ya zimphona mafuta, kenako anafika pa Pluto. Akuti chombo kuti anapezerapo m'mlengalenga dziko nyenyezi yaing'ono, lidzafika pamwamba ndipo adzatha zitsanzo za m'mlengalenga ndi ayezi. Ndipotu palibe luso zosokoneza kwa zinthu mankhwala, monga Jupiter, palibe.
