Vega: First Star to be Photographed (Fact of the Day)

Star Vega
Vega is the fifth brightest star in the sky and the brightest star in the constellation of Lyra. It is about 25 light years away from Earth. Vega is the most studied star after Sun and it's also the first star to be photographed after Sun. It is also the first star whose distance was estimated using the parallax measurements. Vega is estimated to be 2.15 times the mass of our Sun and it's about one-tenth the age of the Sun. Around 14,000 years ago, Vega was used as the north star and our current north star is Polaris.
