Location of Vega

The fifth brightest star in the sky, Vega is easy to find in northern summer skies. It is accompanied by four stars in a parallelogram shape that make up the body of the Lyre, the distinctive constellation of Lyra.

Vega has only about three times the diameter of the Sun, though it is somewhat hotter and more luminous. It lies very close by in galactic terms, at about 25 light years, and so is a brilliant object in the night sky.
