    The 'we' in this thread title refers to our solar system.

    An article in New Scientist : 14 May 2011 page 47 (paper copy)

    It reviews the results of extra-solar planet finding, with over 200 planets so far discovered in a little under 200 star systems. The surprise finding is that nothing like our solar system has yet been discovered.

    Our solar system is atypical. We have a system with small rocky planets close to the sun, and large gas giants further out. All are in almost circular orbits, moving in a well behaved, stately way, around the sun. And of course, we have Earth in the liquid water belt, also in a beautiful, stable, almost circular orbit.

    Other stellar systems have all kinds of different systems. Giant planets orbiting very close to their parent star are common. Wildly eccentic and elliptical orbits. Planets massively bigger than Jupiter. Every indication of violent interactions between bodies within those systems.

At first glance it seems that all this is true. But consider the system Gliese 581. We write the order of the values of orbital radii: 0.030, 0.041, 0.073, 0.146, 0.220, 0.758. Multiply this numbers by 23.65. Obtain a series of numbers: 0,71, 0,97; 1.73, 3.45, 5.20, 17.9. What is it?

Comparable to the orbital radius of planets in the solar system:
0.71 ; 0.97 ; 1.73 ; 3.45 ; 5.20 ; --- ; 17.9
0.72 ; 1.00 ; 1.52 ; ---- ; 5.20 ; 9.54 ; 19.1
As you can see, there is an obvious similarity, which confirms that planetary systems are created for one scenario.
Although over five hundred planets discovered so far, but there are the only 7 systems are multyplanetary enough (more 3 planet) for reliable analysis. There are : Gliese 581, Gliese 876, 55Cancri, Upsilon Andromedae A system, My Arae, HD10180, Kepler-11. And all of them have made in accordance with an universal principle (but not Bode-Titius's "Law"). More over, systems of moons of Saturn, Jupiter, Uranus have made in this way.
Note the following important fact. When comparing the solar system with a system Gliese 581 major satelites of the systems have coincided to each other. This is our general principle.
Let's draw up a comparative table of the six systems (left to right): Gliese 581, Solar, Saturn, Uranus, Jupiter, Gliese 876. Orbital radius of the largest satelites take equal to 1. This celestial bodies are: Gliese 581 d, Jupiter, Titan, Titania, Ganymede, Gliese 876 e. Consider the part of systems lying below the orbits of primary satelite. Obtain the table:
