"Until now, said the researchers, it was not possible to explain the unique features of Arrokoth. It is a counter intuitive result, but the likelihood of collision in such configurations actually increases as the initial binary is more widely separated (but still bound) and the initial tilt angle is closer to 90 degrees."
