I-satellite "iTroyan" ye-Uranus namanye amaqiniso athakazelisayo mayelana "nabahambi nabo" bale planethi

Kubonakala sengathi uhlelo lwethu lwelanga selufunde kahle, futhi sekuyisikhathi sokuhlola ezinye zezwe. Kodwa kwakukhona! Kuvela ukuthi eduze kwaseMhlabeni ungathola futhi izinto ezimangazayo ezithakazelisayo. Ubufakazi balokhu ukutholakala kwakamuva kwazazi zezinkanyezi zaseCanada ezivela eNyuvesi yaseBrithani Columbia eVancouver . Bathole umngane we-"Trojan "oyingqayizivele we- planet Uranus, kamuva eyathola igama le-QF99 ka-2011. Ngendlela, ngo-2010, eduze neMhlaba, i-star asteroid yokuqala yalolu hlobo nayo itholakale. Igama layo lingu-2010 TK7, futhi ububanzi buyizingamakhulu amathathu.

Yiziphi i-Trojan "asteroids" ezithakazelisayo

Lolu hlobo lwezidalwa zasezulwini luthiwa igama layo ngoba abameleli balo banesici esinqumayo: basendaweni efanayo njengoba amaplanethi ngokwabo, ahlala ngqo eduze kwawo, futhi kungenzeka ukuthi ukushayisana kwabo kushayisana. Lokhu kuzinza kuhlotshaniswa nelungiselelo elikhethekile lezindlela zokuthi "i-Trojans": zidlula amaphuzu aseLagrange, lapho amandla okugwedla amandla ahlangana khona.

Kumele kuqashelwe ukuthi i-satellite evulekile ye-Uranus, etholakala amaCanada, iyona kuphela yohlu lwayo, ngoba kuze kube yilesi sikhathi abaningi be-astrophysicists bakholelwa ukuthi izidumbu ze-cosmic ze-cosmic zalolu hlobo azikwazi ukusebenza. Ngokombono wabo, amandla adonsela phansi kwezinye izinto ezikhona kule ngxenye yesimiso sethu sobusuku ngeke asuse "amaTrojans" ngokuzenzakalelayo ezizindeni zabo. Noma kunjalo, i-satellite entsha ka-Uranus ngeke ishiye indawo yayo yamanje. Sengeza ukuthi ububanzi bale nto ku-cross section ngu-60 km, kanti izingxenye eziyinhloko yi-ice kanye namadwala avame ukutholakala ku-comets.

Abanye "abangane" be-giant azure

I-satellite ngayinye ka-Uranus, njengoba ngempela iplanethi ngokwayo, ijikeleza ngendlela ejikelezayo cishe cishe ehamba ngezindiza ze-ecliptic. Akuncane kakhulu e-Uranus. Kuze kube manje, izazi ze-astrophysicists ziye zathola ama-satellite amancane amahlanu amakhulu futhi angama-satellite amancane kule planethi. Okugqamile kubo yi-Ariel. Okuphambene naye - Umbhalo, kunalokho, ubumnyama kunabo bonke omakhelwane bawo. UTatania, njengoba umuntu angacabangela egameni, yi-satellite enkulu kunazo zonke e-Uranus. Emaceleni ayo kukhona izigodi eziningi kanye neziphambeko kanye nenani elingenamkhawulo lezinsika. Ububanzi bale satellite buyi-1580 km. UMiranda uyisihambi esingaqondakali kakhulu isikhala. Okokugcina kumangalisa abaningi ngesakhiwo sayo: kubonakala sengathi iqukethe amabhlogo amatshe amakhulu amane noma amathathu. Ivala i-Oberon emihlanu ephezulu - i-satellite yesibindi kunazo zonke kunazo zonke ezinkulu ze-Uranus. Ososayensi bazi ngalezizinto zesikhala ngisho nangaphambi kokuba izithombe ezitholakala ku-Voyager-2 zitholwe. Ngenxa yale divayisi, abantu bafunde ngama satellite ayishumi ayisishiyagalolunye, amabili ayo asebenza njengabelusi "emasongweni," njengoSaturn. Futhi ucwaningo lwamuva luvumele ososayensi babone ezinye izinto ezincane zesikhala ezizungeze u-Uranus. Namuhla, inani lama-satellite avulekile liqala ukudlula okweshumi okwesibili, okwenza i-giant giant ibe umholi wesistimu yethu ngokwezinombolo "zabanye abahamba nabo" basezulwini.
