A trinary star system is a rare occurrence in the universe, where three stars orbit around a common center of mass. Other terms that can be used to describe this phenomenon include "ternary star system," "triple star system," or "triple star." In some cases, these stars can be categorized as "hierarchical triple stars," where two of the stars orbit each other closely, while the third star orbits them from a greater distance. Trinary star systems can provide unique insights into the dynamics of orbital mechanics and the formation of planetary systems. These systems are fascinating objects that continue to captivate astronomers and scientists alike.
