i hate when your ‘roids get out of sync with your planet!
Fortunately the orbital periods are so long (about 11.8 years) that if it does not get caught by Jupiter’s gravity and “slingshotted” towards Earth this time around, I’ll (probably) be dead by the time it does. And my heirs will have found a way to deflect it.
retrograde motion is not natural and could be a signal or sign post saying,”Look at me; there’s something here” ... aliens again!
But point of fact, there are a lot of inexplicable oddities surrounding the moons of Saturn and Jupiter.
Like it's the one that's going the wrong way. How do they know everyone else isn't going the wrong way?
