And what can this mean except that, like those planetary orbits which seem to traverse our solar system without remaining within it, the curve of consciousness, pursuing its course of growing complexity, will break through the material framework of Time and Space to escape somewhere towards an ultra-center of unification and wholeness, where there will finally be assembled, and in detail, everything that is irreplaceable and incommunicable in the world.

Some of them are orbiting extremely close to their parent star like the 51 Peg planetary system, while others are found to be at distances comparable to where Mars and Jupiter lie in our solar system.

The other factor that arises from this is that CMEs, of all the various dangerous stellar eminations, appear to be most responsible for planetary atmospheric erosion so anything that mitigates their effect has got to be good in terms of planetary habitability and most of all in M dwarf systems where the «habitable zone» is close to the star and well within the region of synchronous rotation.
