Along with Vega and Altair, Deneb is one of the stars of the prominent asterism, the Summer Triangle. |
Vega has a higher apparent magnitude, while Deneb has a higher absolute magnitude. |
Below it, hugging the horizon, is Vega in Lyra, while Deneb in Cygnus lies a bit higher and to the right. |
He'd known he was going to Deneb, Dr. Kalmar thought angrily. |
Just as Deneb is in the tail of Cygnus the Swan in our summer sky, so Denebola, further E, is the tail of Leo. |
First, Altair in Aquila at the bottom tip with Deneb in Cygnus further up and a little to the west, brightest of all, zero mag. |
