<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: I-Passage: I-Vega iye yafundwa kabanzi izazi zezinkanyezi, okwaholela ekubeni ibizwe ngokuthi ngokungangabazeki inkanyezi elandelayo ebaluleke kunazo zonke esibhakabhakeni ngemva kweLanga. UVega wayeyinkanyezi yasenyakatho cishe ngo - 12 000 B.C. futhi uzophinde abe yinkanyezi yasenyakatho cishe ngonyaka ka - 13 727, lapho ukuncipha kuyoba 8614. UVega waba yinkanyezi yokuqala ngaphandle kweLanga eyathwetshulwa futhi waba ngowokuqala ukuba nombono wayo oqoshiwe. Yayingenye yezinkanyezi zokuqala ezaqhathaniswa ibanga lazo ngokulinganisa i-parallax. I-Vega isebenze njengesisekelo sokulinganisa isilinganiso sokukhanya kwe-photometric futhi ingenye yezinkanyezi ezisetshenziselwa ukuchaza iphuzu le-zero lesistimu ye-photometric ye-UBV. Umbuzo: Yini ebhekwa njengenkanyezi ebalulekile esibhakabhakeni?  <response>: UVega
