Trans-Neptunian zinthu: lingaliro, mitundu

Kunja kwa mzinda wa dongosolo lathu dzuwa ndi Kuiper lamba. Iye amapita kunja kanjira Neptune, choncho yapita ndiziwona chirichonse mu mlengalenga zakhala zovuta kwambiri. Komabe, bola ngati anthu alipo anaonekera telesikopu amphamvu, izo anatha kupanga ena kutulukira. Mwachitsanzo, anadziwika kuti zinthu Trans-Neptunian - unit yaikulu ya amapanga Kuiper lamba, ndi Oort mtambo ndi kuwabalalitsa chimbale. M'pofunikanso tione thupi, onsewo mu "kumbuyo" a dongosolo la zowalitsa.

Trans-Neptunian akutsutsa - thupi dziko likuzungulira dziko mu kanjira kake. Yotchuka kwambiri zinthu izi - Pluto, ankaona dziko mpaka 2006. Komabe, kwa tsiku, Pluto - achiwiri kukula Trans-Neptunian zinthu. Avereji mtunda kwa zounikira mu matupi awa ali woposa pa Maplaneti ozungulira dzuŵa lathu - Neptune.

Panopa kutsegula zoposa zikwi zinthu zimenezi. Komabe, asayansi timakonda akukhulupirira kuti mfundo pali zambiri.

Yaikulu Trans-Neptunian zinthu - Eris. Zinali lotseguka mu 2005. The kutali kwambiri kuchokera ku Kuwala m'thupi lathu, amene alibe dzina, ndi pa ndandandapo pa nambala V774104. Iwo amachotsedwa Sun pa 103 mayunitsi zakuthambo.

TNO onse m'magulu anayi.

kulekanitsidwa TNO

Ozungulira dzuŵa lathu pali subclass a mtundu umenewu matupi: alibe chinthu. Iye anaitanitsa chifukwa, mwa mawu a perihelion matupi amenewa ili pa mtunda wautali kuchokera Neptune, choncho si bwanji yokoka ake. Zimenezi zimapangitsa mayiko awa pafupifupi ufulu osati kokha kwa Neptune, komanso dongosolo lonse dzuwa lonse.

Mwaukadaulo, awa zinthu matupi anawonjezera anamwazikana litayamba. Panopa deta zilipo kwa zisanu ndi zinayi za matupi, koma mndandanda zikuoneka posachedwapa adzakhala kwambiri kuchuluka.

Mmodzi wa mamembala a gulu TNO - Varuna. Atsegula November 2000.

Chakale Kuiper m'Galimoto chinthu

Dzina la gulu la matupi anabwera kuchokera kuwerenga oyamba - QB1. N'chifukwa chake Trans-Neptunian zinthu, limene lili mu Kuiper lamba, wotchedwa cubewanos (cue-zina kuti adzipeza Ouen). Kanjira zinthu izi tsidya kanjira wa Neptune, pamene iwo anasonyeza ndi kumveka yozungulira ndi dziko.

The zili m'njira ambiri cubewanos ndi mawonekedwe pafupifupi zozungulira pafupi ndege ecliptic. Mbali yaikulu ya matupi awa amakonda pa ngodya ochepa, inayo lalikulu kuweramira kumathandiza kupeza ngodya zabwino ndi m'mipita kwambiri elongated.

Mbali yaikulu ya matupi cha gulu ili ndi mfundo zotsatirazi:

• zawozo konse intersect kanjira wa Neptune.
• Zinthu sizili resonant.
• eccentricity awo - zosakwana 0.2.
• muyezo awo Tisserand kuposa 3.

Classic woimira gulu - Quaoar, mmodzi wa matupi waukulu kwambiri Kuiper lamba. Iwo anatsegula mu 2002.

resonant TNO

Resonant Trans-Neptunian zinthu ndi amene kanjira ali yozungulira kumveka ndi Neptune.

Tikamaphunzira mosamala zinthu izi zimathandiza kuti kulankhula za narrowness malire a zinthu resonant. Nthawizonse kukhalabe malire amenewa, thupi pamafunika wina kuchuluka kwa mphamvu, palibe ndi chimodzimodzi. Kuonetsetsa kuti anatuluka kanjira kumveka, ndi lophweka: chabe kakang'ono kupatuka wa olamulira theka-yaikulu ya malire anakhazikitsa.

Pamene kutsegula kwa nyumba zatsopano anapezeka kuti kuposa chakhumi a iwo ali mu kumveka 2: 3 ndi Neptune. Akukhulupirira kuti ubwenzi woterewu si mwangozi. Ambiri mwina, zinthu izi anasonkhana ndi Neptune pa kusamuka kwa m'mipita akutali.

Pamaso woyamba zinthu Trans-Neptunian, akatswiri ankaganiza kuti zochita za mapulaneti aakulu pa galimoto yaikulu kuchepetsa ndi theka-mzere ndi kuwonjezapo theka-nkhwangwa Jupiter Uranus, Neptune, ndi Saturn linatsegulidwa.

Mmodzi wa akuluakulu a gulu ndi Orc - Trans-Neptunian zinthu, yomwe ili Kuiper lamba.

Anamwazikana zinthu chimbale

Ichi ndi thupi mu dera akutali kwambiri a dongosolo lathu dzuwa. osalimba a zinthu m'dera limeneli ndi otsika. zomwazikazo matupi onse chimbale ndi lopangidwa ndi ayezi.

Magwero a m'dera limeneli sanali bwino. Asayansi ambiri timakonda amakhulupirira kuti chinapangidwa pa nthawi imene zotsatira yokoka ya mapulaneti kuoneka zotsatira osakwanira pa Kuiper lamba, kotero kuti malowo anabalalikira m'madera wokulirapo kusiyana ndi lero. Omwazikana litayamba, poyerekeza ndi Kuiper m'Galimoto - malo osakhazikika. Thupi m'menemo woyendayenda osati "yopingasa" malangizo, komanso mu "ofukula", ndi pafupifupi mtunda wofanana. mawerengeredwe Computer zasonyeza kuti ena mwa zinthu akhoza kukhala meandering kanjira, gawo - osakhazikika. Izi zimathandiza kuganiza kuti thupi adzamasulidwa ku Oort mtambo kapena zambiri.

anapeza latsopano

Mu July 2016 chinapezeka wina zambiri Trans-Neptunian zinthu. miyeso ake ali ochepa kwambiri (m'mimba mwake - 200 km), ndi 160 zikwi nthawi fainter kuposa Neptune. Dzinali latembenuzidwa kuchokera ku njira Chinese "kuukira." Kodi dzina la chinthu analandira kuti imazungulira zosiyana ndi kayendedwe ka chitetezo cha dzuwa, monga izi zingathe kufotokozedwa kokha chifukwa chakuti aliyense thupi mokwanira amphamvu kusonkhezera izo, kusintha kanjira kake.

khalidwe la nyumba zatsopano amakakamizidwa asayansi kusochera, chifukwa pa nthawiyo si bwino zimene dziko ndi mmene akanakhoza kupanga "wopanduka" akusuntha mu zoterezi kanjira. Akatswiri a sayansi ya kulingalira kachiwiri za kuli ngati dziko wosadziwika, zomwe zimatha kukopa cholimba pa matupi ena.
