Rogue Planets – Austin Bunton Designs

These are the worlds that drift between the traditional solar-systems we are more familiar with.

In the ancient past (during the first Golden Age; when the whole of Creation was pleasant, warm, and connected by an interstellar ocean), all these worlds, rogues though they were (or would become; once the worlds and systems spread out, no longer holding/balancing/sustaining them), were temperate and tropical paradises full of abundance and peace.

Planemo Group (“Rogues”), Class R:

orbit: not gravitationally bound to any star, depths of interstellar space.
Some formed naturally without a star,
others gravitationally ejected from their home systems,
some routinely traded between ejecting/collapsing/destabilizing systems. When teleportation and worm-holes are not options to relocate planets and stars, often sentient civilizations opt to make their planet habitable during long-term, slower transit/migration to available orbit brackets in compatible star systems.

Sub-types:

Hauhetean

primary atmospheres: hydrogen and helium,
mass: not great enough to maintain an internal geology.

Nyxian

Mass: not enough to retain primary hydrogen-helium atmospheres.
Atmos’: slips away
Some have a secondary atmosphere formed by volcanic out-gassing, if they are massive enough to maintain such activity.

Stevensonian

atmosphere dense traps heat from internal geological activity, which creates pockets of habitability on the surface.
Some are heated to an extent that entire surface may be habitable. –Summer is based on volcanic-seasons/activity (when there is no tilt, wobble, or elliptical orbit)and the science of stimulating and regulating volcanoes is at artisan levels.
