    An eclipsing binary star is a binary star system in which the orbital plane of the two stars lies so nearly in the line of sight of the observer that the components undergo mutual eclipses. [20] In the case where the binary is also a spectroscopic binary and the parallax of the system is known, the binary is quite valuable for stellar analysis.

    Definitions vary, but typically require the center of mass to be located outside of either object. (See animated examples.) 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.

    The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...

    Artist's rendering of the massive contact binary star VFTS 352, located in the Large Magellanic Cloud. In astronomy, a contact binary is a binary star system whose component stars are so close that they touch each other or have merged to share their gaseous envelopes. A binary system whose stars share an envelope may also be called an ...

    en.wikipedia.org/wiki/Antares

    If placed at the center of the Solar System, it would extend out to somewhere in the asteroid belt. Its mass is calculated to be around 13 or 15 to 16 times that of the Sun . [ 10 ] Antares appears as a single star when viewed with the naked eye, but it is actually a binary star system, with its two components called α Scorpii A and α Scorpii B.

    Unlike the lonely sun, about half the stars in our Milky Way galaxy are in a long-term committed relationship with another star, orbiting each another in a celestial marriage called a binary system.

    55 Cancri is a binary star system located 41 [1] light-years away from the Sun in the zodiac constellation of Cancer.It has the Bayer designation Rho 1 Cancri (ρ 1 Cancri); 55 Cancri is the Flamsteed designation (abbreviated 55 Cnc).

  9. Kepler-47 - Wikipedia

    en.wikipedia.org/wiki/Kepler-47

    Kepler-47 is a binary star system located about 1,055 parsecs (3,440 light-years) away from Earth. [14] The binary system is composed of a G-type main sequence star (Kepler-47A) and a red dwarf star (Kepler-47B). The stars orbit each other around their barycenter, or center of mass between them, completing one full orbit every 7.45 days. [4]
