Kule ndima enikeziwe, khetha igama lengalo yeMilky Way Galaxy lapho isimiso sethu sonozungezilanga sikhona khona
Context:I-Milky Way iyi-galaxy ene-barred spiral ene-D25 isophotal diameter elinganiselwa ku-26.8 ± 1.1 kiloparsecs (87,400 ± 3,590 light-years), kodwa kuphela cishe iminyaka eyi-1,000 yokukhanya emagxeni we-spiral (ngaphezulu kokugqwala). Ukufanisa kwamuva nje kusikisela ukuthi indawo enomzimba omnyama, futhi equkethe ezinye izinkanyezi ezibonakalayo, ingase ibe nobubanzi obucishe bube yiminyaka-kukhanya eyizigidi ezimbili (613 kpc). UMthala uneminyele eminingana eyiziphuphutheki futhi uyingxenye yeQembu Lezinkanyezi Lasendaweni, eliyingxenye ye-Virgo Supercluster, yona ngokwayo eyingxenye ye-Laniakea Supercluster.  Kulinganiselwa ukuthi iqukethe izinkanyezi eziyizigidi eziyizinkulungwane eziyikhulu namakhulu amane okungenani nenani elifanayo lamaplanethi. ISolar System itholakala ebangeni eliyiminyaka engaba ngu-27.000 yokukhanya (8.3 kpc) ukusuka eGalactic Center, emaphethelweni angaphakathi e-Orion Arm, enye yezinhlanganisela zegesi nothuli ezimise okwe-spiral. Izinkanyezi ezisemkhathini ongaphakathi kakhulu okungamamitha-skwele ayizinkulungwane eziyishumi zakha isigaxa esisodwa noma ezengeziwe ezikhishwa yilesi sigaxa. Isikhungo seGalactic siwumthombo omkhulu womsakazo owaziwa ngokuthi iSagittarius A*, umgodi omnyama omkhulu kakhulu onobunzima obungu-4.100 (± 0.034) wezigidi zamandla elanga. Izinkanyezi namagesi ahlukahlukene asuka enkabeni yomthala ahamba ngesivinini esingamakhilomitha angu-220 ngomzuzwana. Ijubane lokujikeleza elingaguquguquki libonakala liphikisana nemithetho ye-Keplerian dynamics futhi lisikisela ukuthi ingxenye enkulu (cishe i-90%) yesisindo se-Milky Way ayibonakali ngezibonakude, ayikhiphi futhi ayimunci imisebe kagesi. Lo mthamo oqagelwayo uye wabizwa ngokuthi "into emnyama". Isikhathi sokujikeleza cishe siyiminyaka eyizigidi ezingu-212 emzileni weLanga.
Isimiso sethu sonozungezilanga sitholakala ku-Orion Arm of Milky way Galaxy.
