Did Venus Eat Its Moon? Scientists Weigh Planetary Collisions
Scientists theorize that Venus may have swallowed a rocky satellite, shifting decades of belief that Earth's twin never possessed a moon. While small planets like Mercury and Venus possess tiny Hill sphere radii that limit gravitational pull, researchers debate whether ancient moons were pulled into the Sun, knocked away by impacts, or consumed directly through planetary collisions driven by powerful gravity. Meanwhile, Earth maintains its single natural satellite at an average distance of 384,399 kilometers, bound by gravitational attraction that creates tidal locking.
Why it matters
Understanding why Venus lacks a moon helps astronomers evaluate how rocky planets evolve and retain satellites across the cosmos. Small planets struggle to hold onto satellites due to weak gravitational spheres, leaving them vulnerable to solar interference or catastrophic impacts. Researchers continue to investigate formation histories by comparing Earth's lunar system with the barren conditions of other inner planets.
