Vega is the brightest star in the northern constellation of Lyra. It is a blue-white main-sequence star located approximately 25 light-years from Earth.
It is about 2.1 times more massive than the Sun and rotates so rapidly (every 12.5 hours) that it bulges at its equator.
It was the first star other than the Sun to be photographed and is often used as a standard for calibrating the magnitude scale
