Ndi dziko kutali kwambiri mu dongosolo la zowalitsa chiyani?

Kuwonjezera pa Dziko Lapansi, muli dongosolo la zowalitsa, buluu kudziko lina - Neptune. Mu 1846 anatulukira kuyamika aziwerenga masamu osati kungophunzira.

ndi dziko kutali kwambiri mu dongosolo la zowalitsa ku Sun chiyani?

Mu 1930, Pluto linatsegulidwa. Mpaka 2006, iye ankaona otsiriza chinayi dziko mu dongosolo la zowalitsa. Ngakhale Neptune - yekha chitatu. Komabe, mu 2006, mayiko zakuthambo Union wapatsidwa tanthauzo latsopano 'dziko' akuti umene Pluto sanagwe. Pali ngakhale Mabaibulo kuti sikuli kwa dongosolo dzuwa, ndipo ndi mbali ya Kuiper lamba.

Komanso, udindo, anali akumanidwa kuchokera 1979 mpaka 1999, pa nthawi ino, Pluto anali mkati kanjira wa dziko Neptune.

Choncho poyankha funso ili: "Ndani dziko kumalekezero a dongosolo la zowalitsa" - angamvele ngati yankho ndi mayina awiri.

Neptune mu nthano za Chiroma ndi mulungu wa kunyanja.

anapeza

Mwalamulo akutali kwambiri dziko mu System wathu Dzuwa - Neptune - anapeza mu 1846. Komabe, mu 1612 limafotokonzera ndi Galileo. Koma ndiye iye ankaona iye nyenyezi amodzi chifukwa losadziwika ndi anatulukira ake.

Kukhalako kwa dziko latsopano pakati pa 1821, pamene kusintha deta mu kanjira a Uranus zinasindikizidwa, amene anali osiyana ndi mfundo tebulo.

Koma kanjira September 23, 1846, pambuyo miyezi iwiri akufunira, kudzera masamu Neptune anatulukira.

dzina lake analandira chifukwa cha masamu, analitsegula (W. Leaver), amene poyamba ankafuna dzina dziko pambuyo yekha.

Neptune ndi mosalekeza kumizidwa madzulo a. chiwalitsiro ake nthawi 900 poyerekeza la dziko lathuli. Sun ku kanjira zimangooneka nyenyezi yowala.

Ndi chimphona pa mtunda wa makilomita biliyoni 4,55, kapena za 30. . E ali ndi unyinji wa nthawi 17,15 lalikulu kuposa Lapansi ndi awiri a - nthawi 4 zambiri. osalimba pa avareji nthawi yekha theka zizindikiro za madzi (1.6 g / Cu. cm). Choncho, Neptune amatanthauza gulu la Mapulaneti akuluakulu, amene mulinso Saturn, Jupiter ndi Uranus.

Dziko lakutali mu dongosolo la zowalitsa amatchedwanso ayezi, chifukwa misa helium ndi wa hydrogen mu kapangidwe kake si zoposa 15-20%.

Ngati zimphona zina, Neptune pa liwiro yopambana amanena nguli. Tsiku lake maola 16,11 yekha. Mozungulira dzuwa, akupanga zisinthe wa mpita pafupifupi zozungulira wa zaka 164,8. Mu 2011 anamaliza zisinthe wake woyamba zonse kuyambira yoyambirira.

Padziko Neptune mphepo yamphamvu ponseponse liwiro pafupifupi amene - 400 m / gawo.

N'zochititsa chidwi kutentha dziko ndi - 214 C pamene kukhala m'munsi. Amadziwika kuti kumalekezero dziko dongosolo dzuwa lili kutentha yake gwero mkati, popeza nthawi 2,7 mphamvu chimachokera mu danga kuposa izo zimatenga kwa dzuwa.

Pa dziko nthawi zonse zikuchitika kusintha kwa nyengo. nyengo kumatenga zaka pafupifupi 40.

makina

Dziko lakutali mu dongosolo la zowalitsa ali 14 makina. Kawirikawiri anawagawa m'magulu atatu:

- Internal: Talas, Naiad, Galatea, Despina, Larissa, Proteus;

- payokha kuonetsetsa Nereid ndi Triton;

- zisanu makina yachilendo alibe dzina.

Gulu loyamba zikuphatikizapo clumps mdima kufika 100-200 Km kukhala ndi mawonekedwe osasamba. Iwo atembenuza mu kanjira zozungulira pafupifupi dziko. Amauluka padziko lapansili maola ochepa chabe.

Gulu lachiwiri zikuphatikizapo Triton. Ichi ndi kachipangizo mwachilungamo lalikulu. awiri ake - za 2,700 Km, ndi zolowa okwana padziko Neptune izo zimachita kwa masiku 6. Mizere yozungulira, pang'onopang'ono kuyandikira dziko. Poyamba udzaphwanya Neptune ndi mchikakamizo cha mphamvu osefukira kutembenukira kwa mphete wina. pamwamba pake ndi ozizira, akukhulupirira kuti pansi ayezi kutumphuka othamanga nyanja.

Nereid ukuzungulira chimphona kwa masiku 360. Ilinso ndi mawonekedwe osasamba.

makina kunja ali kutali kwambiri (mamiliyoni ambiri makilomita) kuchokera Neptune. Ambiri ntchentche zakutali padziko lonse kwa zaka 25. Poganizira kanjira zolingalira zawo kwa ndege yamphamvu ndi kayendedwe n'zosiyana, anaganiza kuti iwo anagwidwa ndi Neptune mu Kuiper lamba zinthu.

Kanema otsiriza chinamasulidwa mu July 2013.

Neptune ali mphete asanu ndi tinthu ayezi. Ena a iwo wapangidwa mpweya, kotero kuti iwo zimatulutsa wofiira. Amaonedwa kukhala wamng'ono ndi sakhalitsa. Mphete za Neptune wosakhazikika ndi wosiyana kwambiri ndi mzake.

mfundo zosangalatsa

Tsatirani funso pa za mmene mapulaneti kutali ndi dzuwa dongosolo kudziwika spacecraft "Voyazhder 2" unayambitsidwa, tinganene kuti poyamba anali azikaphunzira Jupiter ndi Saturn, koma njira lakwaniritsa monga Uranus ndi Neptune. Iwo unayambitsidwa mu 1977.

August 24, 1989, iye anawulukira mu 48 chikwi. Km wa Neptune. Panthawi imeneyi, Dziko Lapansi anatumizidwa zithunzi za dziko ndi Kanema wake Triton.

Mu 2016 izo, pakutoma, kutumiza kwa wina spacecraft dziko. Komabe, pa nthawi yeniyeni Launch tsiku si.
