History

Deneb, one of the brightest stars, with an apparent magnitude of 1.25. This star, at about 1,500 light-years’ distance, is the most remote (and brightest intrinsically) of the 20 apparently brightest stars. It lies in the northern constellation Cygnus and, with Vega and Altair, forms the prominent “Summer Triangle.”
