Hello all, hope you had happy holidays and new year. I had some questions regarding atmospheres, breathable mostly and what conditions are required on a planet to sustain them. Could a low gravity planet with the temperature of earth maintain a breathable atmosphere? Could it be given one that could be sustained artificially? Also, could a planet have an extremely low escape velocity, e.g. something small (my math is not great so I use small numbers for my example) like 3 meters per second (maintained through as a constant force, like say a 3 m/s elevator) being able to leave the planet. could it still have temperatures akin to Earth? What would the gravity be like? Could it maintain any breathable atmosphere? Thanks all for answers, I am interested in both the facts and theories behind these ideas.
