Note that the rays from the impacts match no known class of asteroid, period.
They lay on the surface, and are not an exposed sub-surface, period.
Now gravity is going to favor a perfectly spherical distribution of material, period.
But if the accretion pattern favors one area....
the volatiles will outgas after a short while...
metals migrate downward...
the ooze flows? or do pressures cause a sub-surface collapse?
