A Retrograde Gravitational Capture Model for the Earth-Moon System

An Alternate Reality Scenario That May Yield Some Insights on the Habitability of Terrestrial Planets


A prograde capture scenario featuring a one moon-mass planetoid appears to explain a number of outstanding features of the Earth-Moon system and a retrograde capture scenario appears to explain a number of the outstanding features of planet Venus. A simple question is: COULD THESE SCENARIOS BE REVERSED? The answer is YES! BUT the probabilities of occurrence would be different for the two opposite scenarios.
