WebExamples of visual binaries in the southern skies resolvable through small telescopes include α Crucis, β Crucis and γ Cen and Castor in Gemini. Some stars appear close together when viewed through a telescope but … WebA binary star is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a telescope as separate stars, in which case they are called visual binaries. Many visual binaries have long orbital periods of several centuries or millennia …

WebAmong these stars are many eclipsing binaries, Cepheid variables, and semiregular red variables, as well as a few long-period stars of the Mira type and the recurrent nova T Coronae Borealis. As many as 24 do not fade below magnitude 5.1 and so remain visible to the unaided eye all the time. WebExamples of binaries are Algol (an eclipsing binary), Sirius, and Cygnus X-1 (of which one member is probably a black hole ).

Astronomers have estimated that more than half of all stars in the Milky Way Galaxy are members of a double or a more complex multiple star system.
