Somewhat inspired by this question : Could a civilization as advanced as humans exist on a planet/dwarf planet like Pluto?
Assume two dwarf planets in tide lock orbit around one-another. Assume same mass for the two bodies. Ignore how it developed (atmosphere could be placed their artificially)..and assume tiny gravity.
Is it possible for an atmosphere to remain stable in the space between these two bodies?
I assume there is a place between these two bodies as they orbit each other where gravity is basically cancelled out by the two bodies and have an area in the center of microgravity. Could an atmosphere of sorts exist between these two bodies, suspended between the two? If yes, would the atmosphere extend to the planets surfaces? What type of orbital speed would there need to be to keep this semi stable (by stable I mean exist for a couple hundred years, artifical processes could be regenerating it...just curious if it'd simply dissipate or if the system could be stable.
As an alternative, could this setup be realistic with larger planetary bodies? Could multiple bodies (4+, or even rings) orbitting in this setup have a stable atmosphere in between them?
This isn't looking for local life on either planet...go with the vision of an artificial habitat put into the center of this planetoid setup (including the atmosphere being artificially generated when the setup was created). Would the atmosphere be stable, or would it dissipate as fast as it's created? Would it be feasible to exit the space station and wander around in this atmosphere?
