UVesta - Ibhanti lubonakale ngeliso lenyama

UVesta - Ibhanti, ngeendlela ezininzi ezibangel 'umdla. Yiyo loo nto kuphela ukuze sibonwe ngeliso lenyama. Ngokobunzima, kunye nobukhulu UVesta mkhulu kakhulu ezinye izijikelezi eyaziwa kwisithuba phakathi umzila kaZeyus ne Mars. Ngu parameters awo kude kufutshane yiplanethi encinane. Akhiwe ibhanti engundoqo ke, ilitye, UVesta ubhekisela imizimba eyenziwe yajikeleza kwixesha elinye njengoko uMhlaba, yaye ngoko, na onokumxelela okuninzi malunga elidlulileyo elikude kwinkqubo yethu.

lokufumanisa

UVesta - Ibhanti, wafumanisa kwinkqubo ukufuna iplanethi phakathi iMars Jupiter. Ngokutsho ithiyori, ukusasazwa wezijikelezi kwi isithuba esirhangqe ilanga ixhomekeke imithetho ethile. Zonke eyaziwa ekuqaleni kwenkulungwane XIX ihlabathi angena kulo mbono. Le ngaphandle kuphela uJupiter Mars. Isithuba omkhulu phakathi kwawo ukufihla emhlabeni engaziwayo. Ngexesha kwakhe ngenxa ezininzi iziqalelo ze Main kwafunyanwa ibhanti asteroid.

UVesta wafumanisa ngo 1807 ngu Heinrich UWilhelm Olbers. Enye ingcali yenzululwazi, uCarl GAUSS, wamnika igama uthixokazi laseRoma ezonka. Igama kwahlala kwaye isasetyenziswa nangoku namhlanje.

parameters

Emva eCeres kwaziwe ukuba kwiiplanethi ezincinanana, UVesta ubukhulu sele kwindawo yesibini phakathi izijikelezi emva Pallas. parameters zayo - 578 × 560 × 458 km. asymmetry olubonakalayo isimo, nto leyo ethi ithintele kukhokelela yiplanethi encinane. Ngokobunzima (2.59 × 10 ²⁰ kg) oko phambili kwaye palladium, oko kukuthi, ibhanti engundoqo asteroid bubalaselayo kule parameter, kodwa zonke eCeres efanayo.

Ngaba eli litye UVesta umoya?

Asteroids azikho nje lubalasele udidi imizimba yasezulwini. Ukusuka iiplanethi ahluke kwinani yemida: ubukhulu, imilo, ubunzima njalo njalo. Iimpawu Ibhanti, akazange avumele ukuba ukubamba yemvulophu igesi. Ngoko ke impendulo yombuzo "Ngaba eli litye UVesta, nomoya" - negative. Kakhulu iqokobhe tenuous yerhasi ikhona kwi Ceres. Amanye amaqumrhu kwindawo engundoqo akakwazi ndoqhayisa iimpawu ezifana eli litye UVesta. It has emoyeni kobasemhlabeni, Venus, Mars, iingxilimbela igesi kunye nabanye abahlobo. Asteroids kuba incinci kakhulu.

Indlela ukubona asteroid UVesta?

UVesta ngenxa yobumhlophe kungabonwa ngeliso lenyama. Nangona enasilela ubukhulu eCeres nguPallas, kodwa lubonakala ngokuba reflectivity enkulu. Ezinye izijikelezi ne Umhlaba ngeke azabonakala ngaphandle nezixhobo ezizodwa.

Elona xesha lifanelekileyo uphendle izijikelezi zezulu - iintsuku inkcaso, xa efika kumgama omncinane uMhlaba. Ngexesha la maxesha, isilungiseleli seglosi yayo luyanda ukuya m 5,1 (ixabiso elincinane le parameter - 8,5 m). ngexesha lokugqibela kukumelana oko kwenzeka ngo-Apreli 2014.

UVesta usondele kumgama omncinane ukuba iplanethi yethu kanye qho emva kweminyaka 3-4. Ngaphandle iteleskopu basigcine kunokwenzeka kuphela kwiimeko ngokubonakala elungileyo. Kulo mzekelo, oku ayahlukanga kweenkwenkwezi eziqhelekileyo.

motion

Komzila UVesta kuxhomekeke kwinxalenye engaphakathi ibhanti main asteroid. ukuma kwawo kancinci kuphela eyandisiweyo - phantse isangqa ogqibeleleyo. Komzila lubonakala ngokuba ukuthambeka kancinane kwi-moya baza. UVesta yenza revolution enye ngeenxa kweLanga kwiminyaka 3.6. Ngelo xesha linye ngexesha intshukumo orbit kwabo planethi ayiwelanga umgca eli litye.

Space probe Dawn

Ngo-2011, ngoJulayi, UVesta wadlula kwinqanaba kumgama omncinane ukusuka emhlabeni wethu. Eli thuba landisiwe ukuya esisetyenziselwe isifundo eneenkcukacha eli litye. Emva ngo-2007, ndaya UVesta, Dawn AMC. Injongo unit - ukufunda eli litye, kwaye yiplanethi encinane Ceres.

A emzileni setyhula UVesta Dawn weza July 16, 2011. NgoDisemba 12, kuye kwafikelelwa ephakame ubuncinane phezu asteroid. Phakathi wemisebenzi iyunithi aba nomlinganiselo yentsimi omxhuzulane, ukuqingqwa lwaseNtshona Koloni ziba neutron nama-ekhatywayo nth ingcambu reyi evela kwi kokuwa reyi yesiqalo kwi eli litye UVesta. Iifoto yenjongosenzi yaqala ukuza Umhlaba on December 13.

Dawn AMC walishiya eli litye -5 Septemba 2012 yaye waya Ceres. Ukuza kuthi ga ngoku (Disemba 2015), umatshini iyaqhubeka ukusebenza ngomhla komzila yiplanethi encinane.

showplace

UVesta - Ibhanti ngenyameko "kuhlola" iteleskopu "Hubble". Izifundo zabanjwa-imi- 90 kwinkulungwane yokugqibela. "Hubble" uye wafundela phezu eli litye. Le nxalenye onomtsalane isiqabu waba wentaba enkulu, kamva igama rheasilvia. Okulandelayo, mhlawumbe eshiyeke le ngozi, iphawulwa ububanzi of km 460 kunye nobunzulu km 13. Izazinzulu akakwazi ukuphendula umbuzo indlela UVesta nako ukusinda ngesibetho enjalo.

Dawn AMC nayo yafunda urhulumente kuloo mngxuma. Ngokutsho imibono izazinzulu rheasilvia engange kwezigidi eyadlulayo. Pool mngxuma ngokuyinxenye efihla, azafunyanelwa ndawo nempembelelo ngakumbi yamandulo, wentaba ogama Veneneyya. Xa iziko rheasilvia oko intaba-22 km aphezulu 180 km ubukhulu. Ngu parameters awo ngaphambi bakaRafa Olympus kwiMars, ngaphambili ingqalelo le ntaba iphakamileyo eyaziwa kwinkqubo elanga.

Izazinzulu bacinga ukuba izinto betekisi yi ukothuka, waba izinto ngenxa kukuvela izinto kunye nosapho iklasi UVesta izijikelezi V.

Abaphandi ingqalelo yakhe ukuba izinto ezifana njengoko na onokumxelela okuninzi malunga nexesha xa inkqubo elanga wabumba. UVesta - Ibhanti, ukwakhiwa kwayo kakhulu iiplanethi Umhlaba-like. Kungenzeka, kuya kukuxelela ngeenkwenkwezi ukuba ukufunda ezininzi mandulo zikude iqhekeza lethu le Galaxy.
