Deneb

Deneb (also named Arided, αあるふぁ Cygni, alpha Cygni, αあるふぁ Cyg) is the brightest star in the constellation of Cygnus. It, along with Vega, and Altair make up the Summer Triangle asterism.

It has an apparent magnitude of 1.25, which means that it is the 20th brightest star in the night sky. However its distance from the sun and luminosity are difficult to calculate, but it's distance is estimated to be approximately 2,600 light years away. It is thought to be between 55,000 and 196,000 times as luminous as the Sun.^[1]

Deneb is a blue supergiant that is 203 times larger than the Sun.^[2]

Deneb will be the Pole Star in the year 9800 AD.^[3]
