Venus Lost Moon To Celestial Cannibalism Theory

BusinessLine · science

A new theory suggests Venus lost its moon due to its extremely slow rotation. Scientists propose that any moon orbiting Venus would have gradually spiraled inward and crashed into the planet. This celestial cannibalism likely occurred within the first billion years of Venus's history. Previous explanations included Venus never having a moon or one being obliterated by an impact. The study highlights planetary rotation speed as a key factor in moon retention.
