what type of star is deneb

DENEB (Alpha Cygni). Deneb is a blue-white supergiant star of spectral type A2 la. One of the truly great stars of our Galaxy, a class A (A2) supergiant, Deneb serves a three-fold role among the constellations.Its very name tells the first. Fixed Star Deneb Adige Astrology. Along with Vega and Altair, Deneb is one of the stars of the prominent asterism, the Summer Triangle. Deneb is a main star in the constellation Cygnus and makes up the constellation outline. Deneb (/ ˈ d ɛ n ɛ b /) is a first-magnitude star in the constellation of Cygnus, the swan.Deneb is one of the vertices of the asterism known as the Summer Triangle and the "head" of the Northern Cross.It is the brightest star in Cygnus and the 19th brightest star in the night sky, with an average apparent magnitude of +1.25. Bob King Based on the spectral type (A2Ia) of the star, the star's colour is blue - white . Deneb shines bright in the constellation Cygnus. Deneb is the 19th brightest star in the night sky and is the brightest star in Cygnus based on the Hipparcos 2007 apparent magnitude. Its surface undergoes non-radial fluctuations, which cause its brightness and spectral type to change slightly. Some of the most known are the 7 Pleiades, Rigel and Deneb. All three vertices of the Summer Triangle are bluish-white stars, belonging to the spectral class A. Deneb is so bright, that it actually rivals Rigel as the most luminous first magnitude star. Deneb, on the other hand, is located at a distance of 3,550 light years from the solar system.It is the most distant first magnitude star, and its brightness is greatly diminished by the distance. Such is the case with Deneb, a 1st magnitude star and one of the most distant stars you can see without optical aid. It is a variable star (its apparent brightness varies) and is considered an Alpha Cygni-type star. it is one of the vertices of the Summer Triangle and forms the 'head' of the Northern Cross. [2] Since Deneb is very far away, its exact luminosity is hard to calculate but estimates suggest that it is between 55.000 to 196.000 times brighter than our sun. For two stars, Rigel and Deneb, luminosity is shown below: Bolometric luminosity (entire spectra, including non-visible light): Sol - 1 Rigel - 120 000 Deneb - 200 000 Delta Capricorni (δ Capricorni, abbreviated Del Cap or δ Cap) is a multiple star system about 39 light-years away in the constellation of Capricornus (the Sea Goat).The primary star in the system is a white giant and the combined light of its members makes it the brightest star in the constellation.. Deneb is the prototype of a class of variable stars known as Alpha Cygni variables. Deneb is a bluish-white supergiant around 200 times the size of the Sun and burning through its fuel at a rapid rate. The Deneb star Deneb is the brightest star in the constellation Cygnus. Luminosity of such a star is very powerful. [1] Favorable for artistic and scientific pursuits which are carried out with the aim of gain. It is the 19th brightest star in the night sky, with an apparent magnitude of 1.25 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. Deneb is the 19th brightest star as seen from Terra, it is the 26th brightest star in the galaxy, and one of the brightest in Charted Space.
