Building the ultimate Solar System

A while back I performed an experiment called build a better Solar System.  The game was to make better use of the Solar System’s habitable real estate.  In the game I was required to keep all of the Solar System’s planets (and large moons) and their orbital configurations.  Just by switching the orbits of different planets and moons I built a Solar System with seven potentially habitable worlds!  Here is what it looked like:

A re-imagined Solar System with seven potentially life-bearing planets!  The liquid water habitable zone is shaded in green.

This better system is a little different than the Solar System we have now.  Venus became one of Jupiter’s moons, Jupiter took Mars’ orbit, Mars took Venus’ orbit, and Earth’s moon was switched out for Titan (currently Saturn’s largest moon).  Good stuff.

Let’s take this game to the next level.  I want to build the ultimate Solar System.  I want to build a planetary system with the most possible habitable worlds. 

I hope you are not asking yourself why.  It’s all about imagination.  But, imagination constrained by science (and, to a lesser extent, by reality).  Imagine all the stories you could tell about a system with lots of habitable worlds!  Alliances, wars, vacations on other planets, even orbital trickery!

Let’s do this systematically.  I’ll discuss one piece of the puzzle at a time, then we’ll put them together.  I’m going to go nuts and do this all next week (19-23 May 2014).  Here is the layout (I’ll add links as these are posted).

1. What kind of star do we want? (Mon)

2. What kind of planets do we want? (Tues)

3. What types of orbits should planets have? (Weds)

4. Ninja moves: moons and co-orbitals (Thurs)

5. Putting it all together: some ultimate planetary systems.  (Fri)

 

Here we go!

    Fascinating!

    Dr. Raymond,

    I’m sure you’ve thought of it (you seem to have thought of everything else) but what about Klemperer rosettes? Talk about your ninja grand master moves.

    Three gas giants each have 5 earth-size moons and each gas giant has in its L4 and L5 positions co-orbital earth-size planets all in the same orbit. Times four in the habitable zone. 84 worlds. A binary system; 168.

    As for stability, perhaps the resonances would work out just well enough where as some worlds’ orbit begins to decay another planetary body in another orbit tugs just enough to pull or push the world back into place. Is this where the n-body problem peeks its ugly head out?

    But if I was REALLY crazy I would take a very large star and put six smaller stars (with your ultimate solar system) in each other’s L4 and L5 points, in the same orbit, in the habitable zone, around the very large star. A seven-star system. Would it be too hot with the energy from both a supergiant star and a main sequence star?

    Please let me know.

    And thank you, it is nice to know I am not the only one thinking about this stuff.

    Very Respectfully,

    Evan Stark

      Evan — great question. Your idea is awesome! I had heard of Klemperer rosettes but never studied them. In my own work I have never ended up with more than 3 planets sharing the same orbit, and even that was quite a surprise (and if I remember right, it was not stable in the long term).

      Unfortunately, wikipedia tells me that the Klemperer rosette is an unstable equilibrium, meaning that any small perturbation from the exact alignment will make the system go unstable: http://en.wikipedia.org/wiki/Klemperer_rosette . Since all systems are invariably perturbed a little (for example, by the planets/moons orbiting the primary bodies in the rosette), this is bad for business. I do think this is a cool idea that warrants more study though. Maybe there is a subset of rosettes that remain stable.

      Anyhow, thanks for the very interesting comment
