A binary star or binary star system 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 as separate stars using a telescope, in which case they are called visual binaries. Many visual binaries have long ...
Planets in binary star systems may be candidates for supporting extraterrestrial life. [1] Habitability of binary star systems is determined by many factors from a variety of sources. [2] Typical estimates often suggest that 50% or more of all star systems are binary systems. This may be partly due to sample bias, as massive and bright stars ...
A binary system is a system of two astronomical bodies of the same kind that are comparable in size. Definitions vary, but typically require the center of mass to be located outside of either object. (See animated examples.)
TOI-1338 is a binary star system located in the constellation Pictor, about 1,320 light-years from Earth.It is orbited by two known circumbinary planets, TOI-1338 b, discovered by the Transiting Exoplanet Survey Satellite (TESS) [2] and BEBOP-1c, discovered by the Binaries Escorted By Orbiting Planets project.
In astrobiology and planetary astrophysics, the galactic habitable zone is the region of a galaxy in which life is most likely to develop. The concept of a galactic habitable zone analyzes various factors, such as metallicity (the presence of elements heavier than hydrogen and helium) and the rate and density of major catastrophes such as supernovae, and uses these to calculate which regions ...

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.
