trinary star systems

A trinary star system consists of three stars that are gravitationally bound and orbit each other. These systems can have different configurations, such as a close pair with a distant third star or three stars evenly spaced. Their complex gravitational interactions influence their orbits, which can be stable or unstable over long periods. Trinary systems are more common than you might think and provide unique insights into stellar dynamics and formation. Observing these systems helps astronomers understand how multiple stars form and evolve together in our galaxy.
