The north pole of Mars points to the midpoint of the line connecting Deneb and the star Alderamin.[34]. This is derived by a variety of different methods, including spectral luminosity classes, atmospheric modelling, stellar evolution models, assumed membership of the Cygnus OB7 association, and direct measurement of angular diameter. Deneb Algedi (Delta Capricorni) is a binary system in the zodiac constellation Capricornus which has a combined apparent magnitude of +2.81, making it the brightest star in the constellation. [9] The IAU Working Group on Star Names has recognised the name Deneb for this star, and it is entered in their Catalog of Star Names.[10]. Deneb Algenub has at least 2 Extrasolar Planets believed to be in orbit around the star. The constellation Cygnus with Deneb at the tail of the swan (top) and Albireo (the double star) at the nose of the swan (bottom). USS Arided was a United States Navy Crater-class cargo ship named after the star. In the southern hemisphere, Deneb is not visible south of 45° parallel south, so it just barely rises above the horizon in South Africa, southern Australia, and northern New Zealand during the southern winter. It lies in the northern constellation Cygnus and, It is the brightest star in Cygnus and the 19th brightest star in the night sky, with an average apparent magnitude of +1.25. It is one of the largest white 'A' spectral type stars known. Since 1943, its spectrum has served as one of the stable references by which other stars are classified. Is the deneb star a binary or multiple star system. About half of star systems are binary star systems. It is now known that red supergiants up to a certain mass explode as the commonly seen type II-P supernovae, but more massive ones lose their outer layers to become hotter again. Examples include several episodes of the Star Trek TV series, the Silver Surfer comic book, the Rush albums A Farewell to Kings and Hemispheres, the Descent: FreeSpace – The Great War computer game, Stellaris, science fiction novel Hyperion, and Andy Weir, in his novel The Martian.

Deneb (Alpha Cygni) is the most luminous star in the constellation Cygnus, and with an apparent magnitude of +1.25, it is the 19th most luminous star in the entire night sky.

Other notable stars are Alpha Ceti or Menkar, Tau Ceti and the famous variable star Mira. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. [14] It never dips below the horizon at or above 45° north latitude, just grazing the northern horizon at its lowest point at such locations as Minneapolis, Montréal and Turin. α 1 Capricorni e α 2 Capricorni (Al Giedi ou Algiedi), binaria óptica composta por dúas estrelas de cor amarela e laranxa.
