Deneb Quiz – Cygnus, the Summer Triangle and a Supergiant

Deneb is the brightest star in Cygnus, the swan, and its name comes from the Arabic word for tail. It marks the top of the Northern Cross and, with Vega and Altair, forms the Summer Triangle.

Deneb is a white supergiant around 2,600 light-years away, though estimates vary. It is tens of thousands of times more luminous than the Sun, making it one of the most luminous stars visible to the naked eye.

Because Earth's axis slowly wobbles, Deneb will serve as a northern pole star thousands of years from now. The Summer Triangle is best seen on summer and early autumn evenings in the Northern Hemisphere.
