I The Sun's habitable zone and orbital resonaces/stability

  1. May 11, 2017 #1
    Let's say there's five Mars/Earth massed planets orbiting a star like the sun between 0.6 AU and 2 AU, what orbital resonance configuration can they be in to ensure maximum stability? Would adding gas giants to the system enhance stability?

    For Earth-like masses and a Sun-like central star, you can pack planets very close while maintaining billions of years of orbital stability. This website has a calculator. Earth excludes further planets in the range from 0.95 to 1.05 AU, a very narrow range. Smaller masses exclude even smaller regions.
