<prompt> I-Vega yayiyinkanyezi yasenyakatho cishe ngo-12,000 BC futhi izophinde ibe njalo ngonyaka ka-13,727, lapho ukwehla kuzoba ngu- 86 14 . I-Vega yayiyinkanyezi yokuqala ngaphandle kweLanga eyathwetshulwa futhi eyokuqala ukuba nombhalo wayo oqoshiwe. Kwakungenye yezinkanyezi zokuqala ibanga lazo elalinganiselwa ngezilinganiso ze-parallax. I-Vega isebenze njengomugqa oyisisekelo wokulinganisa isilinganiso sokukhanya kwe-photometric futhi ingenye yezinkanyezi ezisetshenziselwa ukuchaza iphuzu zero lohlelo lwe-UBV photometric. Umbuzo: Yini ebhekwa njengenkanyezi ebalulekile esibhakabhakeni?  <response>: UVega
