Vega is the brightest star in Lyra, and the fifth brightest star in the sky. It is the third brightest star in the Northern night sky, after Sirius and Arcturus, and can often be seen near the zenith in the mid-northern latitudes during the Northern Hemisphere summer.
It will again move to a similar position in around 8,000 years time. Vega is a very important star, and probably the most studied after the Sun. Nearby, at only 25 light-years, it is spinning very rapidly. In fact, it is spinning at 93% of the rate at which it would break up.
