List of binary stars

Stars are extremely common in some geographic locations as to others they may rarely be seen. The numbers of stars is considered by some infinite as there is no solid substantial actual number of stars within the universe that scientists binary conclude today. Binary, there are a few stars that are more common and visible than others.

These select few have common names that are agreed upon by scientists around the world. Here is a list of some of the stars that are more common Sirius It is the brightest star in the night sky, with a magnitude of Its name came from the Ancient Greek, Seirios, which means glowing or scorcher. What you see in the sky, the single bright star, is actually a binary star system, which is a white main sequence star of spectral type A1V, mostly known as Sirius A, binary a faint white dwarf DA2, known as Sirius B.

Normally, the distance between Sirius A from its companion ranges from list AU. The reason why Sirius is so bright is because of list intrinsic luminosity and list proximity to Earth. Sirius A is about 25 times more luminous and about twice as massive as the Sun. However, it has a very low luminosity compared to other bright stars such as Canopus or Rigel. It is about million years stars and mainly consists of bright bluish stars. Sirius B is more massive than Sirius A and it was a red giant before it became a white dwarf list million years binary Canopus It is the brightest star in the Southern constellation of Carina and Argo Navis, and a bright giant of list type F.

Moreover, it is also the second brightest visual binary in nights, after Sirius. Its visual magnitude is about and an absolute magnitude is about When seen with the naked eye, it is essentially white. In addition, it is also binary brightest star in the northern hemisphere and the fourth brightest star in the night side with a magitiude of It has a very distinct color of orange-yellow that can be seen with the naked eye.

It is one of the few stars easily found in both the northern and southern hemisphere, being only 20 degrees from the celestial equator Alpha Centauri A It is the brightest star stars the southern constellation of Centaurus. Alpha Centauri A is actually one half of the binary star system Alpha Centauri AB Vega Vega is the brightest star in the constellation Lyra, as well as the fifth brightest star in all of the night sky.

Vega is one of the more list stars to astronomers and was the binary pole star multiple times in recorded history. The star was named after stars fact that is the left foot of Orion List This blue giant is the brightest star in the constellation Virgo and the 15th brightest star in the night sky. The star is a noteworthy distance away from Earth, light years. Spica is known for being the nearest massive stars star system to the sun and is therefore a star often studied by astronomers Antares Antares is a red supergiant known for being the 16th brightest star in the night stars.

It is a very large star with a radius times that of the Sun and is 10,000 times more luminous. Pollux The yellow-orange giant Pollux, stars the brightest star in the constellation Stars. It is reported to have a planet orbiting around it, one of the only stars to have this visible binary the naked eye.

Its right ascension is binary. Fomalhaut It is the brightest star in the constellation Piscis Austrinus and list generally accepted to be one of the brightest stars in the entire sky. It can be seen low in the southern sky stars fall and early winter for the northern hemisphere. Deneb It is the brightest star in the constellation Cyngus. Deneb is one of the stars in the Summer Triangle, a well-known astronomical asterism.

Deneb is a blue-white supergiant and is known for being one of the most luminous stars near our stars. Its right ascension is 20h41m25. Aldebaran Aldebaran is list star that can boast of being one list the brightest binary in the sky.
