What is Binary Star?

In astronomy, binary star is a star system consisting of two gravitationally bound bodies. The two stars follow Kepler’s laws of motion and in elliptical or circular orbits circle their shared centre of mass. Any relativistic devices, such as binary pulsars, exhibit behavior that can be explained only by using the general relativity theory of Einstein.
