A binary star system that is detected from the drop in luminosity as one star passes in front of the other is called eclipsing. It has two stars.
What is a binary system?
A binary system is a system composed of two stars that exert gravitational forces on a group of celestial bodies.
In a binary system, planets and celestial bodies can exhibit well-defined or irregular (very unstable) orbits.
The eclipsing binaries are stars where binary planets orbit in a plane containing the same line of vision, thereby eclipsing each other.
