How Reliable is Bode's Law? Is Bode's Law just a series of remarkable coincidences,or would it hold good for other solar systems where the star is similar to our sun?
A recent article examines if exoplanetary systems follow the Titus-Bode rule. They find that among the systems with three or more confirmed planets that they studied, the planetary distances follow a logarithmic law roughly 53% of the time. So it is possible that the Titus-Bode rule is more than a simple coincidence.
There is no solid explanation for this, but from Wikipedia:

it is possible that, given a combination of orbital resonance and shortage of degrees of freedom, any stable planetary system has a high probability of satisfying a Titius–Bode-type relationship.
