Light weight icy Pluto and Eris are smaller KBO objects that have moonlets. Why not our more massive Moon?
For our Moon, is what we see is result of a historical event, a collision between proto earth and a planetesimal?
Our Moon that formed from such collision, was very close to earth initially (30-60 degree arc angle compared to current meridian value of 1/2 degree?). How close to earth, compared to current approximately 230,000 miles; and where was the Lagrange point, compared to it’s current closeness (~60 km?) to our Moon?
Might one visualize such Lagrange point as a ‘curvature ridge’, with a slow roll, inversely to gravitational potential? Or more rapid inverse cube tidal interactions? Would there be enough space and stability for formation and persistence of moonlets?
Thus would the lack of such moonlets now be consistent with the historical closeness of our Moon, and hence another argument consistent with a prior collision of planetesimals with proto earth?
Why don’t the more massive jovian and saturnian moons have moonlets? Perhaps the result of a different history and environment than for Kuiper Belt Objects?
