I don't really think of Nature being scientifically "ruled" by the orbiting planets. To me its more a reference system of the interconnectedness of all creation. If you think of the universe as a holographic entity (all parts, even the most minute, containing the entirety), then the association of ruling planets takes on a more psycho-spiritual context. We humans tend to observe, associate and interpret the world around us in a poetic and metaphysical fashion. This isn't necessarily *incompatible* with scientific observation. Just a different lens to view the world through.

What is determined to be a planet is a fashion. Pluto got demoted to a planet-like object, which actually is a duo-body closely orbiting itself.
The recent science from the NASA Cassini probe orbiting the moons of Saturn shows at least two Saturnian moons Have organic chemicals, water/ice, and tidal energy from Saturn and it's ten moons. Think of the heat produced when you bend a paper clip,these large bodies orbiting each other produces energy. Think of the regular tides each day on Earth.
The Saturn moon Enceladus even has the signs of having a liquid ocean underneath it's Southern pole. Enceladus is active, producing inner heat, with the same conditions as deep sea mineral vents miles deep in our Earthly oceans.
All the same conditions for life also are possible on Europa, a moon of Jupiter. And of course, Mars.
Bacteria have been found miles deep in the Earth's mantle, far removed from our Solar life energy.
Amazing how we are learning more about how our little podunk solar system way off in the boonies may be more hospitable for life than what we used to be taught.
And that extra-terrestrial life which may be found soon close to our home may very well be a type of fungus.
