Location: 20h 41m 25.9s (right ascension), +45°16’49” (declination) This means that some parts of their stellar surface are contracting while others simultaneously expand. The star Deneb (also known as Alpha Cygni or Arided) is a blue-white spectral class A2 … In another version of the tale, Zeus turned himself into a swan to trick the goddess Nemesis into giving him shelter. Would Scientist 1 be likely to claim that this protostar that has grown to 8 Ms is a supergiant star like Deneb?F. Deneb, is one of the most distant stars we can see without optical aid. With a great apparent brightness and because it can be observed for most of the year at northern latitudes, Deneb can be easily studied spectroscopically with small or moderate aperture telescopes. 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. In the Alfonsine Tables, compiled in Spain in the 13th century, Deneb was listed as Denebadigege. The “white” designation means that its surface is thousands of degrees hotter than the Sun’s. Deneb marks the tail of the celestial Swan and the top of the Northern Cross. Deneb, also called Alpha Cygni, is one of the most familiar stars in the night sky, as well as one of the most distant luminous stars that can be clearly viewed by the unaided eye, with an apparent magnitude of 1.25. 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. Deneb is a blue supergiant that is 203 times larger than the Sun. She later became famous as Helen of Troy. Polaris, the current North Star, is a much better indicator of true north, being located within 0.5° of the pole, but at magnitude 1.98, it is also considerably fainter than Deneb. Deneb is a white supergiant. With an average visual magnitude of 1.25, it is the brightest star in the constellation Cygnus and the 19th brightest star in the sky. In Chinese folklore, Deneb is associated with the myth of the cowherd and the weaver girl (represented by Altair and Vega), two separated lovers who can only reunite once a year, and the star marks the magpie bridge which allows them to meet. Cygnus also contains the red supergiant or hypergiant NML Cygni, one of the largest stars known. As a blue-white supergiant (A2Ia), Deneb is one of the biggest white stars known, and is 203 times bigger than the Sun, and around 19 times more massive. Deneb is part of two large asterisms that dominate the evening sky during the northern hemisphere summer. Deneb will be the North Pole star (the nearest visible star to the north celestial pole) around the year 9800 AD, but as it will only come within 7° from the pole, it will not really mark true north. 4. With an average visual magnitude of 1.25, it is the brightest star in the constellation Cygnus and the 19th brightest star in the sky. Deneb is labeled on the H-R diagram as being at an A2 classification, meaning it is very hot .

It has now stopped fusing hydrogen at its core, but its next stage of evolution is difficult to know. It is one of the Greek constellations, listed by the Greco-Roman astronomer Ptolemy in his Almagest in the 2nd century CE. Cygnus constellation itself is sometimes referred to as the Northern Cross, much like Crux in the south is known as the Southern Cross, even though the constellations contain more stars than those forming the asterisms. Also found in Orion is the red supergiant star called Betelgeuse. Some of the best known fictional uses of the star include Dan Simmons’ 1989 novel Hyperion, Anne McCaffrey’s “The Tower and the Hive” series, The Silver Surfer comic book series, the pilot episode of Star Trek: The Next Generation (“Encounter at Farpoint”) and the TV series Blake’s 7 and Babylon 5. Deneb is classified as a white supergiant. Answer to: What color is Deneb? In the sky the star appears to us as the most brilliant nineteenth, immediately after Pollux and Formalhaut.

Deneb is a true supergiant, its diameter, calculated from its temperature and luminosity, is 108 times that of the Sun, half the size of Earth's orbit. It was even hotter earlier in its life when it was in the main sequence. Among the 30 brightest stars in the sky, Deneb is by far the most distant, by a factor of almost 2. The “white” designation means that its surface is thousands of degrees hotter than the Sun’s. 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. Deneb - α Cygni (alpha Cygni) Deneb, also designated as α Cygni (alpha Cygni), is a variable and double supergiant star in the constellation of Cygnus.

It is the brightest star in Cygnus and the 19th brightest star in the night sky, with an average apparent magnitude of +1.25. 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! It is currently either cooling and expanding to become an exceptionally luminous red supergiant or it will become a luminous blue variable (LBV) or possibly a Wolf-Rayet star.

Helen and Polydeuces were the immortal children of Zeus, and Clytemnestra and Castor were Tyndareus’ children and therefore mortal. Deneb is the prototype of a class of stars known as Alpha Cygni variables. It is 19 times more massive than the Sun and has expanded to a size of 203 solar radii. Deneb is so bright, that it actually rivals … Deneb is a blue-white supergiant star of spectral type A2 la. Deneb . Based on an early analysis of the Hipparcos satellite measurements carried out in the early 1990s, Deneb’s given distance from Earth was about 2,615 light years or 802 parsecs. Deneb is by far the most distant star of the Summer Triangle, but only the second in brightness, after Vega. In fact, some recent measurements say it could be 200 times the diameter of the Sun. Similar small-scale rapid fluctuations have been observed in many early supergiants. A white supergiant star, Deneb is located in the constellation of Cygnus.. History and Cultural significance. It will have a relatively short life and probably go out in a supernova explosion within the next few million years.

Bright stars are at the top and faint stars are on the bottom. Similar variability has been observed in many luminous blue variables during their hot phases, but these stars are normally classified as LBVs. Deneb is an average-sized world with a dense atmosphere tainted with the by-products of its extensive industrialization. Hipparcos measurements of Deneb’s parallax gave the value of 1.01 ± 0.57 milliarcseconds, which was consistent with the distance of 2,600 light years, but a more recent study indicates a considerably larger parallax and significantly smaller distance. Image: Torsten Bronger. 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.
