The discussion centers on the feasibility of two gas giants orbiting each other with a terrestrial planet positioned at their L4 or L5 points. For stability at these points, the mass ratio of the gas giants must exceed 25, with one giant being significantly more massive than the other. While a terrestrial planet could remain stable at these points for short durations, such as a year, long-term stability over billions of years is highly questionable. Even in stable orbits, the planet may face risks from perturbations, leading to potential ejection or becoming an impactor. The stability of a planet at the L4 or L5 points is less reliable compared to positions ahead or behind the gas giants, which may allow for longer-term survival. However, the likelihood of life evolving on such a planet remains doubtful, particularly beyond single-celled organisms.
