Tinoziva kuti solar system haipere zvakananga kana tapfuura orbit yeplanet Pluto. Iyi solar system inoenderera mberi zvishoma ne kuiper belt. Kuti tisvike ikoko, tinofanira kuenda kunzvimbo dziri kure zvikuru kupfuura Neptune nePluto. Parizvino, chinhu chiri kure kwazvo chakawanikwa nespacecraft chave Arrokoth (2014 MU69). Munzvimbo iyo yakatariswa, kune nzvimbo yesolar system inotonhora zvakanyanya uye ine rima uye inonzi Kuiper belt. Kukosha kwayo kuri pakuti ine makiyi ekunzwisisa kuti solar system yakaumbwa sei.
Nokudaro, tichakuudza zvose zvaunoda kuziva nezveKuiper bhandi, maitiro ayo uye mavambo.
Chii chinonzi Kuiper belt
Bhandi reKuiper inzvimbo yakaita sedonut (inonzi Tor in geometry) ine mamirioni ezvinhu zvidiki zvakaomeswa nechando. Zvinhu izvi zvakabatanidzwa zvinodaidzwa kuti Kuiper belt zvinhu.
Iyi inzvimbo yakazadzwa nemamiriyoni emitumbi yemudenga ingadai yakagadzira mapuraneti, zvisinei negiravhiti reNeptune rakakonzera kukanganisa munzvimbo ino. kudzivirira mitumbi miduku iyi yekudenga kuti isauye pamwe chete kuti iumbe nyika huru. Nenzira iyi, bhandi reKuiper rine zvimwe zvakafanana kune makuru asteroids anotenderera Jupiter muzuva.
Pakati pezvisikwa zvekudenga zvakawanikwa muKuiper belt, inonyanya kuzivikanwa ipuraneti diki Pluto. Ndiro mutumbi mukuru wekudenga muKuiper Belt, kunyangwe nyika nyowani (Eris) yehukuru hwakafanana yakangowanikwa muKuiper Belt.
Kusvikira nhasi, Kuiper Belt ndiwo muganhu wechokwadi wechadenga, unozivikanwa zvishoma uye wakaongororwa. Kunyange zvazvo Pluto yakawanikwa muna 1930 uye bhanhi rezvinhu zvechando zvakafanotaurwa kuvapo kunze kweNeptune, zvinofanira kuonekwa kuti asteroid yekutanga munharaunda ino yezuva yakawanikwa muna 1992. Kudzidza uye ruzivo rweKuiper Belt kunokosha. kunzwisisa kwakabva uye kuumbwa kwezuva.
Bumbiro reKuiper Belt
Parizvino, dzakanyorwa anopfuura 2.000 mitumbi yekudenga muKuiper Belt, asi zvinongomirira chikamu chiduku chenhamba yose yemitumbi yomudenga munharaunda iyi yegadziriro yezuva.
Zvinhu zveKuiper bhandi ndeye comets uye asteroids. Kunyangwe iwo akafanana, comets uye asteroids ane akasiyana kuumbwa. Kometi mitumbi yemudenga inoumbwa neguruva, matombo, uye aizi (gasi rakaomeswa nechando), nepo asteroids inoumbwa nematombo nesimbi. Aya matumbi emuchadenga zvisaririra zvekuumbwa kwesolar system.
Zvizhinji zvezvinhu zvinoumba Kuiper Belt zvine masatelliti anozvitenderedza, kana zvinhu zvebhinari zvinoumbwa nezvinhu zviviri zvine saizi yakafanana, uye orbit kutenderedza poindi (common centre of mass). Pluto, Eris, Haumea uye Quaoar ndezvimwe zvezvinhu zvinotakura mwedzi muKuiper Belt.
Parizvino, huremu hwezvisikwa zvekudenga zvinoumba Kuiper Belt zvinongova 10% yehuremu hwePasi. Nekudaro, iyo yekutanga nyaya yeKuiper Belt inofungidzirwa kuva 7 kusvika 10 kuenzana nehukuru hwePasi, uye zvinhu izvo. akaiumba kubva kumapuraneti mana makuru (Jupiter, Saturn, Uranus uye Neptune).
Zvikonzero zvekuderedza kurasikirwa kukuru
Zvinhu zvinowanikwa muKuiper belt zvinodaidzwa kuti KBO's. Kurasikirwa kwehuwandu mubhandi rekudenga rakaoma nechando kunokonzerwa nekukukurwa uye kuparadzwa kweKuiper belt. Iwo madiki comets uye asteroids anoigadzira anodhumhana uye anotsemuka kuita maKBO madiki neguruva, izvo zvinopeperetswa kunze kana kupinda muzuva nemhepo yezuva.
Sezvo bhandi reKuiper richinyura zvishoma nezvishoma, iyi nzvimbo yesolar system inoonekwa seimwe yemabviro emacomets. Imwe nharaunda yekwakabva macomets ndeye Oort gore.
Makometi anobva muKuiper belt anogadzirwa kana marara akaumbwa mushure mekudhumhana kweKBO anodhonzwa musolar system neNeptune's gravity. Makometi anobva muKuiper belt anogadzirwa kana marara akaumbwa mushure mekudhumhana kweKBO anodhonzwa musolar system neNeptune's gravity. Mukati morwendo rwokuenda kuzuva, zvimedu zviduku izvi zvakavharirwa munzira duku negiravhiti reJupiter, iro haina kupfuura makore makumi maviri. Vanodaidzwa kuti short period comets kana comets dzemhuri yeJupiter.
Iri kupi?
Sezvatakambotaura, Kuiper Belt iri munzvimbo yekunze kwesolar system, iyo inotenderera yePluto. Ndiyo imwe yenzvimbo dzakakura kwazvo dzesolar system. Mupendero wepedyo weKuiper Belt uri mukutenderera kweNeptune, kutenderera 30 AU. (AU ndicho chikamu chemuchadenga chechinhambwe, chakaenzana nemakiromita 150 miriyoni, chinova chinhambwe chiri pakati pePasi neZuva), uye Kuiper Belt inosvika makumi mashanu AU kubva kuzuva.
Inopindirana neKuiper Belt uye inowedzera nzvimbo inonzi Scattering Disk, iyo inotambanukira pachinhambwe che1000 AU kubva kuzuva. Bhandi reKuiper harifanirwe kuvhiringika neOort gore. Gore reOort rinowanikwa kunzvimbo iri kure kwazvo yesolar system, munzvimbo iri kure kwazvo, inofungidzirwa kuva pakati pe2000 ne5000 AU kubva kuzuva.
Inoumbwawo nezvinhu zvakaomeswa nechando zvakaita seKuiper belt, yakaita sebhora. Yakafanana nehombe huru, ine zuva uye mapuraneti ose uye zvisikwa zvekudenga zvinoumba sangano rezuva, kusanganisira Kuiper belt. Kunyange zvazvo kuvapo kwayo kwakafanotaurwa, hakuna kucherechedzwa zvakananga.
Ndinovimba kuti neruzivo urwu wakazivisa kuti Kuiper belt chii, misiyano neOort gore uye dzidza zvakawanda nezvechadenga chedu.
