(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 and some of the first
spectral measurements were done on Vega,
and various magnitude measurements were originally
scaled to Vega being 0.
