the brightest star in the constellation, which, along with Vega in Lyra to the west and Altair in Orleus to the south, forms the Summer Triangle of Orientation. This bright blue-white supergiant (1.2mag) is much further away than other bright stars in our sky - it lies at a distance of 2600ly. To be this bright from this distance, Deneb must have an energy output greater than 60,000 Suns, making it one of the brightest stars visible to the naked eye (e.g. Vega is 25 and Altair only 11 light years away). Its mass is 19 times and its diameter 203 times that of the Sun. The surface temperature reaches 8500K.
