Denev
Denebe is a summer triangle with an alphabetical position in the tail of the swan, one of the constellations of summer, a portrait of a lyric poet, and a constellation of an eagle. This star belongs to a blue supergiant star, with an apparent grade of 1.25, the brightest star in the night sky. It belongs to the brightest class of known stars. However, it is not easy to calculate the exact distance and brightness to the Deneb, so the expected brightness range varies from 54,000 to 196,000 times the sun. There are several distinctive names of these stars, which are AriDed and Aridip. Today, however, it is rarely used.
