The fifth star in Cygnus above magnitude 3 is Aljanah, [23] designated ε Cygni. It is an orange-hued giant star of magnitude 2.5, 72 light-years from Earth. [25] [26] There are several other dimmer double and binary stars in Cygnus. μ Cygni is a binary star with an optical tertiary component. The binary system has a period of 790 years and is ...
Deneb (/ ˈ d ɛ n ɛ b /) is a first-magnitude blue supergiant star in the constellation of Cygnus. Deneb is one of the vertices of the asterism known as the Summer Triangle and the "head" of the Northern Cross. It is the brightest star in Cygnus and the 19th brightest star in the night sky, with an average apparent magnitude of +1.25.
61 Cygni / ˈ s ɪ ɡ n i / is a binary star system in the constellation Cygnus, consisting of a pair of K-type dwarf stars that orbit each other in a period of about 659 years. Of apparent magnitude 5.20 and 6.05, respectively, they can be seen with binoculars in city skies or with the naked eye in rural areas without light pollution.
Eta Cygni (η Cygni) is a star in the northern constellation of Cygnus. It is visible to the naked eye with an apparent visual magnitude of 3.889. [2] The star lies along the main body of the constellation, about midway between Gamma Cygni and Albireo. [9] Based upon an annual parallax shift of 23.55 mas, [1] it is located 138.5 light years ...
SS Cygni is a variable star in the northern constellation Cygnus (the Swan). It was discovered in 1896 by Louisa D. Wells, a computer working under Edward Pickering at Harvard College Observatory. [7] [8] It is the prototype of the subclass of dwarf novae that show only normal eruptions. It typically rises from 12th magnitude to 8th magnitude ...
ξ Cygni (Latinised as Xi Cygni) is a spectroscopic binary star in the constellation Cygnus, made up of a K-type supergiant star (primary) and an A-type star (secondary). Its apparent magnitude is 3.73, making it readily visible to the naked eye, and it is located around 350 parsecs (1,100 ly) away.
Tau Cygni, Latinised from τ Cygni, is a binary star system in the constellation Cygnus, approximately 69 light years away from Earth. [4] This visual binary system has a period of 49.6 years. [2] The main star, 4th magnitude GJ 822.1 A, is a yellowish white subgiant star of the spectral type F2IV.
