The swan's head, or top of the cross, is a star called Albireo. It is often referred to as “the beak star. Albireo. It also represents the Swan’s beak. Albireo Also known as Beta Cygni, Albeiro is a double star located around 430 light years from Earth, double stars are two stars that appear close to each other from Earth but may actually be separated by a large distance, the larger of the two stars is an orange giant with a radius around 70 times that of the sun. Albireo visual magnitude is 3.08. Albireo, Beta Cygni, is the star located at the base of the Northern Cross. The other double star we're going to look at, Albireo… The two stars which make up Mizar itself are almost equal in brightness (2.3 and 3.8 magnitude) and colour. To the naked eye, it's the fifth brightest star in Cygnus (combined mag. Key Facts & Summary Sadr is located at around 1,800 light-years / 560 parsecs away from the Sun. Seen at even slight magnification, Albireo unfolds from a bright single point into a beautiful double star of strikingly different colors. The contrast between the stars makes Albireo a pretty popular target among amateur astronomers. The nebula has the designation IC 1318. The components are located 35 arc seconds apart. Only 11th-magnitude Albireo C has shifted a bit in the past 68 years, but it appears the star is leaving Albireo A behind, so is likely unrelated. The Albireo / æ l ˈ b ɪr i oʊ / system is a double star designated Beta Cygni (β Cygni, abbreviated Beta Cyg, β Cyg).The International Astronomical Union uses the name "Albireo" specifically for the brightest star in the system. At 380 light years distant, the two bright stars of Albireo are comparatively far from each other and take about 75,000 years to complete a single orbit. Albireo. Sadr, designated as Gamma Cygni, is a star located in the northern constellation of Cygnus, forming the intersection of an asterism of five stars called the Northern Cross. Albireo is composed of a yellow star with an apparent magnitude of 3.18, which is in fact itself a close binary star, and a fainter blue companion star with an apparent magnitude of 5.82. The stars labeled D through L appear to be faint, unrelated field stars. Most star names are in fact Arabic and are frequently derived from translations of the Greek descriptions. No change in position angle or separation has occurred between observations. Albireo, also designated as β1 Cygni (beta1 Cygni), is a variable and multiple bright giant star in the constellation of Cygnus. Such is the case of the bright double star Albireo. The stars of Orion illustrate the various… The star’s name is derived from the Arabic word şadr, meaning “chest.” Sadr is surrounded by a diffuse nebula called the Sadr region or the Gamma Cygni region. Although designated 'beta', it is fainter than Gamma Cygni, Delta Cygni, and Epsilon Cygni and is the fifth-brightest point of light in the constellation of Cygnus. Albireo is a showpiece double star and one of the great small telescope objects. Beta Cygni or as it’s known more traditionally, Albireo is a binary star system within the constellation. A larger yellow star and smaller blue star are easily divided in a small telescope. Other articles where Albireo is discussed: astronomical map: Star names and designations: A conspicuous exception is Albireo in Cygnus, possibly a corruption of the words ab ireo in the first Latin edition of the Almagest in 1515. +2.9) and the lone star that marks the head of "the Swan" constellation.When viewed through small scopes - or even good 10x50 binoculars - it splits into two components. The brighter star of Albireo (or Beta Cygni) is magnitude 3.1, and the dimmer is magnitude 5.1. The star marking this point is known as Albireo, and is largely regarded as the most beautiful double star in the heavens.
