Vega

(Alpha Lyrae)
(brightest star in constellation Lyra)

Vega (aka Alpha Lyrae) is the brightest star in constellation Lyra. It is a relatively close star, 25 light-years from Earth, and one of the most luminous stars in the solar neighborhood, along with Arcturus and Sirius. It is very well studied: some of the first spectral measurements were done on Vega, and various standardized magnitude scales were defined so as to take Vega's magnitude as zero (these Vega-based scales now termed the Vega system). Vega's characteristics:
