✨ Could the TRAPPIST-1 planets host moons despite their compact orbits? 🌌 — A new study suggests that natural satellites are dynamically possible around the seven Earth-sized worlds of the TRAPPIST-1 system, but only if they remain small and orbit very close to their host planets. Despite intense gravitational interactions within this tightly packed system, there is a stable region near each planet where moons could persist, although current detection methods are not yet sensitive enough to confirm their existence.
