A new article in the Sci. Am. magazine is not available on line, but its summary is simple. Our solar system is very unusual ("relatively rare") to what is seen elsewhere. It's evolution caused it to be hollowed out near the sun to allow rocky metal containing planets to orbit in close while the gas giants are outside. A possible discovery of planet nine fits the current theories and findings which suggest that larger bodies are pushed outward. The final configuration arrived about 3.8 billion years ago, which is the same time life may have started on Earth. Since life is here, this is either a simple requirement of what had to happen or good planning for a purposeful event. Take your choice. Much of this is based on computer simulations. I will present more material if I can find it on line.-Note the entry of Tuesday, February 02, 2016, 05:40 where it is shown only 6% of solar systems have some resemblance to ours.
