Tab sis Kuiper Belt thiab cov Oort Huab muaj ntau tshaj qhov xav paub nyob deb. Lawv yog cov pristine remnants ntawm lub nebula uas tag nrho lub hnub ci system tau tsim. Lawv muaj pes tsawg leeg thiab faib chaw tseem ceeb kev txwv ntawm cov qauv ntawm cov evolution thaum ntxov ntawm lub hnub ci system.
Ntawm no, vim li cas Oort Cloud tseem ceeb?
Cov Oort Huab yog roughly spherical, thiab xav tias yog lub hauv paus chiv keeb ntawm feem ntau ntawm lub sij hawm ntev comets uas tau pom. Qhov no huab ntawm cov hais yog theorized los ua cov seem ntawm cov khoom siv uas tsim lub hnub thiab cov ntiaj chaw. Astronomers tam sim no xa mus rau cov khoom tseem ceeb no raws li ib tug protoplanetary disk.
Vim li cas Kuiper Belt tseem ceeb? Cov Kuiper Belt tuav qhov tseem ceeb rau txoj kev tshawb fawb ntawm lub planetary system ntawm tsawg kawg yog ob theem. Qhov thib ob, nws yog dav ntseeg tias lub Kuiper Belt yog lub hauv paus ntawm lub sij hawm luv luv comets. Nws ua raws li lub chaw cia khoom rau cov cev no ib yam nkaus uas Oort Cloud ua raws li lub chaw cia khoom rau lub sijhawm ntev ntawm cov comets.
Kuj kom paub, qhov txawv ntawm Kuiper txoj siv thiab Oort huab yog dab tsi?
Cov Kuiper huab , uas yog feem ntau hu ua Kuiper siv , yog ib cheeb tsam zoo li disk uas pom dhau Saturn lub orbit. Cov Oort huab yog ib qhov loj ntawm trillions ntawm comets thiab hmoov av uas ncig lub hnub. Cov Oort huab cov khoom raug tsim los ze rau lub hnub tshaj li qhov Kuiper siv khoom.
Txoj siv Kuiper thiab Oort huab daim ntawv li cas?
Thaum lub hnub ci tsim, ntau cov pa roj, plua plav thiab pob zeb rub los ua ke daim ntawv lub hnub thiab ntiaj chaw. Cov Kuiper Belt thiab nws compatriot, qhov ntau nyob deb thiab kheej kheej Oort Huab , muaj cov khoom seem tshuav txij thaum pib ntawm lub hnub ci thiab tuaj yeem muab kev nkag siab zoo rau nws txoj kev yug.

Vim li cas lub prime meridian thiab equator tseem ceeb?
Los ntawm kev siv txoj kab nruab nrab thiab thawj meridian, peb tuaj yeem faib lub ntiaj teb ua plaub hemispheres, sab qaum teb, sab qab teb, sab hnub tuaj, thiab sab hnub poob. Piv txwv li, lub tebchaws United States nyob rau sab hnub poob Hemisphere (vim nws yog sab hnub poob ntawm lub prime meridian) thiab kuj nyob rau sab qaum teb Hemisphere (vim nws yog sab qaum teb ntawm txoj kab nruab nrab)
Txoj siv Kuiper thiab Oort huab daim ntawv li cas?
Thaum lub hnub ci tsim, ntau cov pa roj, plua plav thiab pob zeb rub los ua lub hnub thiab cov ntiaj chaw. Lub Kuiper Belt thiab nws cov neeg nyob ib puag ncig, qhov deb thiab kheej kheej Oort Cloud, muaj cov seem seem txij thaum pib ntawm lub hnub ci thiab tuaj yeem muab kev nkag siab zoo rau nws txoj kev yug
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Qhov twg nyob deb Kuiper txoj siv lossis Oort Cloud?
Txoj siv Kuiper thiab cov kab tawg tawg, lwm ob lub reservoir ntawm trans-Neptunian cov khoom, yog tsawg tshaj li ib txhiab li deb ntawm lub hnub raws li lub Oort huab. Qhov kev txwv sab nraud ntawm Oort huab txhais tau hais tias thaj tsam cosmographical ntawm lub Hnub Ci System thiab qhov ntev ntawm lub hnub lub roob
