Is there any intrinsic biase in the manner with which KBO searches are made which predisposes them to finding objects in particular direction in the sky, or follow orbits or particular Eccentricities?
Btw, regarding the notion that KBO thus far discovered were similar due to some common origin rather than common subsequent influence, what about they were all remnants of a collision event that completely disrupted the parent body of a system of moons? The remains of the parent body and any prior moons subsequently evolved to its current range of orientations and eccentricities, while the parent body is no longer there?
Or alternatively the parent body, although still there and larger, is near apihelion, so harder to see, while the subset of the family thus far discovered are mostly at or near perihelion, thus easier to see?
Just out of curiosity, what would be the expected rate of the precession of major axis of an elliptical orbit at this distance? It is reasonable to assume a family of objects with a common origin 4.5 billion years ago would retain a degree of similarity in the orientation of the axis of their orbits after 4.5 billion years comparable to what we see now?
