Historically, Deneb’s Arabic name is derived from the phrase Al Dhanab al Dajajah meaning, “Tail of the Hen.” This dates back to the first interpretation of this constellation as a chicken rather than a swan. It serves as a prototype of other stars in this range known as the Alpha Cygni variables. Once the month of August rolls around, Deneb is high in the night sky and ready for full viewing. Deneb's adopted distance from the Earth is around 802 parsecs (2,620 ly). A personalized star registration in the Online Star Register is widely considered one of the most original, emotional, and personal gifts you can give to your partner, a friend, family member, or coworker. This will eventually evolve Deneb into a very luminous red supergiant and after a few million years its core will collapse producing a supernova. Deneb is the brightest star in “the Swan” marking the point on its hind end where the feathers begin to grow. Deneb is not just another twinkling celestial object, it has some cold hard facts and true significance.

As a result of strong stellar winds, it loses about a millionth of a solar mass each year.

The Sun's radius is 695,800km, therefore the star's radius is an estimated 164,137,528.53.km. The best time to view Deneb in the northeastern horizon is mid-evening starting in the spring months.
Deneb is one of the largest white stars known today. So if you have a chance to view this fascinating star of “the tail of the bird” be sure to check it out. It is 19 times more massive than the Sun and has expanded to a size of 203 solar radii. It also may also have a single line spectroscopic binary star in its system; however, further studies need to be done to confirm this theory. It shines with an apparent visual magnitude of 1.25 and an absolute magnitude of -8.4 making it approximately 200,000 times more luminous than the Sun. Alpha Cygni is a blue-white supergiant with 20 solar masses and 200 times the radius of the Sun. This star is also in the process of changing as it has exhausted all the hydrogen at its core and is currently expanding.

Deneb is the brightest star in the Cygnus constellation and the 19th overall in the night sky. The spectral type of Alpha Cygni is A2la. Because this star is so bright it can be viewed by the unaided eye and is in fact one of the furthest stars that can be seen without a telescope. This star can be seen in its home constellation located in the fourth quadrant of the Northern hemisphere, specifically between latitudes of +90 and -40 degrees.

Deneb is a blue-white supergiant of the spectral type A2 Ia. Online Star Register (OSR) believes that every person on earth should enjoy their very own star in the night sky. 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. The star has a mass about 19 times that of the Sun.

After a few million years Deneb’s core will collapse producing a supernova. In Chinese mythology Deneb is the bridge of magpies a Princess crosses. Deneb is from the Latin language meaning ‘tail’, and is one of the largest white stars known today. Alpha Cygni is burning with a surface temperature of 8,500 Kelvins or 14,840 degrees Fahrenheit (8,226 degrees Celsius). With an estimated temperature of 8,525 K, it is 196,000 times more luminous than the Sun. It marks the top (or head) of the Northern Cross and also one of the three stars in the Summer Triangle.

When searching for Deneb there are three distinct places to locate this bright beauty. This image splits the difference and shows Deneb with a radius 250 times that of the Sun.

If you need the diameter of the star, you just need to multiple the radius by 2. It also has been referred to as Uropygium (according to Richard Hinkley Allen) which means the hind end of the bird where the feathers grow or in modern day terms, “the Pope’s Nose.” In Chinese mythology Deneb represents the bridge of magpies that the Princess (the star Vega) crosses once a year to visit her beloved cowherd (the star Altair). Estimates for Deneb’s radius range from 200 to 300 times that of the Sun.

It also occupies about 804 square degrees in the night sky and belongs to the Hercules family of constellations. This will eventually evolve Deneb into a very luminous red supergiant and after a few million years its core will collapse producing a supernova. Deneb Radius Deneb estimated radius has been calculated as being 235.90 times bigger than the Sun. This star is also in the process of changing as it has exhausted all the hydrogen at its core and is currently expanding. OSR has been naming stars for people all around the world since the start of this millennium and is now the number one star register service in the world. This constellation is the 16th in size (out of the 88) and is home to two Messier, two meteor showers and the famous Northern Cross asterism. It will have a relatively short life and probably go out in a supernova explosion within the next few million years.

These methods give different distances, and all have significant margins of error.

The original derivation of a parallax using measurements from the astrometric satellite Hipparcosgave an uncertain result of 1.0… Deneb is one of the largest white stars known today. It is also called Alpha Cygni and is a blue-white supergiant with 20 solar masses and 200 times the radius of the Sun. Deneb is located around 2,600 light-years away in the constellation of Cygnus (the swan). That’s why we make it possible for you to name a star in the Online Star Register!
