Look it up now! Deneb, is one of the most distant stars we can see without optical aid. Vega and Altair, the other two stars of the Summer Triangle, are also members of this special group. So it’s only a simple matter of logic to deduce that if a light source appears to be very bright, but is also known to be very far away, it must possess great luminosity. Names similar to Deneb were given to a number of bright stars that mark the tail of the animal their constellations represent, from Deneb Kaitos in Cetus (the Whale) and Deneb Algiedi in Capricornus (the Goat) to Denebola, the second brightest star in Leo (the Lion) constellation. 2.48), Fawaris (Delta Cyg, mag.

What is known about Deneb is that it’s a blue-white supergiant star that is furiously fusing its massive stocks of thermonuclear fuel and producing enough energy to make this star somewhere between 50,000 and 190,000 times brighter than our Sun if they were viewed at the same distance! Deneb – Sun comparison, image: Uwe Dedering (Wikimedia Commons). It is only slightly fainter than Pollux in the constellation Gemini and Fomalhaut in Piscis Austrinus, and it just outshines Mimosa in Crux and Regulus in Leo. Similar variability has been observed in many luminous blue variables during their hot phases, but these stars are normally classified as LBVs. Of spectral class A2Iae, it places in the range of the most brilliantly intrinsic stars. It also may also have a single line spectroscopic binary star in its system; however, further studies need t… Because Deneb has used up it’s hydrogen supply and is now fusing heavier elements, it has left it’s main sequence phase and it currently a blue-white (very hot) supergiant and should be expanding into a red supergiant but it’s evolutionary future is currently unclear. Alpha Cygni is a blue-white supergiant with 20 solar masses and 200 times the radius of the Sun. It was discovered by O. J.
