This could be a natural phenomenon. See https://en.wikipedia.org/wiki/Orbital_resonance
In spite of the title no one is wondering if aliens moved planets around to park them in special orbits. It's infinitely more likely the resonances developed naturally.
Also, none of the planets are in the habitable zone, so it's unlikely there's life on them.
Which is a shame, because if the star was much dimmer and they were in the habitable zone, the views would make a stunning tourist attraction.
Why would somebody want to live on the arms of a clock??
Taken another way: Venus’ atmosphere would get more “tame” further out. That might make it more conducive to life. But would its atmosphere still form at those distances? (Clearly it’s not impossible.)
