Why is the long-term existence of planets more difficult in multiple star systems?

Answer

Chaotic orbital dynamics and potential gravitational ejection

In systems with multiple stars, the gravitational environment is complex. Unlike single-star systems, which often offer more stable zones for orbits, multiple star systems create chaotic dynamics. These unstable gravity fields frequently result in orbiting bodies being ejected from the system entirely, making the permanent residence of a planet unlikely.
