Albireo - Albireo Albireo is a double star found in the constellation Cygnus ("the swan"). It is considered the "beak star", located at the head of the swan; as the second-brightest star in Cygnus, it is also known as Beta Cygni (β Cyg). When viewed with a telescope, it readily resolves into a double star, one yellow (apparent magnitude 3.1), the other blue (apparent magnitude 5.1), providing one of the best contrasting double stars in the sky. The pair is located 385 light years away, and initially it was believed that the stars were merely an optical double, not orbiting around a common point as a true double star system would be. However, in spite of the large distance between them (400 billion miles, or 50 times the.

Deneb, α Cygni, is an extremely brilliant star, very prominent despite its distance (1 800 light years). The blue supergiant forms the swan's tail, the upper end of the Northern Cross, and one of the vertices of the so-called "Summer Triangle". Albireo, β Cygni, is at the swan's beak. It is one of the most beautiful double stars of the sky, a golden star easily distinguishable in a small telescope from its blue companion. Another interesting star is 61 Cygni. This star has one of the highest proper motions of any star in the sky (except the Sun) and was accordingly one of the first to have its distance measured. It.
