1, system: The main star is the brightest and most important star in the system. The main star plays a leading role in the structure and dynamics of the whole system. The satellite is relatively small, and it is the companion or satellite of the main star, which has little influence on the system.
2. Quality: The interaction between two satellites will be relatively weak, resulting in relatively small impact. The mass and luminosity of the main star will have a great influence on the interaction and influence between the two stars.
