Masayendisiti atanga kutsvaka nechegumi yemapuraneti zuva nenyika dzinotenderera pariri

Gore rakapera, takadzidza kuti repfumbamwe nyika angave akavanda rokunze miganhu redu renzou. Asi ikozvino masayendisiti akatanga kutaura chii vanogona kuva maviri.

The vakacherechedza anomalies

Kate Wolf uye Renu Malhotra of Lunar uye Planetary Laboratory paUniversity of Arizona vaidzidza vane tinoguma kubudiswa muna Astrophysical Journal. Mariri, masayendisiti yakawana nzvimbo matombo Kuiper bhandi - nzvimbo mhiri muchadenga pamusoro Neptune. Kufamba mamwe mitumbi izvi zvinoratidza kuti dzimwe zvisingaoneki nyika vatingakurudzira muchadenga yavo.

"The ungangotarisa tsanangudzo zvawanikwa izvi - ndiyo kuvapo vamwe vakawanda zvisingaoneki", - akati Kate Wolf, uyo ari kutungamirira munyori kudzidza.

Zvatinoziva pamusoro tsvagai chegumi nyika

By uremu iyi tsvagai chegumi nyika ingava chinhu chiri pakati Panyika uye Mars. Zvinonzi zvakare vaifungidzira kuti zvinofanira kuva pedyo Sun pane rechipfumbamwe nyika. Masayendisiti dzaona kuti muchadenga ane tsvagai chegumi nyika iri pamusoro 60 nguva kure kubva Sun pane Pasi (kureva, chinhambwe 60 AU, kana muchadenga muzvikamu). Yechipfumbamwe nyika Zvinodavirwa kuti riri kure 500 kusvika 700 AU.

Masayendisiti atanga kutaura nezvokuvapo wegumi nyika pashure pokudzidza 600 Kuiper bhandi zvinhu. Vamwe vavo sokuti kuva "akaremara" muchadenga, ndiko tilted kubudikidza madhigirii sere orbital ndege kuti mapuraneti mikuru iri renzou.

Maererano nevaongorori, yakanakisisa nzira kutsanangura deformation ichi - kutora kuvapo zvimwe zvisingazivikanwi nyika. Panguva iyoyowo, wepfumbamwe nyika, ane gobvu ndiro zvichipomerwa 10 nguva mukanyiwa the Earth, iri hafu vazhinji Neptune, havagoni kutsanangura kuchengetwa anomaly.

The wepfumbamwe nyika, maererano masayendisiti, riri kure kuti sei izvi Kuiper Belt zvinhu. Nechegumi nyika Zvechokwadi anofanira iri kwete kupfuura 100 AU, kuti yekudyidzana kukanganisa Kuiper bhandi zvinhu mukati Range ichi.

tsvakurudzo tsoropodzo

Chokwadi, izvi hazvirevi kuti nyika rechigumi iripo, sokutaurwa mamwe masayendisiti. Somuenzaniso, Alessandro Morbidelli of Observatory of Côte d'waAzuri muna Nice (France) kumbopikisa kuti rakadaro pedyo uye yakajeka nyika aigona rwakaonekwa kusvikira iyoyo.

Zvisinei, masayendisiti uyo aidzidzisa kuti tichiri hatina kuwana chegumi nyika, nokuti inogona iri rizere nechepakati zvikamu Gwara Way. Kana ukatarira Earth, munzvimbo kunogona kuonekwa yakawanda nyeredzi, izvo kuchidzivisa kutarisana ongororo yayo.

An nzira tsananguro

Asi pane imwe tsananguro yacho akacherechedza anomalies. Deformation of muchadenga vamwe Kuiper Belt zvinhu zvinogona kutsanangurwa pokudzora kupfuura nyeredzi "pedyo". Kunyange zvakadaro, izvozvo aizouya pedyo Kuiper bhandi mune pfungwa okupedzisira mamiriyoni 10 apfuura, izvo zvinoita sezvisingaiti.

Zvinotarisirwa kuti zuva nenyika dzinotenderera pariri anogona nekufukidza nyika zvisingazivikanwi kwatiri. Nechegumi nyika sezvo wepfumbamwe, kungava chiduku chikamu kwechakavanzika chakanga tine asi kuongorora.
