The line of sight from earth to the star system must be very close to the orbital plane of the stars to see eclipses of stars in binary star systems.
Each star in a double star system, also known as a binary star system, gravitationally pulls in the second star, which circles around the pair's centre of mass. Each star will be seen to eclipse the other once every orbital period if their orbital plane is edge-on to Earth. Eclipsing binary is the name for such a system.
It is also referred to as an eclipsing variable star because in an eclipsing binary system, the total amount of light fluctuates on a regular basis. When one of the two stars in an eclipsing binary is eclipsed, the light curve of the system experiences a deep minimum, and when the other star is eclipsed, the light curve experiences a shallower minimum.
