'''Vega''' (α Lyr, α Lyrae, Alfa Lire) je najsvetlejša zvezda v [[ozvezdje|ozvezdju]] [[Lira (ozvezdje)|Lire]] ({{jezik-la|Lyrae}}), 5. najsvetlejša zvezda na nočnem nebu in 2. najsvetlejša na severni nebesni polobli, za [[Arktur]]jem. Je [[seznam najbližjih zvezd|zelo blizu]] [[Osončje|Osončju]] (25 [[svetlobno leto|svetlobnih let]]), in, skupaj z Arkturjem in [[Sirij]]em, ena najbolj svetlih zvezd v Sončevi soseski.
 
Vrstica 8 ⟶ 56:
Ime Wega (pozneje Vega) prihaja iz približne transkripcije [[arabščina|arabske]] besede ''wāqi‘'', ki pomeni »padati« ali »pristati«, preko fraze ''an-nasr al-wāqi‘'', »padajoči orel«. Ime nima nobene povezave s slovenskim znanstvenikom [[Jurij Vega|Jurijem Vego]].
