  2. Binary star - Wikipedia

    en.wikipedia.org/wiki/Binary_star

    Antares (Alpha Scorpii) is a red supergiant star in a binary system with a hotter blue main-sequence star Antares B. Antares B can therefore be termed a hot companion of the cool supergiant. [41] Symbiotic stars, such as R Aquarii, are binary star systems composed of a late-type giant star and a hotter companion object. Since the nature of the ...

    en.wikipedia.org/wiki/Binary_system

    The most common kinds of binary system are binary stars and binary asteroids, but brown dwarfs, planets, neutron stars, black holes and galaxies can also form binaries. A multiple system is similar but consists of three or more objects, for example trinary stars and trinary asteroids .

    The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A , which is also the brightest star in Earth's night sky ; its white dwarf companion Sirius B is the hottest object among them.

  7. Circumbinary planet - Wikipedia

    en.wikipedia.org/wiki/Circumbinary_planet

    In contrast, circumstellar planets in a binary system have stable orbits around one of the two stars, [1] closer in than the orbital distance of the other star (see Habitability of binary star systems). Studies in 2013 showed that there is a strong hint that a circumbinary planet and its stars originate from a single disk. [2]

  8. Sirius - Wikipedia

    en.wikipedia.org/wiki/Sirius

    Sirius is a binary star system consisting of two white stars orbiting each other with a separation of about 20 AU [e] (roughly the distance between the Sun and Uranus) and a period of 50.1 years. The brighter component, termed Sirius A, is a main-sequence star of spectral type early A , with an estimated surface temperature of 9,940 K . [ 14 ]
